Hi, To ensure if compute-service are UP you should verify output of 'nova service-list'. You can verify compute's log on source & destination and your NTP sync. By default Openstack doest'nt allow live-migration, you need to modify live_migration_flag on nova.conf and add listen support to libvirt. I use the same setup as you, but on Ubuntu12.04 (package are the same) and live-migration works perfectly. Good luck. --------------- Le 25/09/2014 17:34, Daniel Schneller a ?crit : > Hi! > > We have an Icehouse system running with librbd based Cinder and Glance > configurations, storing images and volumes in Ceph. > > Configuration is (apart from network setup details, of course) by the > book / OpenStack setup guide. > > Works very nicely, including regular migration, but live migration of > virtual machines fails.
