.QEMU process failure A paused instance that uses local storage cannot be live migrated more than once. The second migration causes the QEMU process to crash and nova puts the instance to ERROR state. *Workaround*: if feasible, unpause the instance temporarily, then pause it again before the second live migration. It is not always feasible to unpause an instance. For example, suppose the instance uses a multi-attach cinder volume, and pause is used to limit the access to that volume to a single instance while the other is kept in paused state. In this case, unpausing the instance is not a feasible workaround.
