on containers inside 2.6.32-042stab055.10 kernel most of the time %id is 0%, it dosn't make a difrence that load is 0
outside %id %us and %sy values look normal
it seems that machines are getting there share of cpu (openssl speed runs as expected)

even if container is doing absolutely nothing top shows 90% + user utilization, this doesn't seem right
on rhel5 based kernels total cpu utilization numbers reflected the sum of cpu utilization and %id reflected free cpu
is this reflecting some change in cpu usage reporting inside the containers or is it a bug?
vps config follows
CPULIMIT="100"
PHYSPAGES="0:321536"
NUMIPTENT="200"
CPUUNITS="29153"
NOATIME="yes"
CPUS="4"
SWAPPAGES="0"
thanks in advance for any answers
