Re: [Xen-users] guest domain not booting
Hi Marco,
I'm using a similar setup on Debian with dom0 using sid
and multiple domUs using sarge. (Can't remember why now;))
All domains use kernel 2.6.11.12 (xen testing),
but each compiled with different options.
[end long story]
I haven't really got any answers for you I'm afraid
so hopefully my questions below won't send you
off on a wild good chase!

I assume you just copied your config to xen/linux-2.6.11.10-xen0
and did a 'make dist' or 'make kernel-2.6' ?
If you did it manually make sure to do a
make ARCH=xen oldconfig (or menuconfig....etc).
Did you use a Debianised kernel source for your Debianised config?
(just apt-get a kernel-source and copy it into your xen source root)

Are you sure you need an initrd?

Is this much memory free?
(ie. your system has > 384MB ram?)

Might as well leave it blank then?

If you don't like typing that much:
xm create dom01

Do your syslogs tell you anything?
Perhaps you could do multiple ssh logins to your dom0
from another machine and watch a few logs simultaneously?

Hope that something above helps,
