I had something similar, I think, with a Nexenta DomU doing ZFS storage
for the other Dom0's.  I wound up having to do:

  /usr/sbin/xm sched-credit -d 0 60000

to keep them from deadlocking.

I have iscsid mounting the volumes and then exporting them to Xen like:


'phy:/dev/disk/by-path/ip-192.168.1.3:3260-iscsi-iqn.1986-03.com.sun:02:b1723f77-ac5f-4037-a3c7-9e9458f86679-lun-0,hda,w',

What I need to do still is write a daemon to live on Dom0 that will
listen for the DomU reporting that it's up and services are ready and
then start the dependent DomU's.  Hackish, but now I have to start by
hand or make some WAG's with sleep statements.
