When we are trying to import NetScaler Gateway 10.5 on Hyper-V on Windows Server 2012 R2, we receive the error below:
Hyper-V did not find virtual machines to import from location ...

Create the VPX instance by using the New > Virtual Machine function and connecting the "Dynamic.vhd" file from the Virtual Hard Disks directory which is present after unzipping the release image.
Note: The newly created VPX instance MUST be configured with a minimum of 2GB memory and with 2 vCPUs. Setting the vCPUs is done by changing the virtual machine settings after the instance is created, but before booting.

Problem Cause

There is a known issue documented in the release notes of NetScaler Gateway 10.5, that NetScaler VPX cannot be directly imported into Hyper-V on Windows Server 2012 R2 using the "Import Virtual Machine" function of Hyper-V Manager. The release notes can be found at the bottom of the NetScaler Gateway download page.
