-Now we should set up OpenVZ environment in obtained tree: kernel, vzctl, vzquota, template. For vzctl and vzquota we can use precompiled packages from http://debian.systs.org. But at the moment we have to create kernel Debian package by self, because we need additional patches in order all to work smoothly (but it will be unnecessary soon, when patches will be included in main OpenVZ patch). This is important to use KNOPPIX default kernel config! The creators of LiveCD take a lot of care about customizing config file in such manner, that CD will suite as many users as possible. We shouldn't throw away such great job. We do `make oldconfig` and press enter all the time. Additionally CONFIG_MATH_EMULATION should be turn off at the moment.
