In that case, no swap on the VMs, ever. I agree with the rational mentioned above that RAM is cheap Anyhow it strongly depends on the machine and its use.

For my production machine never hibernates , the swap is zero. If it starts to swap then the performance drops drastically. It is better that the application is killed due to insufficient memory and I am forced to find a solution rather than running at lower speed without noticing. I find that on my personal laptop system, I do not have numerous parallel tasks going on at the same time, chewing up resources and I seldom consume even half of available memory, so under these circumstances, swap is optional unless I care about suspend or hibernation operations.

I usually allow 1 to 2 times system memory to account for suspend or hibernate; otherwise I let virtual memory manage matters, and since neither disk or memory are issues, I do create swap, "just in case". In practice, with moderate utilization and applications regularly changed, I don't usually have a lot of processes chewing up memory. The guidelines are only general and do not necessarily represent all situations, certainly not my typical usage scenarios on home equipment.

These rules of thumb need to differentiate between workstations and servers and backend storage. No one hibernates a server. For my personal desktop or laptop, I allocate enough swap to cover my hibernation needs. I don't want them to every use swap and impact the other servers on the same SAN. I'll first say, laptops are an exception due to the needs of hibernation. In server environments, I run with none or minimal swap.

Since the ESX host box already had a decent sized swap, I found that I could reduce swap or page file for Windows on my guests. My theory here was that only the Host OS knows the real hardware situation. Swap is really a function of hardware - limited RAM to be exact.
