    This is a follow up to the following thread which I found in the archives:
    http://forum.parallels.com/showthread.php?t=3306&highlight=xen

    I know this seems a little weird, but as discussed in the other thread there's some reasons why I'd like to do this. It would seem that there was some success in the past getting Xen working inside Parallels.

    Here's my config:
    PD build: 4128 (3.0, which is latest as of today)
    Xen: 3.1.0 (which has a 2.6.18-xen kernel, also latest as of right now)
    Dom0: Ubuntu 7.04 (also latest as of today)

    When trying to boot Dom0, it would seem like it's not seeing the hard drive. I'll post the boot log next in separate posts, but basically it gets to where it's trying to load the modules and can't. This looks similar to a problem that was discussed in the reference thread. Of course I might just be doing something dumb in my config, so I need to figure out which it is.

    I've tried with both sda and hda as root param just in case (which also confuses me as parallels presents an IDE drive so why do I see sda getting used when successful in the other thread?).

    Any help would be much appreciated!
    Thanks,
    Rich
