WHAT IS VIRTUALIZATION TECHNOLOGY?
In computing, virtualization or virtualisation is the act of creating a virtual version of something, including virtual computer hardware platforms, storage devices, and computer network resource
Virtualization is technology that lets you create useful IT services using resources that are traditionally bound to hardware. It allows you to use a physical machine’s full capacity by distributing its capabilities among many users or environments.
What is the use of virtualization technology?
Virtualization relies on software to simulate hardware functionality and create a virtual computer system. This enables IT organizations to run more than one virtual system – and multiple operating systems and applications – on a single server. The resulting benefits include economies of scale and greater efficiency.
How to Maximize Efficiency With Virtualization Software
By on April 13, 2020
Typically, enterprise data centers consist of lots of servers, most of which sit idle as the workload is directed to only a few servers on the network. This results in wastage of expensive resources, hardware, power, maintenance, and cooling requirements. Virtualization helps increase resource usage by partitioning a physical server into multiple virtual servers. These virtual servers look and act like an individual physical server running its own operating system and applications. This concept of virtualization is used in almost every IT infrastructure as it helps multiply the capacity of physical machines. It helps to fully utilize existing resources, thereby minimizing the overall cost of business. Organizations use virtualization software (also known as a hypervisor) to create virtual machines, networks, desktops, and servers.
Virtualization software makes IT simpler to manage and cost effective to own and operate. It brings various positive transformations such as reduced hardware costs, better disaster recovery solutions, increased IT agility, enhanced performance, and quick availability of resources. To integrate virtualization, it’s important to understand its different types. Businesses can choose the type of virtualization they need based on their requirements.
TYPES OF VIRTUALIZATION
Desktop virtualization is when the host server can run virtual machines using a hypervisor (a software program). A hypervisor can directly be installed on the host machine or over the operating system (like Windows, Mac, and Linux). Virtualized desktops don’t use the host system’s hard drive; instead, they run on a remote central server. This type of virtualization is useful for development and testing teams who need to develop or test applications on different operating systems.
The process of installing an application on a central server (single computer system) that can virtually be operated on multiple systems is known as application virtualization. For end users, the virtualized application works exactly like a native application installed on a physical machine. With application virtualization, it’s easier for organizations to update, maintain, and fix applications centrally. Admins can control and modify access permissions to the application without logging in to the user’s desktop. Another benefit of application virtualization is portability. It allows users to access virtualized applications even on non-Windows devices, such as iOS or Android. This helps save user’s time invested in application installations and load operations.
Server virtualization is a process of partitioning the resources of a single server into multiple virtual servers. These virtual servers can run as separate machines. Server virtualization allows businesses to run multiple independent OSs (guests or virtual) all with different configurations using a single (host) server. The process also saves the hardware cost involved in keeping a host of physical servers, so businesses can make their server infrastructure more streamlined.
Network virtualization helps manage and monitor the entire computer network as a single administrative entity. Admins can keep a track of various elements of network infrastructure such as routers and switches from a single software-based administrator’s console. Network virtualization helps network optimization for data transfer rates, flexibility, reliability, security, and scalability. It improves the overall network’s productivity and efficiency. It becomes easier for administrators to allocate and distribute resources conveniently and ensure high and stable network performance.
Storage virtualization is the process of pooling physical storage of multiple network storage devices so it looks like a single storage device. Storage virtualization facilitates archiving, easy backup, and recovery tasks. It helps administrators allocate, move, change and set up resources efficiently across the organizational infrastructure.
WHY DO ORGANIZATIONS USE VIRTUALIZATION SOFTWARE?
Virtualization software, also known as hypervisors, helps organizations simulate hardware functionality and create multiple virtual computer systems. This helps IT teams use multiple applications and operating systems on a single server. Organizations use virtualization software to efficiently manage and allocate resources to virtual machines. When using virtual machines, if one of them crashes, it has no effect on the physical hardware or other virtual machines.
HOW TO CHOOSE THE BEST VM SOFTWARE
Before choosing a VM software, it’s important to consider three main factors: CPU, memory, and network I/O capacity. They’re all critical for workload consolidation. When evaluating hosted hypervisors, open-source solutions, and bare-metal implementations, organizations also need to consider how these options affect their security, governance, and compliance policies. A few big players in the market offer several functions an organization might require, but SolarWinds Virtualization Manager is among the top choice of administrators due to the ease of implementation, advanced features, and cost-effective pricing plans.
Benefits of Virtualization
- Reduced upfront hardware and continuing operating costs.
