No snapshot possible with virtio-gpu activated

[feuerkogel1]

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.

Hi
  You should find in current qemu that virtio-gpu migrates unless you've enabled the virgl 3d graphics
code. WHat version of the qemu package are you using? If it's old then I suggest you open a debian
bug against it.

Hello,

I'm using Qemu-version "1:2.6+dfsg-3" together with virt-manager-version
"1:1.4.0-3: all", as I've written, out of the regular
Debian-testing-repository (Stretch)...

[Expired for QEMU because there has been no activity for 60 days.]

I also have this problem, with the 3D acceleration enabled, it would be great if the situation improves as the VM often not stable after the host restores from sleep state.
