Hi,
In the output of "virsh dumpxml" command the disk section is as follows:
<disk type='network' device='disk'>
<driver name='qemu' type='raw' cache='writeback'/>
<auth username='svl-cc1-cinder-user'>

</disk>
In this case how can I use libvirt to get the disk/volume size information?
Have you tried 'virsh vol-dumpxml $vol', for an appropriate choice of
$vol? It may require creating an rbd storage pool first.
There's also 'virsh domblkinfo $dom vda', for obtaining information
about the vda disk associated with $dom.
