If the VM fails or a disaster strikes the production site, the VM can be recovered to the original state with the help of the saved snapshot. Snapshots in VMware and Hyper-V not only work differently, but also have different names.
Administrators working in Hyper-V or VMware environment should be aware of how snapshot technology works so as to improve memory space management. The feature of change tracking lets you identify block-level changes that have occurred in the system. It is based on incremental backup technology, meaning that the initial backup of the VM is full, whereas in all consequent backups only the new data is backed up. CBT speeds up the backup process considerably and provides maximum efficiency.
Note that if you had been running a VM on Windows Server R2 or earlier versions, and later moved it to the host server with Windows Server , you should upgrade the VM to the latest version before backing it up. This can be done in the Hyper-V Manager. Both VMware and Hyper-V apply a variety of memory-management techniques. Some of the techniques used by VMware to achieve a high level of RAM optimization are presented below:. As you can see, VMware provides a wide variety of memory management techniques.
However, Hyper-V provides only one tool, called Dynamic Memory, which functions in the same way as the VMware Oversubscription feature. Dynamic Memory allows you to set up a specific amount of memory, memory priority, and other memory optimization settings on the basis of which Hyper-V then defines how much memory should be allocated to a particular VM.
The administrator has more freedom when operating with Dynamic Memory in Hyper-V than with VMware memory management techniques. Workload migration has long become a necessity when operating in a virtual environment.
Both VMware and Hyper-V have introduced their own tools which enable the migration of production workloads across the infrastructure. VMware vMotion is a part of VMware vSphere which enables the seamless migration of workloads between servers in almost real time. Also, with the VMware vSphere Distributed Resource Scheduler, you can schedule migrations to occur at a specific time, which allows you to automate workload migrations.
Hyper-V Live Migration is the migration tool designed for transferring a running VM or an application between physical hosts, without causing the system downtime. However, the implementation of Live Migration is much more complex than that of vMotion.
Before performing the workload migration, you need to set up Microsoft Failover Clustering on all physical hosts that will participate in the process and adjust network settings so as to ensure the seamless data transfer. You can read the full list of the supported OSes in the guest operating system installation guide. As for Hyper-V, the number of supported guest OSes is limited. Scalability of the virtual infrastructure should always be considered by organizations when choosing a hypervisor.
Therefore, when choosing between Hyper-V and VMware, consider your business needs and priorities, physical resources of your infrastructure, and the available budget. A virtual environment can be rather fragile. Thus, it needs to be securely protected against any malicious attacks or viruses. Both Hyper-V and VMware ensure security for your virtual environment with the help of various services and tools.
VMware vSphere 6. Moreover, data protection is guaranteed even during the workload migration. In this case, the feature of Encrypted vMotion is enabled, which allows you to protect data when it is moved between physical servers and even across a hybrid cloud environment. Guarded Fabric is a data-protection technique that lets you build a safe environment for VMs. The latest additions to the data protection system of Hyper-V are Windows Defender Advanced Threat Protection ATP , which allows to detect to cyber-attacks and respond to threats in advance with the help of machine learning, and Windows Defender Exploit Guard EG , which protects against ransomware attacks and reduces the attack surface of critical applications.
It is worth noting that vSphere 6. Hyper-V and VMware provide an opportunity to use a free version of their virtualization platforms.
This way you can see how the product works and what kind of benefits it provides. Depending on how many hosts have the software installed, you can identify the total number of cores for which licenses are required. Each license is a two-core pack. Note that the minimal number of cores which can be licensed is four, meaning that processors with one and two cores still would be assigned four cores.
Therefore, each server CPU should be assigned at least one processor license key. It is important to consider all aspects of a hypervisor, both its strengths and weaknesses. Then restart your system. Hyper-V virtualization will not start after the reboot, and you should find your performance returns to normal.
If you want to turn Hyper-V virtualization on again, use the following command:. Although the platforms use different names, Snapshots and Checkpoints are very similar tools.
They allow youto take an image of the virtual machine in its current status. The image preserves the virtual machine, allowing you to return to that specific moment. Each hypervisor allows you to drag and drop files between the host and guest operating system. VirtualBox and VMware Workstation Player both use seamless mode to integrate the virtual machine environment into the host operating system.
Seamless mode strips away the additional virtual machine window and menus, making it feel as if the guest operating system is part of the host. Each hypervisor supports encryption of one kind or another. So long as your hardware can run the guest operating system without destroying the host in the process, you can use the free virtual machine software. There are workarounds for Windows 10 Home users desperate to use Hyper-V on their hardware.
But those people may as well use one of the free alternatives rather than shoehorn a solution. Windows 10 Hyper-V has some limitations regarding guest operating systems. It does not support macOS. Skip to content.

