of course... but as module, so you need the initrd or your system will not be
able to mount the root filesystem:
~$ cat /boot/config-2.6.12.6-xen |grep XFS
# XFS support
CONFIG_XFS_FS=m
CONFIG_XFS_EXPORT=y
CONFIG_XFS_RT=y
CONFIG_XFS_QUOTA=y
CONFIG_XFS_SECURITY=y
CONFIG_XFS_POSIX_ACL=y
CONFIG_VXFS_FS=m

I never used this libc6 version mentioned in the wiki, so I don't know if is
really working and compatible to xen3 and/or my packages...
I will test them tomorrow, I didn't saw that on the xen wiki till now, must be
new :)
but if you want to be sure, reinstall the orig. libc6, mv /lib/tls
to /lib/tls.disabled and reboot your machine with the xen hypervisor&kernel.
If it crashes again at the same moment, then it is probably not a problem
related to that libc6 package. But I guess the libc6 isn't problem anyway,
because your crash seems to happen before the rootfs is even mounted.

put the following line in your /etc/apt/sources.list:
deb-src http://packages.debianbase.de/sources/xen3 ./
then "apt-get update; apt-get source linux-xen0-2.6" and change to
"linux-xen0-2.6" then.
now edit "debian/rules" and see if you want to change something, maybe the
MAINTAINER or PAE option.
then run "debian/rules build"... this will not build the kernel, but will
download & patch the kernel source as well as building the default config.
if you want to change the kernel config, change dir to "linux-2.6.12" and
run: "make ARCH=xen menuconfig", change what you want to change and then
"cd .." again.
now it's time to compile the kernel and package it... run "debian/rules
install" for that.
your done... for now my source package for the kernel is more or less a hack,
but working. I will make it more eleganter if I have to for it.
compiling xen is even easier (but needs more installed packages, because of
dependencies).... compiling is easy as:
"apt-get source xen"
"cd xen-3.0.0"
"dpkg-buildpackage -b"
done.