- Minimized or eliminated downtime.
- Increased IT productivity and responsiveness.
- Greater business continuity and disaster recovery response.
- Simplified data center management.
- Faster provisioning of applications and resources.
The best virtual machine for Windows 10
As we have already covered, the hypervisor plays a crucial role in virtualization technology’s capabilities and functionality. There are many different hypervisor solutions on the market today, some paid products and others that are free. In this guide comparing the various features of different hypervisors available, we will consider the best virtual machine for Windows 10 and other VM workloads you may have. Let’s look at the following available hypervisors:
- VMware Workstation Pro and Workstation Player
- VMware ESXi
- Microsoft Hyper-V
- VMware Fusion Pro and Fusion Player
How does each of the available hypervisors compare and contrast in terms of price, features, compatibility, and other aspects?
Virtualbox is an extremely well-known x86 and AMD64/Intel64 virtualization solution widely used from the enterprise data center to the home user and enthusiast alike. It is a Type 2 hypervisor that runs across a wide range of platforms, including:
It also supports many guest operating systems that range from legacy OS’es to the latest versions of Windows, Linux, Solaris, OpenSolaris, OS/2, and OpenBSD. It makes it an excellent platform for playing around with, testing, learning, and running workloads for various use cases. For those keenly interested in Windows virtualization, VirtualBox provides one of the healthiest arrays of different Windows OS’es available for virtualizing, including legacy Windows operating systems back to Windows 3.1.
Virtualizing Windows 10 with Oracle VirtualBox
In particular, VirtualBox runs Windows 10 very well and provides many different settings and features that allow a seamless and pleasant experience with the Windows 10 OS across its various flavors. One of VirtualBox’s “features” that stands out is it is an open-source program that is free. You pay no license fees or any other fees to use and run the software. Some may be a bit concerned about VirtualBox’s open-source nature regarding support and any issues that may arise. However, VirtualBox has a healthy following and is a community-supported product with support from VirtualBox gurus on the forums.
VirtualBox is easy to run and requires very little to no previous experience with other hypervisors to get up and running with Windows 10 in a VM. The software interface is intuitive and easy and features a very “point and click” oriented approach to running your VMs. However, while you can certainly accept the defaults with the program, it features many extra “nerd knobs” you can tweak to your liking with your VMs.
One of the features that may especially appeal to Windows 10 virtualization for some users is a new feature called seamless mode. With the seamless mode functionality of VirtualBox, you can display windows found in a virtual machine side by side next to the windows shown in your host. After the seamless mode functionality is enabled, VirtualBox suppresses the display of your guest’s desktop background. It makes the windows appear seamlessly next to host windows, which provides the feel of the window from the guest operating system residing natively on the host.
VirtualBox provides a robust set of network management features that allow customizing networking and connectivity as needed while using VirtualBox. VirtualBox certainly does not disappoint with the networking features made possible with the VirtualBox Host Network Manager. Using the Host Network Manager, you can create new virtual networks configured manually or automatically. You can also configure your host networks with DHCP capabilities for guest IP configuration running on a particular host network segment.
VirtualBox Host Network Manager
Below, we enable the DHCP server on a new Host-only network segment configured using the Host Network Manager in VirtualBox. You can configure the DHCP server IP address ranges assigned to guests.
Configuring the Host Network Manager DHCP server
The flexibility offered by VirtualBox allows configuring your Windows 10 VMs and others for various types of connectivity use cases, test scenarios, lab environments, etc. It is nice to see that VirtualBox provides a robust feature set in the area of networking. Networking support is arguably one of the most important functional features and capabilities to look for with a hypervisor.
What about nested virtualization? Nested virtualization allows you to run a hypervisor inside another hypervisor. Why is this important? Suppose you want to use Hyper-V inside a Windows 10 test VM that you have running inside a hypervisor such as VirtualBox. Having the ability to use nested virtualization means you can test and use Hyper-V installed on your Windows 10 virtual machine running inside VirtualBox. VirtualBox supports this by enabling nested virtualization at the VM level.
Nested virtualization allows exposing the physical processor’s virtualization settings on your virtualization host to an underlying virtual machine. With VirtualBox, you can enable nested virtualization using either the GUI or the command-line.
Enabling nested virtualization on a Windows 10 VM running in VirtualBox
From the command-line in VirtualBox, you can enable nested virtualization using the following commands:
- Vboxmanage.exe list vms
- Vboxmanage.exe modifyvm “<your VM>” –nested-hw-virt on
Using the VirtualBox command-line to enable nested virtualization
Another point to mention with VirtualBox is Oracle has provided several pre-built VirtualBox VMs readily available for download. For the most part, the VMs cater to developers who want quick access to developer VMs running Oracle. These are Linux boxes that come preinstalled with developer tools to interact with Oracle and other solutions.
