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. I created a simple machine booting from a volume based off the Ubuntu 14.04.1 cloud image for testing. Using Horizon, I can move this VM from host to host, but when I try to Live Migrate it from one baremetal host to another, I get an error message ?Failed to live migrate instance to host ?node02?". The only related log entry I recognize is in the controller?s nova-api.log: 2014-09-25 17:15:47.679 3616 INFO nova.api.openstack.wsgi [req-f3dc3c2e-d366-40c5-a1f1-31db71afd87a f833f8e2d1104e66b9abe9923751dcf2 a908a95a87cc42cd87ff97da4733c414] HTTP exception thrown: Compute service of node02.baremetal.clusterb.centerdevice.local is unavailable at this time. 2014-09-25 17:15:47.680 3616 INFO nova.osapi_compute.wsgi.server [req-f3dc3c2e-d366-40c5-a1f1-31db71afd87a f833f8e2d1104e66b9abe9923751dcf2 a908a95a87cc42cd87ff97da4733c414] 10.102.6.8 "POST /v2/a908a95a87cc42cd87ff97da4733c414/servers/0f762f35-64ee-461f-baa4-30f5de4d5ddf/action HTTP/1.1" status: 400 len: 333 time: 0.1479030 I cannot see anything of value on the destination host itself. New machines get scheduled there, so the compute service cannot really be down. In this thread Travis http://lists.ceph.com/pipermail/ceph-users-ceph.com/2013-March/019944.html <http://lists.ceph.com/pipermail/ceph-users-ceph.com/2013-March/019944.html> describes a similar situation, however that was on Folsom, so I wonder if it is still applicable. Would be great to get some outside opinion :) Thanks!
