Hi,

I'm trying to add CEPH as Primary Storage, but my libvirt 0.10.2 (CentOS
6.5) does some complaints:
-  internal error missing backend for pool type 8

Is it possible that the libvirt 0.10.2 (shipped with CentOS 6.5) was not
compiled with RBD support ?
Can't find how to check this...


No, it's probably not compiled with RBD storage pool support.

As far as I know CentOS doesn't compile libvirt with that support yet.

I'm able to use qemu-img to create rbd images etc...

Here is cloudstack-agent DEBUG output, all seems fine...

<pool type='rbd'>
<name>1e119e4c-20d1-3fbc-a525-a5771944046d</name>
<uuid>1e119e4c-20d1-3fbc-a525-a5771944046d</uuid>
<source>
<host name='10.44.253.10' port='6789'/>

I recommend creating a Round Robin DNS record which points to all your monitors.

<name>cloudstack</name>
<auth username='cloudstack' type='ceph'>
<secret uuid='1e119e4c-20d1-3fbc-a525-a5771944046d'/>
</auth>
</source>
</pool>
