@forest and vbox was specifically written to support it iirc

Didn't Vbox actually used to use ring 2 as well?

Or was that another hypervisor?

Possibly. I have not done much 'fun' virtualization since my late 20s alas. Used to mess with any os I could get my paws on

But probably

I'm not a fan of Virtualbox, tbh. I prefer QEMU-KVM

Lol. Wasn't an option back then.

Or wasn't aware of it

Currently if I need to run a full fat vm, kvm is my preference

Do you use QEMU as the frontend on its own or virt-manager?

Virt manager

Ah. Never been a fan of plain virt-manager, but I'm sure it does help workflow for some people (just not my style).

Lol. I tend to try to spend as little time on basic setup as possible and as much doing as possible

Virt manager isn't 'cool' but it gets me up and running

Most of what I run is lxc containers tho
