[vfio-users] Linux-on-Linux desktop

[Jiri 'Ghormoon' Novak]

Hello,

I've got very similar setup on my laptop, one VM with passed in GPU that
does X and desktop environment, a lot of containers and other VMs around
on the internal network.
I have discrete radeon GPU though, I've not personally tried any other.

Also have a look at QubesOS, that one has idea of AppVMs, where
applications are on separate VMs. It's based on Xen though. I wanted to
be able to pass in the only GPU though to be able to switch the X VM for
a windows one for gaming, so I went the LVM + LXC way instead. The
downside there are less premade tools, so you do some scripting yourself.

Regards,
Gh.
