Could be a thread I started. I got terrible performance with iSCSI on 
the DomU, but quite acceptable performance after moving the iSCSI 
stuff to Dom0 at the suggestion of people on this list - had to wait 
until I could beg another hand-me-down server to test it on though :-(
That's with Debian Lenny in Dom0 and DomU, iSCSI box is a Dell AX100i.

If you have the patience ! I nearly suggested that earlier in the thread.

Still, our iSCSI box has just taken 8 days to add a drive to an array 
- good job it can do it with the volumes online.
