Bug#941576: qemu: Cant use virtio-gpu with some hardware
Thans for reply and sorry for the wrong link. the correct patch link is here.And it can diretly used in debian qemu src. https://src.fedoraproject.org/rpms/qemu/blob/35213eae677b3a6a98ef2f048ca72fe38d61e2fc/f/0011-seccomp-don-t-kill-process-for-resource-control-sysc.patch I have disable secomp on libvirt config file, but when I start virt-manager it not work.May gui client lile virt-manager and gnome-boxes force to use secomp. It will be helpful if the patch can be added in next debian point release.

If that's the case, just disable seccomp on the guest using virtio-gpu and it should work. Seccomp has very little value for qemu since majority of syscalls are allowed anyway, but it has quite significant impact on maintenance, as you can see in this very issue. Thanks, /mjt
