Vztop shows a high iowait CPU % periodically, is it reasonable? [message #28362]

Hi, All
I am running 250 VEs on a Debian host.
The kernel is ovzkernel-2.6.18-enterprise.
There is a Quad core 64-bit CPU in my box.

Periodically the CPU iowait % reaches nearly 100%,
the situation lasts for several seconds and the CPU iowait
turns to 0%.

Actually I don't issue any I/O tasks in VEs and HN.

Is it reasonable, or is there any tool for monitoring the
I/O operations in VE?

Thanks!
