Title:
live-migration fails on shared storage with "Cannot block migrate"
Status in OpenStack Compute (nova):
Expired
Bug description:
Kilo RC from Ubuntu Cloudarchive for trusty. Patches
https://review.openstack.org/174307 and
https://review.openstack.org/174059 are applied manually without which
live-migration fails due to parameter changes.
KVM, libvirt, 4 compute hosts, a 9 host ceph cluster for shared storage.
Newly created instances work fine on all computes. When initiating live-migrate
either from Horizon or from CLI, status switches back from MIGRATING very fast
but VM stays on original host. Message
MigrationError: Migration error: Cannot block migrate instance
53d225ac-1915-4cff-8f15-54b5c66c20a3 with mapped volumes
is found in log of compute host.
Block-Migration option is explicitly not set, setting it for a try
causes a different error message earlier.
