The Scenario
I have used Microsoft Virtual Machine Converter 3.1 to convert a VMware VM running Windows Server
The Problem
The conversion completes but produces an error right at the end when it tries to install Hyper-V Integration Services on the guest OS:
Could not locate Integration Services installation disk image
The older Wndows Server OS is looking for the C:\windows\system32\vmguest.iso file to mount and install but it is no longer included in Hyper-V 2016 – with 2016 guest VMs get Integration Services updates directly from Windows Update.
The Solution
The solution is to copy the vmguest.iso file from an existing Hyper-V 2012 R2 installation to the 2016 Hyper-V server. Then mount this ISO to the DVD Drive of the guest VM. Then in the OS of the VM run the installer.
