[Xen-users] iSCSI in guest domains

["Mike Leatherman" <michael.leatherman@xxxxxxxxx>]

Hi,
I'm trying to install Oracle 10g RAC using xen virtual servers and a  
Network Appliance F880 filer as the shared storage. I'm using Xen 3.0.2,  
kernel version 2.6.16u, and my VBD is created from a Redhat 4u3  
distribution.  I would like to use raw devices (disk LUNs on the NetApp  
filer) in conjunction with Oracle ASM to store the oracle database files.
This configuration works well on standard linux servers, but I'm unable to  
get it working on Xen because I can't get the iSCSI initiator to work in  
the guest domains.
I attempted to compile the core-iscsi initiator against the 2.6.16U  
kernel, and it seems to compile ok, but I get "unknown symbol in module"  
error when I attempt to load via insmod in the guest domain. I tried  
open-scsi as well, but also receive errors.
So my question is -

can you launch the iscsi-initiator and deamons within the guest domain to  
establish iscsi connetivity to the iSCSI target (netapp filer), or does  
iscsi have to be started on the xen host (dom0).  If iSCSI can be launched  
from the guest, which initiator should I use with the 2.6.16U kernel, and  
are there any tips on how to compile this initiator to work with Xen ?
Thanks in advance.
