	I don't generally create swap partitions within a VM image, and opt to 
attach a separate volume for swap, or use a swap *file*. The advantage 
for a swap file, is that it can be created automatically via 
kickstart/cloudinit scripts. I really only use swap to prevent oomkiller 
from killing my processes.

	The dd method in the StackExchange looks good if you're preserving your 
VM image.
