Created attachment 486882 [details] vdsm source and destenation logs Description of problem: during scale testing, *failed migration of a vm to destination host that runs 90 vms, finish with split brain. * Failed migration - libvirt daemon was restarted during that operation on source host. Flow: - destination host runs 90 vms - call migrate on source - migration starts - 5-10 seconds later - /etc/init.d/libivrtd restart - connection to libvirt is broken - vdsm takes it self down - on destination server, call destroy is initiated, but fails due to operation time-out, vm runs on destination server in paused state. - on source server, vdsm performs vm recovery, and runs the vm. result: split brain. vdsClient -s 0 list table: destination host: 4afaa2bb-d570-4ae4-964a-f19507ca786b 73182 FC-0-30 Paused* source host: 4afaa2bb-d570-4ae4-964a-f19507ca786b 79552 FC-0-30 Up Versions: -vdsm-4.9-55.el6.x86_64 -libvirt-0.8.7-13.el6.x86_64 attached source and destination vdsm logs.
