i think i know wich thread you mean, and they advised you to upgrade
however, i'm already running

here is the log from the latest try:
task started by HA resource agent

May 12 12:10:33 ERROR: migration finished with problems (duration
TASK ERROR: migration problems
i also saw the task starting the vm on the new node and starting the
migration tunnel, which succeeded.
as for storage:
we are using ceph storage for the VMs
just for the record:
i reran some test just now:
* offline migration works (i have a test vm that i could use for
* even though i got an error yesterday, it worked just now for a
freshly booted VM
i still would like to find a way that does not involve shutting down
all VMs to get migration working again...the next possible time for
that would be at some point end of next week most likly...

yes i know, i just saw it...however i really don't think non-running
kernels are the problem here...
