[Xen-devel] Problem on FC3

I''m getting a VFS kernel panic when trying to booting to FC3 from Xen.
Its the one that says I must supply a valid "root=" option.  (sorry I
don''t have it verbatim.)

I''m using the xen-2.0 binary installer, kernel 2.6.9.  I am using
ext3fs, but I am fairly certain that I have compiled support into the
kernel. (I''ve tired compile xen from the 2.0 and nighltly source too
:-).

I''ve tired Keir''s suggestions but to no avail... I''m
fairly new to
linux, but not to unix.  I''m just don''t know what to try next.

Suggestions?

Here''s my setup:

Device Boot
/dev/hdc1
/dev/hdc2            FreeBSD
/dev/hdc3            FC3 Boot (ext3fs)
/dev/hdc4            Extended
/dev/hdc5            FC3 Root (ext3fs)
/dev/hdc6            FC 3 swap

I''ve also got other partitions.

Grub.conf:

default=0
timeout=5
splashimage=(hd1,2)/grub/splash.xpm.gz
hiddenmenu
