I remember I made some tests some months ago with iSCSI in domU.

I tried it with the block-iscsi script of Kurt Garloff, (Novell/SuSe)

You should be able to have in domU config script an entry which
starts with 'iscsi' instead of 'phy';
something like this:
disk = [ 'iscsi: iqn.2001-01.com.example:diskraid-sn-a8111309', hda, w' ].

It could be that this attitude will be slower a bit than the alternative;
which is perform login to iSCSI targets from domU and than mounting
them from domU.
