If you are running VM's you can just copy a working image instead of 
repeating the installs - and if you have fairly identical hardware you 
can do the same with disk images on physical machines.  It's more a 
question of whether that's enough RAM to do anything useful once you are 
running.  In particular it doesn't seem like a great idea to run VM's at 
all if you don't have RAM to spare.
