Hi Dave,
Sorry for the delay. See below

Hi Harri,
I spun up a Debian testing box with the versions of libvirt, iet&
open-iscsi that you're using, and it works fine for me. My pool xml
is:
<pool type="iscsi">
<name>iscsitest</name>
<source>
<host name="localhost"/>
<device path="iqn.2001-04.com.example:foobarbaz"/>
</source>
<target>
<path>/dev/disk/by-path</path>
</target>
</pool>
Gives the 3 configured LUs as volumes:
Name Path
-----------------------------------------
3.0.0.0
/dev/disk/by-path/ip-127.0.0.1:3260-iscsi-iqn.2001-04.com.example:foobarbaz-lun-0
3.0.0.1
/dev/disk/by-path/ip-127.0.0.1:3260-iscsi-iqn.2001-04.com.example:foobarbaz-lun-1
3.0.0.2
/dev/disk/by-path/ip-127.0.0.1:3260-iscsi-iqn.2001-04.com.example:foobarbaz-lun-2
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/

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