Hi,
We had a failure for test 006_migrations.migrate_vm on master.
There was a libvirt disruption in the migration src and after that vdsm
reported the migration as failed because the vm already exists which
makes me suspect a split bran case.
The patch reported has nothing to do with this issue and I think we
simply stumbled on a race condition which can cause a split brain.
Please note that there are several metrics related issues reported in
vdsm logs as well.
