Title:
--copy-storage-all failing with qemu 2.10
Status in QEMU:
New
Status in libvirt package in Ubuntu:
Confirmed
Status in qemu package in Ubuntu:
Confirmed
Bug description:
We fixed an issue around disk locking already in regard to qemu-nbd
[1], but there still seem to be issues.
$ virsh migrate --live --copy-storage-all kvmguest-artful-normal

Given the timing it seems that the actual copy now works (it is busy ~10
seconds on my environment which would be the copy).
Also we don't see the old errors we saw before, but afterwards on the actual
take-over it fails.
Dmesg has no related denials as often apparmor is in the mix.
Need to check libvirt logs of source [2] and target [3] in Detail.
