I actually gave up on this one, "make menuconfig" wasn't showing me
the XEN options, and didn't have arch/xen directories, so I assumed
there was something wrong in it. I pulled the tar ball for the xen
web site. It does bring up an interesting point though, the one
from the tar ball is based on 2.6.16-33 rather than -49.
okay... for me oldconfig (and also menuconfig) brings me new xen-options menu.

Yes, I have used that document.

You mean it does not even start booting up, or does it end up panic'ing ?
Are you using an initrd ? What version of mkinitrd do you use (gentoo
stable has tree right now) ?
I am praying all the penguins to run into K panics.... but what I face
is no boot at all, so, no little piece of log.

But... the XEN'ed kernel cannot write to the filesystem until it has
managed to mount it, from what you are saying you don't get to that
point, do you ?
you're right, but I am riding an ext3 fs which support is included
into the kernel itself, so I *should not* face fs problems.... but I
be sure... since no log. What's wrong on that kernel ? no idea. I
retrieved the fs/network/optim/ options (all built into the kernel, no
module to be sure) from the running kernel via make oldconfig ....

Well JFS for sure, since my partition is JFS, but obviously something
else too that I am not aware of :-(
JFS sounds sensible in your case :o). Maybe I am coming up against the
dark side of the dark force you faced before :o(.
Well, it is my first try with xen, and I have no idea about patching
vanilla sources to make them xen compatible -xen-sources are in for
that purpose- but if you tell me it is not a hard pain, I can have a
deeper eye on it.
