Install Windows Server 2012 R2 virtual machine on Acropolis Hypervisor

This post will guide you through a Windows Server 2012 R2 installation in a Acropolis Hypervisor (AHV) virtual machine (VM).

There are quite a few blog posts released already that covers VM migrations from different platforms to AHV and some that includes new VM installations as well. The main difference with this blog post is the following:

  • It includes the newly released Nutanix ISO based VirtIO driver that can be downloaded form the Nutanix Portal here. The VirtIO driver is required to make it possible to install a Windows operating system based VM using a SCSI disk.
  • PRISM UI based Image Configuration, formerly known as Image Service, usage to manage the VirtIO driver and the Windows Server installation media.

Follow the below steps to install a new Windows Server 2012 VM on AHV.

VirtIO Driver Management

  1. Log in and download the VirtIO driver from the Nutanix Portal. Select Tools & Firmware from the Downloads drop down box. The download the “Nutanix VirtIO 1.0.1 for Windows (iso)”

    3. Disks
      You need a minimum of one SCSI disks and 2 CDROM units:Screen Shot 2015-10-30 at 13.05.22

      1. First CDROM is already present so update that one and point to the Windows Server installation media.

  3.  The installation will start and depending on your media type you might have to specify license and accept the license agreement. When the installation process reaches “Which type of installation do you want” you select “Custom:Install Windows Only (advanced)”Screen Shot 2015-10-30 at 13.23.25
  4. No disk will be present at the “Where do you want to install Windows?” screen so you select “Load driver”

  5. Select Nutanix VirtIO 1.0.1 CDROM Drive and the appropriate Windows Server version. In my case Windows Server 2012 R2

  6. Install both the network and scsi drivers netkvm.inf and vioscsi.inf. Net driver will make sure you got a network card when the installation is finished and the scsi driver will make sure the installation finds the SCSI disk.

  7. When driver installation is finished you’ll see the SCSI disk and you can install Windows Server 2012 R2 according to your standards.

When the installation is finished you should unmount the Windows Server installation media CDROM and remove the VirtIO CDROM.

    Something strange happen! All works but my screen resolution stuck on 1024×768 and i can not change that. I recall doing this with later version and don’t recall having this problem. Any ideias?

    My VM has completely installed. However, it has no NIC applied to it in Windows Server 2012 R2. The is the default NIC attached to the VM in the config.

  6. magander3

    I assume you did add a NIC when creating the VM and you also installed the VirtIO drivers from Nutanix Portal, right?


  7. Oral

    Yes I did.
