If you are are looking to add disk space while the PV guest is in running state , you can use xm block-attach like this:-

xm block-attach <Domain Id> <Backend Device> <Frontend Device> <Mode>

Example :-

xm block-attach my_running_guest_id file://my_path_of file /dev/xvdc w

This backend device file can be created using a dd command.

Running xm block-list $guest1_name | tail -1 | awk '{print $(1)}' should give you the info about the attached device if it is added successfully.

Please refer this link.
