[Qemu-devel] [Bug 1617385] [NEW] No snapshot possible with virtio-gpu activated

[feuerkogel1]

Public bug reported:

I'm using "Qemu" and "Virtual Machine Manager" on Debian-8-Stretch -
both newest versions out of the Debian-testing-repository (state
26.08.2016).

If I try to save a virtual machine, it fails and I'll get the following
error:

libvirtError: internal error: unable to execute QEMU command 'migrate':
State blocked by non-migratable device '0000:00:02.0/virtio-gpu'

This only happens, if I chose "Virtio" as graphics-driver (no matter if
I use "Spice" or "Vnc" as Server by the way). If I switch to any other
driver (Cirrus, Qxl, Vga, VMvga...) there is no problem to take a
snapshot and save the virtual machine.

Unfortunately "virtio-gpu" (together with "Spice-Server") is the only
driver that provides proper working/running my virtual machines on my
PC.
