IN RHEL5, you define a block of memory and OpenVZ takes care of what gets swapped and what does not. There are a lot of tuning options you can apply to determine how things get swapped, but the end result is--in my opinion--not a lot of control over how RAM/SWAP is allocated on a per-VE basis.

On a 16G machine wiht 16G swap, you wind up having to allocated 32G of RAM, and let Openvz manage it.

With the new vswap kernel, you can divvy up ram yourself.
