On my machine I am able even to run even windows 10 nested (mostly for fun, don't need it), I can play (a bit slow but works) some linux games in nested VM, with virtio-gpu on top of virtio-gpu, and I was even able to run a win98 VM nested on KVM, and it works as good as it works non nested (has bunch of issues that probably will never get fixed sadly). -- You are receiving this mail because: You are watching the assignee of the bug.
