Those type of features would benefit Hyper-V.""We'd like a template feature to help deploy VMs quickly.""It would be nice if they provided a free management console that we could use to manage all of the hosts for no additional fee.""The interface could be more user friendly. In addition, the documentation and security could use improvement.""The Hyper-V management console could be improved to make it easier. It should be a little bit more granular. Various virtual switches could also be improved to make virtual desk management slightly better. The replication could be improved slightly. The checkpoints or snapshots could be improved to make it a bit more transparent to the user.""The solution could improve by having virtual restore."

More Hyper-V Cons →

"Its resource usage can be improved.""Lacks high availability across clusters as well as support for Apache CloudStack.""The stability of this solution is less than other products in the same category.""One problem I have is that it's not very scalable when it comes to resizing the VM disk dimensions. For example, if you have initially set a virtual drive to 10 GB and you want to upgrade it to 15 GB, it's not that easy.""The initial setup of this solution is more difficult than some of the competing products and it could be improved.""The virtual manager and the graphical QEMU for KVM need some improvement.""Monitoring and resolution could be improved.""The speed is around thirty percent slower than another competitor. This would be something to work on."

  • "I do not have any comments about pricing or licensing of the product."
  • "Microsoft recently tacked on a higher price for their software to use the storage migration in the Storage Spaces Direct array. That was just terrible."
  • "The pricing isn't too bad, because you can do the bare metal hypervisor, and it is pretty fair. Other competitors are more expensive."
  • More Hyper-V Pricing and Cost Advice →

  • "​It is free and can be run from your laptop, if needed, unlike VMware.​"
  • "It is cheaper than other competitors like VMware or Hyper-V."
  • "It is cheaper than other solutions out there on the market."
  • "This solution came with the Linux license."
  • "This solution is an open-source, free platform with paid support."
  • "It is free for everyone."

    Overview

    Hyper-V is a hardware virtualization tool that allows users to create virtual computer environments with multiple operating systems on a single physical server. Each virtual machine has computer parts, such as memory, processor, storage, and networking, and acts like a standard computer - running its own operating system and software programs. Each component of the virtual machine can be configured to meet your specific requirements.

    Hyper-V creates a cost-effective, stable, and productive server virtualization environment by running multiple operating systems, such as Windows, Linux, and more, in parallel on one machine or server. Each virtual machine runs in its own isolated space, which means you can run many virtual machines simultaneously but independently of each other. This helps prevent problems such as a crash affecting the other workloads and enables different users to separately access various systems.

    Benefits of Hyper-V

    • Simplify application testing: With Hyper-V you can easily add and remove operating systems from your virtual machines, enabling you to run and test your applications on each of them all from one single computer.

    • Minimize resource usage and scalability: Virtual machines are easier to manage than physical hardware and less expensive. You can also maximize your server use by allocating its resources more efficiently than you can with physical hardware alone.

    Hyper-V key features:.

    • Replication and migration: Hyper-V can replicate virtual machines for backups onto different sites. Hyper-V also provides a migration tool for moving a virtual machine from one Hyper-V host to another without causing any downtime.

    • Remote connection: Hyper-V’s remote connectivity tool allows administrators to remotely access a virtual machine.

    • Security: Hyper-V keeps virtual machines secure from malware attacks, unauthorized access, and data breaching attempts.

     Reviews from Real Users

    Hyper-V stands out among its competitors for a number of reasons. Several major ones are its flexibility, its replication capabilities, and the fact that its virtual machines utilize a small amount of resources..

    Liam L., the owner of a tech services company, writes, “It is actually very low on resources. It doesn't use many resources. It is also very easy to tailor. You can change things like the amount of memory and storage on the fly. It is very stable and reliable. I like its replication feature, which is very good. It is also very easy to move the virtual machines across push servers without any difficulty. Its performance is also very good. Now with this pandemic, a lot of workers are working from home. A lot of workers have been using laptops as their desktop computers, and they would remote into a virtual PC. There is no difficulty, and they can't tell the difference between this and the real one. It is much easier to manage.”

    Kevin E. an IT director at Homeland Technology Group, LLC, notes, “We've probably seen a 50 percent speed increase on our SQL server. Hyper-V has also significantly reduced our downtimes with faster boot-up and reboot. If we have to reboot a server, there is maybe two or three minutes of downtime. When we were on a bare-metal server, it could be five to ten minutes due to the total boot time.”

    KVM stands for Kernel-based Virtual Machine, which is an open-source virtualization technology that is embedded in Linux. KVM allows users to seamlessly transform their Linux system into a hypervisor that, in turn, will enable a host machine to run numerous, isolated virtual environments or virtual machines (VMs).

    KVM is part of Linux. Users with Linux 2.6.20 or newer already have KVM. As KVM is already a component of the current Linux code, it automatically improves with every new Linux fix, feature, or upgrade. So KVM users are always current and up to date.

    KVM automatically transforms Linux to a type -1 (bare-metal) hypervisor. All hypervisors need operating system components, such as a process scheduler, I/O stack, device drivers, memory manager, and more, to run a VM. KVM already has these components embedded, as it is part of the Linux kernel. Each VM is generated as a basic Linux proces,s which is maintained by the standard Linux scheduler, with dedicated hardware such as a graphics adapter, memory, disks, network card, and CPUs.

    KVM Key Features:

    KVM has many valuable key features. Some of its most useful features include:

    • Storage: KVM has the ability to use any storage protocol supported by Linux, including network-attached storage (NAS) and some local disks. Multipath I/O can be utilized to provide redundancy and improve storage. Disk images use thin provisioning, ensuring storage is used on demand. KVM is also able to use shared file systems, enabling VM images to be shared on multiple hosts.
    • Hardware: KVM is able to use a vast number of Linux-certified supported hardware platforms. As hardware vendors routinely contribute to kernel improvement, the most up-to-date hardware features are generally quickly added to the Linux kernel.
    • Memory: KVM effectively utilizes the memory management features of Linux, such as kernel same-page emerging and non-uniform memory access. The memory of a VM can easily be switched, supported by large volumes for improved performance, then backed by a disk file or shared.
    • Migration: KVM actively supports live migration so users have the ability to move any running VM between physical hosts with no downtime.
    • Security: KVM uses a blend of secure virtualization (SVirt) and security-enhanced Linux (SELinux) for improved VM security and isolation. SELinux determines security boundaries surrounding VMs. sVirt expands SELinux’s processes, permitting Mandatory Access Control (MAC) security to be used for guest VMs and preventing any manual labeling issues.

    Reviews from Real Users

    “The most helpful aspect of KVM is the fact that the interface is so minimal. It includes just what you need to set up the VMs and manage them, and it's very simple to do so. KVM, as a native virtualization solution, is a complete and fully adequate system for small businesses that need to reduce costs, and also to make maintenance easier. “ - Georges E., Business Engineer and Consultant at All-Tech

    “The most valuable feature of KVM is the hypervisor environment and how we can configure it with ease. Additionally, the interface is intuitive.” Sonu S., Senior Solution Architect at Micro Focus
