http://debian.systs.org I suppose. The wiki page you referred gives info 
about how to configure this.

These instructions are OpenVZ-specific, i.e. they only recommend 
openvz-specific options in kernel config. Any other kernel config 
options (there are a lot of) are on your own. One simple example of what 
could be done wrong -- if you haven't enabled support for SATA disks, 
and your HDD is SATA you are in trouble.

So, if you are not experienced in kernel recompilation, you'd be better 
of with precompiled kernel.
