Hello,
Current version adding 'auth_supported=none' at the end of disk path
and failing to do an authentication with specified cephx key:
<source protocol='rbd'
name='rbd/vmxxxxxxxxx:id=qemukvm:key=[cut]==:auth_supported=cephx'>
<host name='10.0.0.13' port='6789'/>
<host name='10.0.0.10' port='6789'/>
<host name='10.0.0.17' port='6789'/>
</source>
results to:
0.10.1

file=rbd:rbd/vmxxxxxxxxx-YSG:id=qemukvm:key=[cut]:auth_supported=cephx:auth_supported=none:mon_host=10.0.0.13\:6789\;10.0.0.10\:6789\;10.0.0.17\:6789,if=none,id=drive-virtio-disk0,format=raw,bps_rd=80000000,bps_wr=40000000,iops_rd=400,iops_wr=200

In ceph-devel I have mentioned incorrectly that both strings are the
same due to incorrect grep statement, so all that needs to be fixed is
an wrong parameter at the end.
Thanks!

If you use the libvirt secret explicitly instead of passing it through
the name like that, libvirt >= 0.10 will set auth_supported=cephx if
you specify the secret, and auth_supported=none if you don't specify the
secret. For example:
secret.xml:
<secret ephemeral='no' private='no'>
<usage type='ceph'>
<name>client.qemukvm secret</name>
</usage>
</secret>
$ virsh secret-define --file secret.xml
Secret 83a0e970-a18b-5490-6fce-642f9052f832 created
$ virsh secret-set-value --secret 83a0e970-a18b-5490-6fce-642f9052f832
--base64 [key for client.qemukvm]
Then use xml with an auth element referencing that secret:
<disk type='network'>
<driver name="qemu" type="raw"/>
<source protocol='rbd' name='rbd/vmxxxxxxxxx'>
<host name='10.0.0.13' port='6789'/>
<host name='10.0.0.10' port='6789'/>
<host name='10.0.0.17' port='6789'/>
</source>
<target dev="vda" bus="virtio"/>
<auth username='qemukvm'>
<secret type='ceph'
uuid='83a0e970-a18b-5490-6fce-642f9052f832'/>
</auth>
</disk>
This secret key handling for ceph was added in libvirt 0.9.7.
