I've put new 9xeninst binaries on sources which should replace the
spurious "file does not exist" message with a more accurate (but still
not very helpful) "i/o error".  I'm sorry I can't provide a better
diagnostic, but the xen virtual block device just returns BLKIF_RSP_OKAY
or BLKIF_RSP_ERROR.

I haven't been able to test it myself because I don't have a functioning
xen system at present.

Most of the interesting error diagnostics from the xen hypervisor itself
come out only on the serial console.  If you can hook up another machine
to display your xen system's serial output, you might get more info
about why the virtual disk i/o is failing.
