I/O priorities in OpenVZ are proportional share so I don't think you can do what you want. There was a dm-band project released a little while ago that provides hard limits on disk I/O bandwidth for both Xen and OpenVZ.

Perhaps you could petition OpenVZ to include this, although from what I can tell from talking to Kirill they have a full plate for the next few months.
