The VLM has been tested with Windows Server 2008 R2, Windows Server 2012, Windows Server 2012 R2, Windows 8 and Hyper-V 2016. The Microsoft Hyper-V virtual machine guest environment for the VLM, at minimum, must include:

  • 2 x virtual processors
  • 2 GB RAM
  • 16 GB virtual hard disk capacity
  • At least one Network Interface Card (NIC)

Deploy KEMP Load Master

The downloaded KEMP image has Hyper-V VHD disk and you can use same to create virtual machine or you can convert this to VHDX like below.
