[Xen-devel] [PATCH] Guest boot loader support

[Jeremy Katz <katzj@xxxxxxxxxx>]

Attached is an updated version of the patch to add boot loader support
for guest domains.  

Changes from the initial set of patches:
* Per Ian's request, adds an option to specify booting a specific kernel
from the host domain (you can specify it either with the title of the
boot loader config entry or with the grub 0-based index)
* Reduces some of the code duplication for finding out what the virtual
disk to boot off of is
* Improved error handling to use the standard Xen logging and error
facilities

At this point, I think that we handle the use cases where a user just
wants to have everything specified from within the guest domain,
creating a domain with xm create and wanting to be able to interactively
select a kernel and asking for a specific entry from the grub.conf to be
booted when creating a domain.

Future things (which I think are fine to do after the initial pass is
committed) include
* Reworking to use the planned new console infrastructure [1]
* Handling whole disks
* More filesystem support -- the code is generic and has all the hooks,
I just haven't delved deep enough into any of the other fs libraries
* Further improvements for the menu interface

[1] And I foolishly told Ian I'd start a discussion about this last week
and still haven't.  Hopefully tonight.
