My VM guy gave me 128,000 1K blocks of VDSK swap. I feel this is excessive, especial when you take it out to 7 VM guests. I understand that VM only uses as much of the allocation as is needed but I was wondering what most people are defining this as?
As always, "it depends". How big are your guests? For starters, that's probably 128,000 512-blocks, or 64M. I generally try to have swap the same size as "physical" memory (that is, that'd be about right for a 64M virtual machine), but it really depends on how much your memory consumption fluctuates. If it seems like too much, though, use just a little swap (10M or so) on VDISK, and then put a second, lower-priority swapping device on real DASD.
