It''s supposed to default to using pygrub if no kernel is specified, is
this still true after your change?

I don''t think it actually worked correctly before with xm.

Using a vm config file with the following entries and the domU kernel as 
the first title in grub.conf

name = "test"
memory = 512
disk = [''file:/temp/fc8-i386.img,sda,w'']
bootloader = "/usr/bin/pygrub"

I tested using ''xm create'' in Xen-API mode by enabling and
disabling the
''bootloader'' line and got this here:

  - without the patch and the bootloader line ''on'' : 
''Internal Error: Had
a bootloader specified, but no disks are bootable''
  - without the patch and the bootloader line ''off'': 
''Internal Error: Had
a bootloader specified, but no disks are bootable''
  - with    the patch and the bootloader line ''on'' :  * boots
domU *
  - with    the patch and the bootloader line ''off'':  * boots
domU *

I think the patch solves the problem with the bootloader.

Is it possible to have pygrub display its GUI while doing ''xm
create''?
How?
