[Users] Sources of OpenVZ Kernel Debian packages

[Roman Haefeli]

Hi all

I'd like to test patches created by OpenVZ devs and would like to be
able to compile my own OpenVZ kernels for our Debian hostnodes. Where
can I find the source packages to build OpenVZ kernels as .deb packages?
Unlike other OpenVZ Debian packages like 'vzctl' or 'ploop', the kernel
sources cannot be downloaded by:

$ apt-get source linux-image-2.6.32-openvz-${VERSION}

Specifically, I'm interested in the sources of this:
http://download.openvz.org/debian/dists/wheezy/main/binary-amd64/kernel/linux-image-2.6.32-openvz-042stab092.2-amd64_1_amd64.deb

Thanks, 
Roman
