I think the section headed "Block Migration" is incorrectly nested under
"XenServer", or there should also be a "Block Migration" section under
"KVM-Libvirt". Also missing are the nova flags you should have:
block_migration_flag=VIR_MIGRATE_UNDEFINE_SOURCE, VIR_MIGRATE_PEER2PEER,
VIR_MIGRATE_NON_SHARED_INC, VIR_MIGRATE_LIVE
That, along with the other changes mentioned in the section (obviously
excluding shared storage), should give you live block-migration.
