I checked on that. The same value 402 defined in both header-files.
> You can easily check it the number using strace, like this:
> # strace vzctl set 0 --cpuunits 1000 2>&1 | grep syscall
[root at s10b10-0 ~]# strace vzctl set 0 --cpuunits 1000 2>&1 | grep syscall
no output and without the grep pipe:
[root at s10b10-0 ~]# strace vzctl set 0 --cpuunits 1000
