Cons
"The technical support is good but it could improve by being faster.""Security, computing balance, and taking snapshots could be improved. Features like DRS and memory ballooning could be added.""Hyper-V systems need a lot of admin effort because security updates and monthly updates require rebooting after the update.""If you have a bigger implementation, you need more tools to coexist with many, many features that are not present in the base Hyper-V.""Failure capabilities are insufficient for disaster recovery.""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 is heavily reliant on Microsoft's active directory for authentication, for coordination between nodes. Therefore, it inherits all the issues that are within the active directory.""It's not completely stable because your stack becomes bloated."

More Hyper-V Cons →

"One thing that maybe could be improved is making it easier to scale. It needs to be more clear on how to scale the storage space for virtual machines.""Business continuity features need to be added.""Technical support could be better. In the next release, I would like to see an improved user interface and dashboard. This type of improvement will make it easy or help our engineers understand the solution from a requirement point of view.""In our setup, we do not have any dashboards or orchestration, and it is hard to manage. We have 25 gig network cards, but the software driver we have only supported 10 gigs.""Monitoring and resolution could be improved.""Lacks high availability across clusters as well as support for Apache CloudStack.""There are some issues with the graphics and some software that is very complex.""I have previously used VMware and KVM is easier to use. However, they both have their strengths depending on their use cases. They are mostly equal. One of VMware's advantages is it has better support."

Pricing and Cost Advice
  • "Microsoft Hyper-V is not expensive and is easy to set up."
  • "This is a fairly expensive product because it balances the needs of security."
  • "If you have the standard edition of Windows server then with each copy of the operating system, you have two virtual machines for free."
  • "Because we're an NGO or a charity, we get discount rates from Microsoft. The costs are not astronomical for us. To give you an example, Office 2019 would only cost 30 or 45 for us. We tend to use the on-premises version rather than the cloud version. The reason is that the subscription service works out more expensive after a few years than the on-premise version. We're not worried about having the bleeding edge stuff. We just want it to be functional."
  • "Hyper-V is cost-effective and is a one-time purchase. Microsoft has multiple licensing options available, such as a subscription model and an outside purchase model that customers can choose as per their requirements."
  • "There is a license required for this solution. I would recommend purchasing the support."
  • "There is a perpetual license to use the solution and there are additional fees for support."
  • "There is a license required to use Hyper-V and there are bundle packages you can purchase making it cheaper than other solutions, such as VMware. Additionally, if there is a lot of guest OS that requires Windows, then Microsoft becomes cheaper."
  • More Hyper-V Pricing and Cost Advice →

  • "It is free for everyone."
  • "The price is fair compared to others. But in our local market, it's a problem to get budget approval from management. That's why they are trying to get those products so we can give them the price benefit. But if you consider the international market or other products, it's sometimes better than their price."
  • "We had some problems with the licensing."
  • "KVM is priced reasonably."
  • "There is no cost involved in the use of KVM, as it is open source."

    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
