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'>

<secret type='ceph' uuid='e80afa94-a64c-486c-9e34-d55e85f26406'/>

</auth>

<source protocol='rbd' name='svl-cc1-cinder-volume-1/volume-0a4cdeab-863d-4394-845f-008b993bc4e9'>

<host name='10.34.114.211' port='6789'/>

<host name='10.34.114.212' port='6789'/>

<host name='10.34.114.213' port='6789'/>

</source>

<target dev='vda' bus='virtio'/>

<serial>0a4cdeab-863d-4394-845f-008b993bc4e9</serial>

<alias name='virtio-disk0'/>

<address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>

</disk>

In this case how can I use libvirt to get the disk/volume size information?

Thanks,

Bruce
