Below is a mostly paste'n'go Ceph recipe — apt clears the input buffer,
so it can't be pasted in its entirety.
I've tested it on a blank VM and it seems to work. It could be a little
tidier, e.g. currently logs will end up in /var/log/ceph.
I'm unsure about the test case as you have it above. The failure with
Openstack occurs when we try to attach a volume to a running instance,
not when the instance is started, so the test case probably needs to
simulate that more closely. With a working Ceph handy the test case can
now attach a volume and then perhaps poll "virsh dumpxml" for a while to
ensure it shows up.
I seem to recall "virsh attach-disk" being a sufficiently incomplete
mapping to "virsh attach-device" that it can't be used for RBDs. The
test case will probably have to construct a suitable XML fragment and
feed it to "virsh attach-device". Something like this should work:
<disk type='network' device='disk'>
<driver name='qemu' type='raw' cache='none'/>
<source protocol='rbd' name='rbd/blorp'/>
<target dev='vdz' bus='virtio'/>
</disk>