VMware Workstation – Wikipedia
Decide on which application to use for your virtualization work, it all depends on what type of work and Virtual Machines you will create and for what purpose. Depending on those needs, select the best tool that fit your requirements. Always bear in mind that one you can use with a free license free for personal non-commercial use. Business and non-profit use is considered commercial use and the other needs a paid license. As we showed in this article, Workstation Player is more for basic virtualization tasks, and Workstation Pro is more for advanced and expert virtualization work with some more powerful features to extend virtualization tasks to a hypervisor level.

ReFS can detect and promptly fix data corruptions. This can be done online, thus causing no volume downtime. To ensure efficient performance within the virtual environment, both VMware and Hyper-V provide a set of system services and tools which can be easily installed.
With VMware vSphere, you can install VMware Tools, which is a set of utilities and drivers used for seamless integration between the host and the guest ESXi servers, and efficient management of the VM data. VMware Device Drivers provides a set of drivers for installation, which can enhance mouse operations, networking performance, and the quality of sound and graphics. Installing VMware Tools offers multiple benefits: enhanced graphics performance, high-level synchronization between the host and guest file systems, and shared access to files and folders within the virtual environment.
Hyper-V provides the opportunity to install Microsoft Integration Services, which helps in performing various tasks and solving reoccurring issues. Moreover, you can easily edit and manage the created packages in the Business Intelligence Development Studio BIDS with the help of its user-friendly interface. This feature enables the upgrading of a catalog database, which stores and monitors all database packages in the system. Upgrading the catalogue database is necessary for avoiding any issues which might occur if the version in use is older than that of SQL Server.
Snapshot technology allows you to capture a point-in-time copy of a VM and all the data that it contains. If the VM fails or a disaster strikes the production site, the VM can be recovered to the original state with the help of the saved snapshot. Snapshots in VMware and Hyper-V not only work differently, but also have different names.

VMware vSphere 6. Moreover, data protection is guaranteed even during the workload migration. For example, the VirtualBox wizard has you create a basic virtual machine for which you edit the settings afterward, but it does offer some suggested values for specific virtual machine types.
Whereas, the VMware Workstation Player wizard allows you to customize settings during the virtual machine creation process. The performance of a virtual machine relates to the hardware you use to run it.
With virtualization, hardware is king. Furthermore, the virtual machine you use makes a huge difference. The performance deficit is most noticeable when you switch to VMware Workstation Player. Running the same guest operating system on the same hardware shows that the VMware Workstation Player is a smoother, slicker experience.
So, where does Hyper-V fit into all of this? The Hyper-V installation of Lubuntu performed well and was noticeably smooth. It is important to note that some Windows 10 Hyper-V users report performance issues in other areas once they enable Hyper-V on their system. If you feel Windows 10 Hyper-V is affecting your gaming performance or otherwise without a virtual machine environment running , you can use a command to switch Hyper-V virtualization services off. Type command in your Start Menu search bar and select Run as Administrator.
Then input the following command:. Then restart your system. Hyper-V virtualization will not start after the reboot, and you should find your performance returns to normal. If you want to turn Hyper-V virtualization on again, use the following command:.
Although the platforms use different names, Snapshots and Checkpoints are very similar tools. They allow youto take an image of the virtual machine in its current status.
