There are two kinds of live migration, with shared storage and without shared storage. If you don't have shared storage (like CEPH or glusterfs or NFS) you need to pass in the --block-migrate flag to manually copy the volumes across. (It can be slow.)
For info on doing this with CEPH: http://ceph.com/docs/master/rbd/rbd-openstack/ Gluster: http://www.gluster.org/wp-content/uploads/2011/07/Gluster-Openstack-VM-storage-v1-shehjar.pdf In general: http://docs.openstack.org/admin-guide-cloud/content/section_configuring-compute-migrations.html http://docs.openstack.org/admin-guide-cloud/content/section_live-migration-usage.html On Wed, Jun 10, 2015 at 5:40 AM, Abhishek Talwar <abhishek.tal...@tcs.com> wrote: > Hi Folks, > > > I have done a *multinode Kilo installation (with controller node, network > node, 2 compute nodes)*.
