Script wasn't able to handle path that Packer used to create VM in the first place:
"==> hyperv-iso: Copying to output dir...
==> hyperv-iso: Error exporting vm: PowerShell error: Move-Item : An object at the specified path C:\Users\HANNU~1.PIK does not exist.
==> hyperv-iso: At C:\Users\hannu.piki\AppData\Local\Temp\ps520830935.ps1:13 char:1
==> hyperv-iso: + Move-Item -Path "$srcPath/$vhdDirName" -Destination $dstPath -Verbose
==> hyperv-iso: + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
==> hyperv-iso: + CategoryInfo : InvalidArgument: (:) [Move-Item], PSArgumentException
==> hyperv-iso: + FullyQualifiedErrorId : Argument,Microsoft.PowerShell.Commands.MoveItemCommand"
Used path was: C:\Users\HANNU~1.PIK\AppData\Local\Temp\packerhv616791918\export253729206\2016min
Real path was: C:\Users\hannu.piki\AppData\Local\Temp\packerhv616791918\export253729206\2016min
Because Packer has already verified that we are running with at least Hyper-V administrator rights this should
be safe. Having the requirement for administrator rights in the script means that you still need to be an
administrator if you want to use packer to build Hyper-V images with a configuration that requires you to
send keystrokes to the MV, say when building a Linux box.
