Start smaller, say at 192MB or 256MB, and increase it as necessary. Give all your machines plenty of swap on V-DISK. You want to have your machines (preferably) not-quite into swap, or just a little into swap. If you do a "free", the "free" column on the second row (that is, the one that shows how much is free if you count buffers and cache as free) should be small. Even if your Linux machines don't take up all your physical memory even with no overcommittal, as long as you've got plenty of swap defined on VDIS and plenty of memory to back it up, you're better off than you are with too-large Linux machines.
