Just for posterity, my ultimate solution was to patch nova on each
compute host to always return True in _check_shared_storage_test_file
(nova/virt/libvirt/driver.py)
This did make migration work with "nova live-migration", with one
caveat. Since Nova is assuming that /var/lib/nova/instances is o

The root disk (/var/lib/nova/instances) must be on shared storage to run

I would argue that it is on shared storage. It is an RBD stored in Ceph,
and that's available at each host via librbd.

You should be able to run block migration (whi

The root disk (/var/lib/nova/instances) must be on shared storage to
run the live migrate. You should be able to run block migration (which
is a different form of the live-migration) that does not require shared

Hey folks,
I'm wondering if the following is possible. I have OpenStack (Folsom)
configured to boot VMs from volume using Ceph as a backend for Cinder and
Glance. My setup pretty much follows the Ceph guides for this verbatim.
I've been using this setup for a while now, and it's all been really
