    Giving Maximum Memory to Virtual Server

    I am buying a Dell R900 Virtualization Server. I placing 96 GB of memory on
    it. I will be running Windows 2003 Enterprise with Virtual Server 2005.
    Windows 2008 is not allowed on our network due to it not being approved (Most
    MS OS's without a first Service pack are not approved)

    Now inside the configuration for Virtual Server 2005 in the memory
    configuration it allows for the following:

    The amount of memory can be from 4 MB through 3712 MB (3503 MB is the
    maximum recommended value).
    Virtual machine memory (in MB): 1028

    Since I will wanting to use more than 3713 MB of memory per virtual machine
    what do I do (or is it only showing this since the Server only has 4 MB of
    Memory)?

    I mean I have 96 GB I want to use at least 1/4 of since I can have 3 host OS
    according to the Windows license.



    Also why is the Virtual machine memory (in MB): 1028 grayed out. Why can't
    I change this?

    Re: Giving Maximum Memory to Virtual Server

    What you are running into is a result of the difference between 32-bit and
    64-bit OSes. A 32-bit system (whether on physical hardware or in a VM) is
    limited to basically 4 GB of RAM. Virtual Server 2005 (any version) cannot
    support 64-bit VMs; therefore, you'll never get around this issue with
    32-bit VMs.

    This is just another big reason to move to Hyper-V and Server 2008 ASAP.
    Incidentally, Windows Server 2008 already includes Service Pack 1 (install
    it and go Start, Run, WINVER (Version 6.0 [Build 6001:Service Pack 1])

    Hope this helps,

    It doesn't matter how much RAM your server has, it will not provide more
    than the listed amount per VM. And only a single CPU core per VM.

    Server 2008 is SP1. And Hyper-V is a FAR better solution than Virtual
    Server.
