One of the most popular comparisons on IT Central Station is Hyper-V vs KVM.
People like you are trying to decide which one is best for their company. Can you help them out?
What is the biggest difference between Hyper-V And KVM? Which of these two solutions would you recommend to a colleague evaluating server virtualization software and why?
Thanks for helping your peers make the best decision!
Microsoft Hyper-V:
Microsoft introduced its hypervisor in 2008, and has continued to release new versions along with the new Windows servers. Hyper -V helps one expand or establish a private cloud environment, promotes effective hardware utilization, improves business continuity and makes development and testing more efficient. We have discussed some features for Windows Server 2019 here.
Features:
Persistent memory support.
Shielded VM updates.
Simple Two-Node clusters.
ReFS Deduplication.
Storage Spaces Direct improvements.
Windows Admin Center.
Encrypted subnets.
KVM (Kernel-based Virtual Machine):
KVM is a complete virtualization infrastructure solution. Kernel-based Virtual Machine turns Linux kernel into a hypervisor. A part of Red Hat Virtualization suite, it was merged into the Linux kernel mainline in kernel version 2.6.20.
Here is an overview of the features of KVM:
Scalability.
Overcommit resources.
Disk I/O throttling.
Hot plug of virtual resources.
Low cost virtualization solution.
Use API.
Live Migration & Storage Migration.
Assign any PCI device to virtual machines.
Container support.
Disaster Recovery support.
KVM is very fast & very stable & low cost.
The tooling around Hyper-V is more advanced than around KVM,
Speed wise, setting up and managing the virtual machines appear easier in KVM than in Hyper-V especially for remote servers on slow connections.
Best regards.
