Search the mailing lists for cpucap. I had reposted a patch that someone
else had done that would apply to 2.6.8 I believe that actually limits the
% of CPU that a process can use and not just the time it can be running.
Buggy, no guarentees, not supported and I can't even really remember how
it worked, but you might have some luck with it.

The place where you made your stand never mattered. Only that you were there..
And still on your feet.

I want to limit CPU time for a guest instance. What is the best method ?
ulimit would limit total CPU time if thats what you are after.
I run a programme in the background which monitors all the instances
and renices them dynamically. Heavy users get niced heavily. It uses a
simple ruleset so that heavy users who are reniced can be reniced back
to normal again if their usage returns to normal. This works well in
my network (50+ instances over 4 machines). The code is integrated
into my site, so I cannot send you the code, but it was quite easy to
write. This gives "fair usage" to the instances, without an arbitrary
CPU time limit.