VMware Workstation Pro and Workstation Player
VMware Workstation has long been a standard in desktop virtualization in the enterprise and for power users. It is a Type 2 hypervisor that provides the “Cadillac” of features that offer users robust capabilities to run Windows 10 virtual machines and many other types of workloads, including containers. What features does VMware Workstation provide?
VMware Workstation Pro provides an excellent desktop virtualization platform
- Ability to run VMs, containers, and Kubernetes clusters on a single workstation
- Work with a wide range of operating systems and technologies
- It offers a robust set of nested virtualization features
- Interact with and even manage VMware vSphere environments
- Provide secure, isolated environments for development, testing, and other use cases
VMs, Containers, and Kubernetes
With VMware Workstation, you can run multiple virtual machines, OCI containers, and Kubernetes clusters on the same Windows or Linux host running VMware Workstation. You can create fully segmented and isolated networks with network condition simulation. The platform provides a “Swiss Army knife” solution that is an excellent choice for developers, solutions architects, application testing, and demonstrating product functionality.
Work with a wide range of operating systems and technologies
VMware Workstation provides the ability to work with a wide range of operating systems, including the Windows 10 operating system’s latest versions. You can also work with OCI containers and Kubernetes clusters using kind and Minikube.
Robust set of nested virtualization features
VMware Workstation is known for its abilities in the realm of nested virtualization. You can easily configure and provision an entire lab containing Windows 10 workstations, Hyper-V, and nested virtual machines running on Windows 10 with the Hyper-V role installed.
Interact with and manage VMware vSphere environments
One of the great features you get with VMware Workstation is interacting with and managing VMware vSphere environments. If you have an existing enterprise VMware vSphere environment, you can use your VMware Workstation GUI dashboard to add and manage vSphere. It includes configuring, powering on and down virtual machines in vSphere, and creating and managing locally housed Windows 10 and other VMs in VMware Workstation.
Secure, isolated environments
Many choose to use VMware Workstation running on their Windows 10 host to run a Windows 10 VM used for another purpose such as a browsing VM, development, cybersecurity forensics, network management, etc. With the snapshot and other features provided by VMware Workstation, it allows quickly rolling your Windows 10 VM back to a known good state at any point.
VMware Workstation provides a robust feature set that connects your virtual machines to fit your environment needs from a networking perspective. By default, VMware Workstation creates the following networks in the Virtual Network Editor. These include a bridged network, Host-only, and NAT. As with VirtualBox, you can tweak the DHCP Settings.
Virtual Network Editor with VMware Workstation
After clicking the DHCP Settings button, you can configure the DHCP Settings with all the expected settings, including starting and ending address and lease time settings.
Customizing the virtual network DHCP settings in VMware Workstation
A really interesting ability that VMware Workstation provides is the ability for network condition simulation that allows simulating network conditions, including latency, packet loss, and even the bandwidth of your connection. The network condition simulation is a convenient tool to have access to for troubleshooting, development, and other purposes.
Having the ability in your Windows 10 development workstation or other VM to simulate network conditions is a great tool to allow development applications or testing processes and services over very slow links or other adverse network conditions. The network condition simulation is a feature not found in VirtualBox. However, VMware Workstation is a pay-for product. You can install and use VMware Workstation for 30-days in a trial period.
As mentioned earlier, nested virtualization is something that VMware Workstation does exceptionally well. Many in the community house their entire virtualization home lab off VMware Workstation running on either a workstation-class machine or a powerful laptop. It means you can set up your entire virtualization lab featuring nested hypervisors such as ESXi running child VMs with Windows client operating systems like Windows 10.
Configuring hardware virtualization in VMware Workstation for nested virtualization
VMware Workstation Player is a free version of VMware’s desktop virtualization platform that provides the ability to have both a graphical and command-line interface for running a single VM. It is meant for use cases where a single VM is needed to create a secure, isolated sandbox on a PC. It is commonly used in education environments as a free and easy way to learn more about IT and computer systems in general.
VMware’s enterprise hypervisor is arguably the most well-known hypervisor in the enterprise environment today. VMware has a long history in the world of virtualization. They pioneered the virtualization movement back in the early 2000s and have revolutionized the virtualization industry ever since. In its current form, the ESXi hypervisor represents many years in development and touts some of the most cutting-edge features compared to any other hypervisor available on the market.
