Hi Dan,
Maybe I misunderstand what you are trying to do, but I think you are trying to
add your Ceph RBD pool into libvirt as a storage pool?
If so, it's relatively straightforward - here's an example from my setup:
<disk type='network' device='disk'>
<driver name='qemu' type='raw' cache='none'/>
<source protocol='rbd'
name='volumes/volume-f3bcec3d-7daf-4eff-818e-0d8848c120d5'>
<host name='xxx.18.116.67' port='6789'/>
<host name='xxx.18.116.177' port='6789'/>
<host name='xxx.18.116.178' port='6789'/>
</source>
Related libvirt storage pool definition is:
<pool type="rbd">
<name>LibvirtStoragePoolName</name>
<source>
<name>volumes</name>
<host name='xxx.18.116.177' port='6789'/>
<host name='xxx.18.116.178' port='6789'/>
<host name='xxx.18.116.67' port='6789'/>
</source>
</pool>
Hope this helps,
Dan Ryder

Subject: [ceph-users] Ceph storage pool definition with KVM/libvirt
I'm leveraging Ceph in a vm prototyping environment currently and am having
issues abstracting my VM definitions from the storage pool (to use a libvirt
convention).
I'm able to use the rbd support within the disk configuration of individual VMs
but am struggling to find a good reference for abstracting it to a storage
pool. How do I pull the source definition from below to the pool definition?
<disk type='network' device='disk'>
<driver name='qemu' type='raw'/>
<auth username='libvirt'>
<secret type='ceph' uuid='447aba2d-3507-4c1f-90c8-e60ea5ac92fb'/>
</auth>
<source protocol='rbd' name='libvirt-pool/Ubuntu_sample_host_disk'>
<host name='xxx.175.240.174' port='6789'/>
<host name='xxx.175.240.176' port='6789'/>
<host name='xxx.175.240.178' port='6789'/>
</source>
<target dev='vda' bus='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/>
</disk>
Thanks.
Dan
