Yes, will do.

I have / in /dev/sda1 in my host system. So, I tried:

  disk = ['phy:sda1,sda,w']

IIRC, in Hurd with GNU Mach, there is no SCSI support? Anyways, I
proceeded to do:

  sudo xm create -c hurd

=== OUTPUT ===

Using config file "/etc/xen/hurd".
xenconsole: Could not read tty from store: No such file or directory

=== END ===

I got the prompt back. I tried "sudo xm list" and the output was:

=== OUTPUT ===

Name                                        ID   Mem VCPUs      State   Time(s)
Domain-0                                     0   731     2     r-----    467.7
hurd                                         2   256     1     --p---      0.0

=== END ===

But, should we see some console log output or boot messages? After few
seconds, I get " Error: Device 2048 (vbd) could not be connected.
Hotplug scripts not working." message. I now try to do "sudo xm list",
and I get only Domain-0 in the output:

=== OUTPUT ===

Name                                        ID   Mem VCPUs      State   Time(s)

=== END ===

1. Do we need to specify anything to get the console output? On
running "sudo xm create -c hurd", are we expecting some output?
2. If there is no SCSI support in GNU Mach, but, host system uses
sdaX, what parameters do we need to use for 'disk'?

Thanks,

SK
