poor performance running Longhorn Beta 1 on VPC

    My machine specs are
    CPU : 3.0 GHz
    RAM : 760 Mb
    HDD : 60 Gb SATA
    20 Gb ATA IDE

    my primary drive is the SATA drive which has windows XP and Fedora Core 3
    Longhorn refuses to install because it detects "legacy fault tolerant
    disks" (which i found out after googling for days to be caused by the
    Linux partition, even if i want to install on a SEPARATE HDD altogether!,
    i.e. the ATA IDE)
    So i got VPC 2004 running and was finally able to install Longhorn Beta 1.

    The problem i'm facing is extremely low performance on the virtual machine.
    Are there any tips to get it to work better?
    Would a physical linked Virtual drive make enough difference to render a
    reinstall of longhorn feasible?
    btw, i had to leave the installation runnin overnight .. and when i came
    to work the next day, vista was still applying settings :|

    any comments/suggestions will be highly appreciated

  2. Vista does take a long time to install. Try downloading and installing the
    trial version of Virtual Server 2005 R2. That will give you a virtual
    machine additions .iso for R2 which you can then use for installing
    vmadditions for Vista in VPC. These additions are much more recent than the
    VPC additions you are now using.

    This will improve performance of Vista nicely. Be patient while the
    additions install. After the reboot you will find things speed up a lot.
    If I recall correctly, Vista does not support the SB16 soundcard emulation,
    so don't plan on sound.

    After the installation, save a copy of the R2 additions ,iso for future use
    and uninstall the VSR2 trial (or check it out for awhile, of course).

    Vista does not support the ISA bus. That is why the ISA SB16 sound card
    in the VPC guest machine won't work under Vista.

    I'm getting a "Windows Activation" prompt.
    And the Product key i had used earlier (from the msdn subscription site)
    no longer seems to be valid.
    Is this because of the Virtual Server 2005 VS Additions?
    do they require a seperate activation key??

  5. The product key is one thing and activation is another. Activation does not
    have its own activation key. When does Windows say the product key is not
    valid? Do you have internet connection at the time you try to activate?

    Activation does seem a bit dodgy in build 5270 from a virtual machine. I
    have received funny messages from it with both vista and server. Just make
    sure that you have a live Internet connection and try again. They have all
    succeeded finally (vista and both server core and server EE).

    You'll encounter the "invalid product key" problem if you're using a dynamic
    disk. You need to use fixed size disk and the minimum size if 8 or 9 GB
    (don't remember which it was).

    A dynamic disk is OK as long as you partition it. You get the "invalid
    product key" message on a raw disk.

    Apparently you can get that message on a partitioned and formatted disk as
    well, I'm trying to find out why.

    You also get the invalid key message during setup if you don't have enough
    RAM allocated to the VM... (it doesn't work with 256M, but it does with

    Interesting. Seems like there is a major problem with the error
    reporting. No matter what the problem, you get the same message!
