    I need to virtualise a physical server and have attempted to create a virtual copy using Virtual Server R2.

    I have carried out the following steps;

    1. Created a backup of the System Volume and System State using NTBackup for the physical server
    2. Created a new Virtual Server using the same Operating System (Windows 2003 R2 SP2)
    3. I have then attempted the restore the Backup of the physical server, onto the virtual server.
    4. During the restoration procedure a dialog appears requesting the original SP2 CD to copy certain original files, which cannot be found on the DVD.
    5. After ignoring this and on reboot after the restore is completed, I get the following error;

    “Windows could not start because the following file is missing or corrupt:

    system32ntoskrnl.exe.
    Please reinstall a copy of the above file.

    I have tried running the Repair Console from the installation DVD, but the console does not accept the administrator password.

    Does anyone have any suggestions on a workaround?

    Regards,

    I have to tell you this is a pretty very odd P2V process you got yourself there… Why would you use such a method? I can see only problems with it… When you back up the system, everything is backed up. When you restore it, all the files that fit the virtual machine will be replaced with ones that do not…
    I suggest you use one of the documented P2V processes for Virtual Server 2005.

    Hi Sorinso,

    Thanks for taking the time and effort to answer my question. I’m not an expert on virtualisation, but the method I was following for the P2V, was one outlined in Ben Armstrong’s book on VS2005, (Professional MS Virtual Server) who is an author I respect on this particular subject.

    As you suggest, the method is problematical unless configurations of physical and virtual machines match as closely as possible.

    I did eventually solve the problem by editing the boot.ini file. However, I must say I got excellent results when I eventually decided to use VMWare Workstation, and its virtualisation functionality. Worryingly large vhd files but a perfect copy of the physical server.

    Anyway, thanks for replying, and I’m sorry I didn’t respond sooner.

    Ben Armstrong is indeed a specialist … I was just pointing out the fact that it’s not a process we are encountering these days.
    It might have the only option back then (if you’re talking about this one, it’s three years old), today might be other options (including tools that can do everything with a single click.
    Anyway, I am glad you solved the problem. And thank you for posting back the solution.
