Windows Server 2008 R2 Hyper-V – 10 things to remember

Posted by Mikael Nystrom on November 10, 2009

 

  1. Storage, store the .VHD file and the settings file at the same location and if possible format the hard drive using 64k blocks instead of using standard, that will increase speed and lower impact on the parent partition

  2. The Time Synchronization service should ONLY be enabled when the child OS does not have any other way of getting the correct time, that means that member servers, domain controllers, workstations in a domain should NOT get the time from the parent partition. Also it is important the the parent partition get’s the correct time, if the parent partition is part of a domain then it should sync from that of course.
  3. When upgrading from Hyper-V RTM to Hyper-V R2 you need to turn of all running machines and you need to remove all snapshots. BEFORE you start them up please modify the following:
    1. Add a SCSI interface and move all disk’s to the SCSI disk instead of having them on the IDE interface, that makes it possible to de-attach them if needed whiteout turning of the machine later on (It has NOTHING to do with performance, just management)
      SCSI Stuff
    2. Check the CPU Setting, there is a new feature that enables you to migrate between machines that NOT have the same CPU, you wnat to have that checked before you want to move it, otherwise you will have to turn it off before moving it, kind of boring
      CPU stuff
  4. Need to sleep, adding the rest later…
