Automatic Virtual Machine Activation


  • The Hyper-V host is a Windows Server 2012 R2 Datacenter Edition.
  • The VMs are running Windows Server 2012 R2, thus only the below three editions can get activated by AVMA
    • Windows Server 2012 R2 Standard
    • Windows Server 2012 R2 Datacenter
    • Windows Server 2012 R2 Essentials
  • The Hyper-V host is activated. (It can be activated using any of your regular activation mechanisms like MAK, OEM or KMS.)
  • The Guest VMs have AVMA client key installed on it
slmgr /ipk <AVMA_key>

Nesting virtualisation providers

Hypervisor: Vmware Tools / Vmplayer on Windows

Nested provider: Oracle Virtualbox on Ubuntu

Virtual box will throw following error if you do not enable in VMWare Virtual Machine Settings > Processor > Virtualize Intel VT-x/EPT or AMD-V/RVI

Failed to open a session for the virtual machine vagranttest_1371583212.
VT-x is not available. (VERR_VMX_NO_VMX).
Result Code: NS_ERROR_FAILURE (0x80004005)
Component: Console
Interface: IConsole {db7ab4ca-2a3f-4183-9243-c1208da92392}

Hypervisor: Virtualbox

Oracle Virtualbox can nest only 32bit systems, therefore you cannot run Hyper-V hypervisor on it as it would require 64-bit Windows OS. Often this is signalled by following error message "VM-server-#### failed to start. Failed to start the virtual machine 'VM-server-####' because one of Hyper-V components is not running."
