Hi,
Just trying to place in maintenance mode for a version upgrade, and
one VM fails to migrate. The other 20-odd move over successfully. In
/var/log/libvirt/qemu/, the VM's log on the source reports:

Hi,
it seems either qemu issue or misconfiguration. To investigate, we need
more data; so could you please share:
1. the domain XML (virtsh -r dumpxml ...) and/or the qemu command line
of the affected VM, on the source side
2. the version of QEMU and libvirt that you are running
Thanks and bests,
