Xen users - Dec 2011 - XCP Debi an - ISCSI support?

I have Kronos setup fine. I have installed open-iscsi and setup the system
as an initiator. However, I cannot seem to get xapi to allow me to setup the
target as an SR. I was trying to use XenCenter but go nowhere. So I tried
adding it manually and here is what I got:

xe sr-create host-uuid=466aac75-c86a-496f-90e8-2a9925a9e9f7
content-type=user \
> name-label="Shared LVM over iSCSI SR" shared=true \
> device-config:target=192.168.0.2
device-config:targetIQN=iqn.2011-12.store116ib.array1111:tgt
\
> device-config:SCSIid=0 \
> type=lvmoiscsi
There was an SR backend failure.

Does the current xapi have remote SR capability built into it yet?

If not, is it possible to set the SR as LVM and have it set to share=true so
that I can still have the benefits of live migrations etc?

Thanks,

Jonathan

iSCSI SR built in? Yes. Working? Apparently not. We haven''t tested this
SR type yet, and it seems that you''ve found a bug for us. Thanks!

The "No such file" error makes me hopeful that this will be trivia one
to fix, but I''ll have to repro this myself before I know.

Yes, that should be possible. NFS is the SR that we''ve tested the most
so far. Let us know how this works for you.
