Booting Xen directly from GRUB2 command line

[Duncan Guthrie]

Hej folks,
I have installed Grub2 as my Coreboot payload, and now I want to boot Qubes from a USB drive.
Since I haven't made any changes to Grub2's default config, I am trying to boot Qubes from the command line Grub provides.
I do the following:
set root=(usb0)
linux /isolinux/vmlinuz
initrd /isolinux/initrd.img
This is clearly wrong though as it boots without Xen, so when Qubes loads, the little bar only gets to halfway then it crashes into a rescue shell.
What I want to know is how I can boot Qubes from the Grub2 CLI then I can install it. I don't know the right commands.

Something like this (adjust exact filenames and kernel parameters):

multiboot /isolinux/xen.gz (xen options here)
module /isolinux/vmlinuz (kernel options here)
module /isolinux/initrd.img

Just as a heads up you can load a grub config file with "configfile
(DRIVENAME,DRIVEPART)/blahblah/grub.cfg"

Great for testing pre-baking it in.
