In my environment the new volume is not listed by virsh
vol-list, even though /dev/disk/by-path shows the iscsi
block devices:

# virsh vol-list --pool iscsi.dpcl064
Name                 Path
-----------------------------------------

# ls -al /dev/disk/by-path/
total 0

The virt-manager GUI knows about the defined iscsi volume,
so I would guess this is just a minor bug in virsh.
