[Users] Kernel 2.6.20 with openvz-patch on Ubuntu Feisty Fawn (7.04)

[Christian Kaiser2]

I have a problem with compiling a kernel with the openvz-patch. Here are
the steps that I undertook:

1) Download Kernel 2.6.20 from kernel.org
2) Apply openvz patch with "patch -p0 < patch-ovz005.1-combined"
3) Used my original kernel configuration from Ubuntu 7.04
4) make xconfig
5) make-kpkg clean
6) make-kpkg --append-to-version custom --initrd kernel_headers
kernel_image

Here's the error message that I get when running step 6:


...

Does anybody have an idea what's wrong here?



Kernel 2.6.20 is under development. So an error like this can happen. I'm
not sure but I think that checkpointing is broken in 2.6.20 OVZ Kernels. So
try 2.6.18 + OVZ Patches (that should be more stable) or remove
checkpointing support in the 2.6.20 kernel configuration (OpenVZ menu, then
checkpointing) and retry the compilation.
