    I am configuring a new PC used for multiple Virtual PC 2007 hosts. I have
    requirement to run XP x32.

    Will VPC 2007 fully use 4GB of RAM on XP x32? Is it worth it over 2 GB?

    It's my understanding that XP cannot address physical memory over 3GB, so I
    don't see how running it as a guest OS would change this.

    Perhaps others have had a different experience?

    My host host will have 4 GB, each guest VM will be allocated 512MB.

    Sorry, addressing memory is the wrong word to use here, as 32-bit memory
    addressing in XP would certainly allow up to 4GB RAM usage. That is of
    course in theory(2^32), in practice XP does reserve approxmately the
    remaining 1GB on a 4GB system.

    A typo? Should be multiple VPC2007 guests, right?
    You could install on XP-Pro X64 instead, then the memory issue is
    VPC2007 is available in both 32 and 64 bit versions so that would not
    make a difference.

    The guests of course will all be limited to 32 bit since VPC2007 does
    not allow 64bit guests.

    Right, x64 Host would solve this delema but it is not an option due to other

    Would an addition hard drive get me above the 3 machine limit? The processor
    will be a new core 2 duo, so that should not be an issue. Is RAM the
    limiting factor or harddrive concurrent access issues?