VMware ESXi is a Type 1, bare-metal hypervisor that provides a complete set of features and capabilities needed in enterprise data centers. It is both a free product from VMware and a licensed software solution purchased with support and additional licensed features we will cover below.
Specifically, VMware markets the VMware ESXi free edition as vSphere Hypervisor. You can easily download the vSphere Hypervisor by signing up for a VMware account (free) and requesting the ESXi free hypervisor. If you have a dedicated physical host that you plan on using for virtualization learning, practice, running Windows 10, and other guest VMs in a dedicated fashion, this is a great option.
Downloading VMware vSphere Hypervisor 7.0
VMware touts the vSphere ESXi hypervisor as the “world’s smallest and most robust architecture.” There are a few limitations to note with VMware ESXi free. The restrictions for the free vSphere Hypervisor include the following:
- Virtual Machine vCPUs are limited to 8 vCPUs
- No VMware Support
- No vSphere Storage APIs are exposed
- No management using vCenter Server
The free version of ESXi will function essentially as a dedicated workstation or laptop that would run your Windows 10 or other virtual machines. Keep in mind that even though this is a Type 1 bare-metal hypervisor, you will not be able to do any fancy high-availability or resource scheduling between multiple nodes. These enterprise features require a vCenter Server in the mix. However, if you are looking at the list of hypervisors to use for the best virtual machine for Windows 10, VMware ESXi is arguably the “cream of the crop” among hypervisors out there.
Now, as mentioned, there are limitations with the free version of the ESXi hypervisor. However, if you want to have all of the enterprise features and capabilities for your Windows 10 and other workloads, you can step up to the paid version of VMware ESXi. With the latest licensed version of VMware vSphere ESXi 7.0 Update 1, you can now create virtual machines with a whopping 24 TB of memory and 768 vCPUs. What other enterprise features do you get with the paid version of vSphere ESXi?
- VMware High Availability (HA)
- VMware Distributed Resource Scheduler (DRS)
VMware High Availability (HA)
Let’s say you have a Windows 10 VM that is production critical, and you want to ensure it can withstand the failure of a hypervisor host. With the paid version of VMware ESXi and vCenter Server in the mix, you can configure a vSphere cluster. The vSphere cluster ensures that you have multiple hosts sharing a pool of resources. If a single host fails, VMware High Availability (HA) kicks in, and the virtual machine relocates to a healthy host remaining in the cluster.
Distributed Resource Scheduler (DRS)
DRS is a tremendously powerful feature found in the enterprise version of vSphere. With DRS, the resources in the vSphere cluster are automatically normalized across the available cluster resources. With DRS’s capabilities, virtual machines can be vMotioned across different hosts in the cluster depending on which host better satisfies the equation of a “happy VM” over the others.
In terms of networking capabilities, in both the free and paid version of ESXi, you get access to the vSphere Standard Switch (VSS), which provides robust networking capabilities out of the box. VSS features include VLAN trunking, the ability to create isolated switches, failover behavior, some light security features, etc. Those who have the Enterprise Plus license of vSphere or a vSAN license have access to the vSphere Distributed Switch (vDS). The vDS switch provides the most powerful and fully-featured virtual switch capabilities. With the vDS, you can automate and streamline your virtual networking configuration and centralize the management with the vCenter Server.
Viewing virtual networks configured for an ESXi host
VMware ESXi also provides the ability to run virtual machines using nested virtualization. It allows the ability to run virtual machines that are hypervisors and run child VMs running in the environment. Nested virtualization in ESXi is configured using the Hardware Virtualization – Expose hardware-assisted virtualization to the guest OS flag set on a per-VM basis on VMs running on top of ESXi. As a note, this setting is also available and configurable with the free version of ESXi.
Configuring the hardware virtualization setting for nested virtualization
Any way you slice it, VMware ESXi is an excellent hypervisor with world-class features used to host millions of workloads across myriads of data centers, both public and private. In its free form, it is still powerful but has limits to note. Licensing for vSphere ESXi and vCenter Server is not cheap, so ESXi free may provide all the functionality and features needed.
Microsoft has been playing catchup with VMware over the past several years in enterprise virtualization. Over the past several years, they have been working hard to advance the Hyper-V solution to incorporate the features and functionality that enterprise customers have longed for over the past several years. With the introduction of Windows Server 2019, Microsoft Hyper-V has become a fully-featured enterprise-class hypervisor that is genuinely ready for enterprise workloads.
