This does not work with the loopback block devices. It seems that it will work with the blktap approach:

This doesn't seem to work with blktap and 2.6.18-92.1.10.el5xen. Also, the combined I/O throughput of two VMs seems to be 2/3 the throughput of 1 on the tycoon-55 and -70 machines. Shelve this until Xen catches up.
