Public bug reported:
[Impact]
* Windows VMs BSOD when restoring from QEMUfile or during live migration if
the virtio balloon stats polling is enabled.
* Affected version: 1:2.5+dfsg-5ubuntu10.14 (xenial)
[Test Case]
* Install a Windows VM with virtio balloon drivers
* Start the VM and enable stats polling [1]
* Save the VM to savefile [2]
* Restore the VM [3]
* Enable stats polling [1] and VM will BSOD
QMP examples:
[1]
{"execute":"qom-set","arguments":{"path":"//machine/i440fx/pci.0/child[7]","property":"guest-stats-polling-interval","value":10}}
[2] {"execute": "migrate", "arguments": {"uri":"exec:gzip -c >
/storage/cases/VM/savefiles/testVM3save.gz"}}
[3] {"execute":"migrate-incoming","arguments":{"uri":"exec:gzip -c -d
/storage/cases/VM/savefiles/testVM3save.gz"}}
[Other Info]
* This has been fixed upstream with commit
