Bug Description
In environment of usage SAN multipath LUNs and boot-from-volume VMs, os-brick cannot successfully detach LUN from compute host while nova [live-]migrates the VM if LUN has partitions. These partitions are locked by 'kpartx' service, so 'multipathd del map' operation fails.
We have to add "skip_kpartx yes" to the "defaults" section of multipath.conf config file to prevent kpartx scanning of the mpath devices.
