yes, OpenVZ calculates idle statistics for VE.
it is calculated as follows:
cpu user/system time are incremented as usual on timer tick,
idle time is incremented on per-VE per-VCPU runqueue when there is no tasks
in VE runqueue.
i.e. VE idle time is the time when there were no VE tasks on the runqueue.
