Your procedure appears correct to me. Would you mind re-running your
cloned image VM with the following ceph.conf properties:
[client]
rbd cache off
debug rbd = 20
log file = /path/writeable/by/qemu.$pid.log
If you recreate the issue, would you mind opening a ticket at

Jason,
Thanks for the reply. Recreating the issue is not a problem, I can
reproduce it any time.
The log file was getting a bit large, I destroyed the guest after
letting it thrash for about ~3 minutes, plenty of time to hit the
problem. I've uploaded it at:
http://paste.scsys.co.uk/468868 (~19MB)
It looks like your libvirt rados user doesn't have access to whatever
pool the parent image is in:
librbd::AioRequest: write 0x7f1ec6ad6960
rbd_data.24413d1b58ba.0000000000000186 1523712~4096 should_complete: r = -1
-1 is EPERM, for operation not permitted.
Check the libvirt user capabilites shown in ceph auth list - it should
have at least r and class-read access to the pool storing the parent
image. You can update it via the 'ceph auth caps' command.
