Im thinking to avoid oracle virtualbox, not sure how many options there are on linux but iv’e heared about qemu, kvm, etc. I want to setup a whonix workstation and gateway.
I had the same question a while ago:
https://discuss.cachyos.org/t/which-vm-solution-do-you-people-prefer/20175
I still haven’t started that topic, though 
so much to do on Cachy.
I see why literally anyone keeps saying, read the wiki!!!
Who would have thought reading can be helpful…
