Hi,
I just tried to start a VM with libvirt with the following disk:
<disk type='network' device='disk'>
<driver name='qemu' type='raw' cache='none'/>
<source protocol='rbd' name='rbd/8489c04f-aab8-4796-a22a-ebaa7be247a7'>
<host name='31.25.XX.XX' port='6789'/>
</source>
<target dev='vda' bus='virtio'/>
</disk>
That fails with: "Operation not supported"
I tried qemu-img:
qemu-img info
rbd:rbd/8489c04f-aab8-4796-a22a-ebaa7be247a7:mon_host=31.25.XX.XX\\:6789
Same result.
I then tried:
qemu-img info
rbd:rbd/8489c04f-aab8-4796-a22a-ebaa7be247a7:mon_host=31.25.XX.XX\\:6789:auth_supported=none
And that worked :)
This host does not have a local ceph.conf, all the parameters have to
come from the command line.
I know that recently auth_supported defaults to "cephx", but that now
break the libvirt integration since it doesn't set auth_supported to
explicitly none when no auth section is present.
Should this be something that gets fixed in librados or in libvirt?
If it's libvirt, I'll write a patch for it :)

Thought about it, this is something in libvirt :)

Just did so, very simple patch:

libvirt 0.9.13 just got out. The good news is that the RBD storage pool
is in this release, but the patch above did not make it in time.
We'll have to wait for 0.9.14 to get that one in.

The patch just made it into libvirt:
http://libvirt.org/git/?p=libvirt.git;a=commit;h=ccb94785007d33365d49dd566e194eb0a022148d
You will need this libvirt patch if you are going to run RBD without
cephx enabled
