No, I don't believe so. I am running a small but fine build-host with pbuilder 
and some script to automaticly update & build debian source packages for 
multiple releases.

Each release (woody, sarge, etch, sid) has it's own build pbuilder image 
(minimal debian installation), which is automaticly updated once a night. 
Every build process always starts in a fresh and clean build enviorment.

If you want I can also mail you the build log from last night where my 
xen-2.0.7-2 package was compiled on etch (testing).

Yes, the official debian mirrors doesn't provide any kernel-source-2.6.11 for 
sarge, etch or sid anymore. 

I just put an older copy of this kernel in my build-system because the debian 
xen package still needs this image to correctly compile xen (I haven't fixed 
that in the debian package yet). Later in the build process the build script 
downloads the 2.6.11 kernel from ftp.de.kernel.org and uses this kernel to 
build xen. So the debian kernel is irrelevant.

Yes, you can use it if you want.

For testing use this line in your /etc/apt/sources.list:

 deb http://packages.debianbase.de/etch/i386/xen ./

It is a normal xen 2.0.7 with two small patches:
 - a patch for a xm save/restore problem (patch by Ian Pratt (included already 
in xen-testing)
 - a oatch which enables the build of sv (xensv)

There are NO xen kernel images in these packages, so you have to compile a 
kernel for dom0 (any maybe domU's) on yourself.

if you want to compile the package yourself (and want to check if this works 
on your testing host) use this line in your sources.list:

deb-src http://packages.debianbase.de/sources/xen ./
(you must have installed the debian kernel-source and kernel-patch-debian for 
2.6.11 before compiling)

feedback appreciated :)