Like VMware vSphere, Microsoft Hyper-V comes in a free and paid version. Hyper-V Server is the free version of Microsoft Hyper-V. Hyper-V Server, a Type 1 hypervisor, is a special-purpose operating system from Microsoft that is essentially Windows Server Core with the Hyper-V Role installed by default. When you install Hyper-V Server, you can customize and configure the server through the sconfig utility, which provides a pseudo-GUI interface in text format that is menu-driven for configuration. Afterward, you can use Hyper-V Manager on a management workstation or Windows Admin Center to manage the Hyper-V host.
With Hyper-V Server, there are limitations from the full-blown Windows Server installation with the Hyper-V Role added. For one, there are no licenses included with Hyper-V Server compared to Windows Server Standard with 2 VM instances and Windows Server Datacenter, unlimited VMs. Microsoft Hyper-V Server is a great platform, especially for running Linux virtual machines. However, there are no limits to running Windows guest VMs other than licensing. However, it is noted this is a consideration with any hypervisor platform unless running Windows Server 2019 with the Hyper-V Role installed.
There is yet another Hyper-V hypervisor to consider when you want to run Windows 10 or other virtual machines. It is the Hyper-V Windows feature for Windows 10.
Hyper-V Windows feature for Windows 10
When you install the Hyper-V Windows feature, this installs the Hyper-V feature in Windows and instantiates the Hyper-V hypervisor before the Windows 10 operating system. This process is how the Hyper-V Role is still considered a Type 1 hypervisor despite the appearance that it is running on top of the host operating system.
Microsoft makes a few things easier with Hyper-V on Windows 10, such as creating a default virtual switch for network connectivity, which is not the case with Windows Server Hyper-V. With Windows 10 Hyper-V, you get the “Quick Create” wizard that easily creates virtual machines. Think of Windows 10 Hyper-V functionally the same as VMware Workstation and VirtualBox.
VMware Fusion Pro and Fusion Player
The VMware Fusion Pro and Fusion Player products from VMware are the MacOS equivalent to VMware Workstation Pro and Workstation Player products for Windows and Linux and share the same basic features as mentioned above. It includes support for running VMs, containers, Kubernetes clusters, and interacting with VMware vSphere. With VMware Fusion Pro and Fusion Player, you can run Windows 10 on top of macOS and even run additional copies of MacOS in your Mac environment. Here is more information about VMware Fusion Pro and Fusion Player.
Best virtual machine for Windows 10 FAQ
Let’s answer the following commonly asked questions related to running Windows 10 inside a virtual machine.
Is there a virtual machine for Windows 10?
- Microsoft does provide VHDs for downloading Windows 10 as a virtual machine for use with Hyper-V. These can be converted to other formats, such as the VMDK, for use with VMware. Otherwise, Windows 10 virtual machines are created in the hypervisor of your choosing using the downloaded ISO from Microsoft.
Which is the best virtual machine?
- The best virtual machine may be subjective for most users. Windows users will have different needs than MacOS users, as an example. Others want to use virtual machines as an application on their host, while others may want to have a dedicated host running their virtual machine. It is difficult to crown a type of Windows 10 virtual machine as the best.
Is VirtualBox better than VMware?
- Both VirtualBox and VMware ESXi hypervisors provide great features. VirtualBox is a free Type 2 hypervisor that has long been used as a quick and easy virtualization platform providing a wide range of features and functionality. VMware ESXi free is a Type 1 bare-metal hypervisor that provides compelling features. However, to get the full enterprise data center virtualization features, you will need to purchase a vSphere ESXi license as well as a vCenter Server license. Again, better is hard to quantify. VMware ESXi is arguably the most powerful hypervisor on the planet. However, many will appreciate the ease with which VirtualBox can be installed, configured, and run virtual machines.
What is the best free VM software?
- VirtualBox takes the crown for the best free VM software. Based on the available features, great networking, nested virtualization, and the ease of providing virtual machines, it stands out among other free hypervisor solutions for running Windows 10 and other virtual machines.
Choose the best virtual machine for Windows 10 depends on your needs and use case. It also relies on which operating system you want to use for the host. If you are looking to use virtualized Windows 10 instances from time to time but do not need VMs constantly running, the Type 2 hypervisors mentioned such as VirtualBox, VMware Workstation, and VMware Fusion may be excellent choices. Windows 10 Hyper-V, which is a Type 1 hypervisor can also function in this way. However, if you are looking to run VMs continuously, you will want to consider VMware vSphere ESXi or Microsoft Hyper-V for this purpose.
