      Vardhan asked this question in a comment:

      I have tried Windows Server 2012 R2 Preview on VirtualBox but fell over with 0x000000C4 error. Is there any remedy for this?

      I got the same error message. It doesn’t matter if you install from the ISO or the VHD. You always get:

      Your PC needs to restart.
      Please hold down the power button.
      Error code: 0x000000C4
      Parameters:
      0x0000000000000091
      0x000000000000000F
      0xFFFFF801E5962A80
      0x0000000000000000

      The solution to the problem is this command:

      "c:\Program Files\Oracle\VirtualBox\VBoxManage.exe" setextradata [vmname] VBoxInternal/CPUM/CMPXCHG16B 1

      You have to replace vname with the name of your Virtual Machine which you can find in the VirtualBox interface or with this command:

      "c:\Program Files\Oracle\VirtualBox\VBoxManage.exe" list vms

      Don’t forget to set the VM name in quotes if it contains blanks.

      The command enables the CPU instruction CMPXCHG16B. More info here.

      I tried it with the VHD of Windows Server 2012 R2 Preview and it with the ISO.
