Hi,

  I tried this today, following here
http://wiki.xenproject.org/wiki/Ceph_and_libvirt_technology_preview .

But, I have encountered a problem when creating the SR.  Here is a short
trace showing my working out:-

[root@localhost ~]# ceph osd lspools -m 10.11.4.52
2013-09-03 14:18:28.449001 7f4b74581760 -1 did not load config file,
using default settings.
0 data,1 metadata,2 rbd,3 libvirt-pool,
[root@localhost ~]# cat > sr.xml
<pool type='rbd'>
  <name>ceph</name>
  <source>
    <name>rbd</name>
    <host name='10.11.4.52' port='6789'/>
  </source>
</pool>
[root@localhost ~]# xe sr-create type=libvirt name-label=ceph
device-config:xml-filename=sr.xml
Error code: libvirt
Error parameters: libvirt: VIR_ERR_65: VIR_FROM_30: Invalid secret:
virSecretFree


Any assistance would be appreciated, thanks.
