[Qemu-devel] [Bug 1314293] [NEW] screendump with qxl + spice shows stale data

[Cole Robinson]

Public bug reported:

The monitor 'screendump' command returns stale data for VMs using qxl +
spice. If you perform multiple screendumps, screendump #N will show
roughly the display from the time screendump #N-1 was taken. This
affects 'virsh screenshot' and libvirt screenshot APIs by association.

Gerd explains that new monitor commands/infrastructure is likely
required to handle this correctly:
