[clue] Linux VM image - Should you include a swap parti tion?

[Richard Knechtel]

My general rule of thumb has always been make your swap partition the 
same size as your physical memory. Whether it's physical or virtual. 
I have three different Linux VM's that I had been trying out and that 
is how I do it.
