Hello everybody

I have a strange problem when i tried to compile my own XEN Dom0/DomU 
Kernel from source (i used the apt-src kernel sources).
I followed this manual:

I created a new flavour called "xen" (see 
and patched the kernel-source with the xen-patches (2.6.31-11).After 
that, i ran:

debian/rules updateconfigs

and i enabled the new XEN config-attributes only for my flavour

For compilation, i ran

DEB_BUILD_OPTIONS=parallel=2 AUTOBUILD=1 skipmodule=1 skipabi=1 
debian/rules binary-debs

And here is the first of my 2 problems. When i omitted the skipmodule 
flag, i got some warnings about missing modules, what exactly does this 
mean (are the modules in the kernel config but not in the kernel source 

Then i set the flag, and the compilation went through fine (about 20 
minutes) but i got the following error:

WW: Explicitly asked to ignore failures (probably not good)
II: New modules (you've been busy, wipe the poop off your nose)
II: Done
dh_clean -k -plinux-image-2.6.31-19-xen
dh_clean -k -plinux-headers-2.6.31-19-xen
dh_clean -k -plinux-image-debug-2.6.31-19-xen
# The main image
# compress_file logic required because not all architectures
# generate a zImage automatically out of the box
install -m644 -D 
/root/linux-2.6.31/debian/build/build-xen/arch/x86_64/boot/bzImage \

install: cannot stat 
`/root/linux-2.6.31/debian/build/build-xen/arch/x86_64/boot/bzImage': No 
such file or directory
make: *** [install-xen] Error 1

I have some knowledge about debian/ubuntu package building, but as i 
discovered, the kernel rules-file is a bit complicated and i don't know 
where the error could be. What i know is that


doesn't exist

Can you please help me, because i really need this Xen Dom0/U Kernel for 
Ubuntu Karmic (x86_64).
