  • Ideal installation method.

    What is the ideal installation method for Virtual Servers.

    We are trying out VMware Server and are in our initial stages, ... so a basic question.

    We have the base operating OS(win2003srv) in the C Drive, and the Virtual Machines configuration files also in the C Drive.

    The 3 Virtual Machines are loaded in D, E and F drives, 2 windows 2003 servers and a Ubuntu installation.

    Is this the correct method? please advice..

    Virtual applicances are great because you can hit the ground running.

    If you're going to deploy several VMs from the same installation media, It's fastest to convert your CD media into .ISO format and then perform your VM installations from the .ISO file.

    If you're talking about performance impacts, we'd need to know what type of disk subsystem each of the virtual drives tie back to. Typically when someone is testing VMware software, all .VMDK files will map back to the same phsyical drive or RAID array, therefore, there is no performance advantage to creating separate drive letters or putting the OS here, pagefile there, and applications in a 3rd spot.

    From a categorization/housekeeping/personal preference standpoint, creating the logical drives you speak of may make the best sense to you. The two biggest things I'd keep in mind are:

    1) In a phsyical environment, basic storage is cheap and easy to come by. In a virtualized environment, storage is a hot commodity. Just because you'd assign an underutilized 72GB or 146GB hard drive at a phsyical server, you don't necessarily do this in a virtual environment. Unutilized storage is wasteful in the virtual infrastructure and also impacts backup times if you're backing up at the .VMDK level. So what I'm saying here is try to plan up front what reasonable but not wasteful partition sizes should be for the server you are deploying. The good news for some Windows operating systems is that the data drives can be extended using DISKPART.EXE in case you run out of data drive space down the road. The bad news I'll save for point #2.

    2) On Windows VMs, be careful when planning adequate drive space for your boot partition (C drive). The C: drive cannot be extended using DISKPART. If you run out of space on your C: drive, you are essentially stuck without the help of unsupported 3rd party tools like Partition Magic which you may or may not be comfortable with using. Of course this same logic applies to any other OS that does not support volume extensions.

      On this you are right as Microsoft says, but you do not need to this with Partition Magic or other tools.


      In short

      Power off the machine
      Extend the disk size
      Add this Virtual Hard Disk to second vm
      Run diskpart
      Remove the VHD from the second vm
      Power on

      You will have a larger disk size on your system partition.

        The easiest way is to prepare one full installation - your golden image - of each OS.

        Once you have everything configured all you need to do is duplicate that image, rename the virtual machine name and boot it up (if you are talking about and Active Directory integrated machine - then there will be a few more things that need to be done).

        You do not need to have each of your machines on a separate partition - unless these are each different physical hard drives (not partitions)

        If this is the same physical drive - then they can all be in one folder - if that will make your administration better.

        If you are using Raw disk mapping, then they will each need a physical hard driver per virtual disk drive

          Re: Ideal installation method.

          Thank you all for writing....

          As I said we are in testing/learning phase.

          The test system is a IBM X346 Optron 250 80GB SCSI Dual Giga NIC system.

          What we have done is installed Win 2003 Enterprise Server, installed VMware Server, created an iso image of Win 2003 Enterprise Server.

          Created 3 partitions D, E & F with each 10GB and then created the 3 VMs in the 3 partitions. 2 Win 2003 from the iso image and one ubuntu.

          Thanks to all for the ideas and suggestions...

          if there is something more to add please do so...
