Do you get a kernel oops? or does the box reboot? What happens if you disable
the openfiler's export of the disk devices but let the domu instance start the
iscsi session?
Thanks,
Matt

Subject: Use of iSCSI in domU on Oracle VM 2.1.5
Hello group,
I am trying to use shared storage exported via iSCSI in a OEL 5.2 32bit
domU. It seems that every time I am trying to login to the target I get a
kernel panic. I am using Oracle VM 2.1.5, xen 3.1.4 apparently.
The last entries in /var/log/messages of my domU are:
Jul 26 11:44:22 crsnode1 kernel: SCSI subsystem initialized
Jul 26 11:44:22 crsnode1 kernel: Loading iSCSI transport class v2.0-724.

Jul 26 11:44:23 crsnode1 kernel: register_blkdev: cannot get major 8 for sd
Jul 26 11:44:57 crsnode1 syslogd 1.4.1: restart.
Straight after the "login" the machine dies.
I googled for the register_blkdev... error which seems to be a common
problem with Xen, somehow the dom0 and domU get confused about device
names... Almost all documentation and newsgroup posts deal with iSCSI and
dom0, but no one seems to use iSCSI inside a domU.
http://www.oracle.com/technology/pub/articles/wartak-rac-vm.html doesn't
report any problems either.
Has anyone seen this? All help greatly appreciated.
Best regards,
Martin
