It is not kernel bug. And it is not a bug at all. It is issue due to the one
vzctl and multiple kernels with and without this module. And I don't want to
add module dependencies in order to get xt_tcpudp loaded with x_tables.
When we'll switch stable branch to >=2.6.16 or add vzctl devel branch, then we
fix it as we done for all other modules. Right now, it is unnecessary work.
Workaround is simple, but if you prepare patches for vzctl AND kernel with
compatibility issues in mind - welcome!
