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.
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:

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.
