When I try to use an iscsi direct pool in a "--disk" clause for
virt-install, I get error "iSCSI: Failed to connect to LUN : Failed to log
in to target. Status: Target not found(515)". I've seen that sort of error
before when the initiator name isn't used. The SAN returns different LUNS
depending on the initiator.
I've run out of ideas on what to try next. Any advice welcome. I've
included what I thought was relevent below.
klint.
The disk parameter to virt-install is (it's part of a script but the
variables are correct when executed)
[code]
--disk
vol=${poolName}/unit:0:0:${vLun1},xpath.set="./source/initiator/iqn/@name='iqn.2024-11.localdomain.agbu.agbuvh1:${vName}'"
\
[/code]
I added the xpath.set as I noticed that the initiator wasn't in the debug
output of the disk definition and it didn't work without it either.
The iscsi direct pool is defined and it appears to work - it's active and
vol-list shows the correct luns.
Using --debug on virt install, I can see the drive is detected early in the
process as it's got the size of the drive.

* What I'm calling a SAN is a seagate exos-x iscsi unit
* virtual host is debian 12
* virsh version 9.0.0
* iscsiadm version 2.1.8
