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.
