Hyper-V vs KVM comparison

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 (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko.
