Could you please expand on what you're meaning by "suspended"?
Suppose you're talking about guest's kernel suspension. There was a
discussion on [1] RE a need to use `x-pcie-pm-no-soft-reset=true` option
to avoid virtio-gpu resetting across S3 suspend-resume. This option
works with virtio-vga, but not with virtio-vga-gl device where VM hangs
on startup. So currently S3 doesn't work for virgl and needs further fixing.
