KVM+QEMU+libvirt seems to be the way to go. What are you going to use instead? VMware?

VMware price hikes? Between 800 and 1,500%: https://www.theregister.com/2025/05/22/euro_cloud_body_ecco_...

this isn't really related but anyone else found VirtualBox basically unusable these days? Every linux distro I tried crashes or hang in a bizarre way and it's impossible to make the autoresize of the desktop work.

Hyper V on windows is fine
