    Howdy. I've just built my own server (Ubuntu host, running three VMs - one for AD, one for SQL, and the other for sharepoint).

    The main box has 12GB of RAM, of which 3GB goes to each 64-bit VM and the host (Ubuntu, 64-bit) gets 3GB as well.

    Could I slink by with 2GB for each VM and host machine and use the new RAM (DDR3-1333, 4gb modules) in my 2009 Mac Pro instead? I do mostly photo editing, but have gotten close to the 8GB max (I do run a XP VM on it for occasional use...) But don't want any server VM to run slowly due to lack of RAM as well (I recall 512MB being minimal, and with MS it's ideal to multiply their claimed minimum by a factor of at least 4, meaning 2GB absolute minimum in real life, but the three VMs will be communicating with each other frequently while I study for some meaningless MCSEs and all...)

    I do a 4GB per VM rule personally. 2 Goes to the VM the other 2 are for virtual swaps. Seems to work pretty well.
