Free virtualization host for Linux?

Question

linux

Good day to all!
There is a small industrial server, I want to deploy a virtualization host on Linux on it.
Actually, the main requirement is the ability to create virtual networks.
ESxi costs money, so it's not an option yet.
What is now relevant for Linux from open source to virtualization?

Answer 1

I recommend Proxmox. The ready-made distribution kit is easily deployed out of the box and is very convenient to use. Web muzzle out of the box and very functional

Answer 2

Proxmox is not bad at implementing the role of not even a single server, but at the cluster level.

Answer 3

WebVirtCloud
