When a guest has an ISCSI volume attached as disk, backend is not returning path correctly, it return a blank field. This patch fixes this problem, returning the path = <iscsi pool> - <volume unit>.

So do you mean if you attached a disk at create time of vm? If I attach iscsi volume to vm as 'block' src_type in runtime and the attached disk in vm xml will be like: <disk type='block' device='disk'> <driver name='qemu' type='raw'/> <source dev='/dev/disk/by-id/scsi-14945540000000000a9317b0c790140de31c9bfc43cd66411'/> <target dev='vdb' bus='virtio'/> <alias name='virtio-disk1'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/> </disk> So the path of iscsi volume is: <source dev='/dev/disk/by-id/scsi-14945540000000000a9317b0c790140de31c9bfc43cd66411'/> which you can read from the volume xml. virsh # vol-list --pool iscsi-1 Name Path ----------------------------------------- unit:0:0:0 /dev/disk/by-id/scsi-14945540000000000a9317b0c790140de31c9bfc43cd66411 I think you can report path using this value.
