[vserver] Bug or daydreaming: no sched_hard, but still only 1/4th?

first, I think I'm daydreaming, however I don't understand what I may be
doing wrong.

I'm running four vservers and lately, since I started more development
stuff, noticed they only run 1/4th of the available CPU. The typical
default when SCHED_HARD is enabled.

However I've neither SCHED_HARD enabled, nor defined any sched/* limits.

But I was able to get a 1/1 ratio by *manually* with vsched and now have
to use my custom script to set a vserver to 1/1 after launch.

Ok, if you read the version numbers you'll probably so "it's a bug in
that version and you need to upgrade" because I guess they're clearly
outdated. But could that be true?

I won't upgrade the kernel on the existing system, too high is the risk
to break anything. Once I get my new hardware in the next months, I
swear I will ...
