[OSGeoLive] Hyper-V VMs

Thanks for getting back to me. I've been trying out the conversion process using MS tools to avoid reliance on software, that whilst currently free, may not be in the future (the https://www.starwindsoftware.com/converter). Full steps are at the end of the email.
I'm fine with disabling Hyper-V for upcoming workshops - but it may make things a little easier for users in Windows environments to work directly with Hyper-V in the future.
The resultant .vhdx file is 10.3 GB. Using 7-zip this produces a 3.2 GB file. This is essentially the same as the VirtualBox HD file, but in Hyper-V format. It can then be used directly in Hyper-V on Windows 10 Professional (and presumably other versions). I'd be happy to create the vhdx file for Sourceforge and a Hyper-V installation page for the docs if people think this is worthwhile addition to the OSGeoLive project (and should be able to do the same for the v12 planned in the summer).
One drawback with Hyper-V / Lubuntu is there is no equivalent to the "Guest Additions" of Virtual Box. The shared clipboard and automatic full screen don't seem to be available. It looks like this may be on the way later this year - https://blogs.technet.microsoft.com/virtualization/2018/02/28/sneak-peek-taking-a-spin-with-enhanced-linux-vms/
Conversion steps for OSGeoLive 11.0 vmdk for reference are as follows:
- Download the Microsoft Virtual Machine Converter 3.0 from https://www.microsoft.com/en-us/download/details.aspx?id=42497 and install
- Download the "DS File Ops Kit" from http://members.ozemail.com.au/~nulifetv/freezip/freeware/dsfok.zip and unzip
- Open PowerShell (with admin rights)
- Run the following command to get the disk descriptor from the OSGeoLive vmdk:
D:\tools\dsfo.exe .\osgeo-live-11.0-vm.vmdk 512 1024 descriptor1.txt
- This saves the disk description to the "descriptor1.txt" file. Open this in Notepad / a text editor and comment out the following lines (using hashes). This metadata is VirtualBox specific and is not recognised by the converter.
- Run the following command to insert the disk descriptor back into the .vmdk
D:\tools\dsfi.exe .\osgeo-live-11.0-vm.vmdk 512 1024 descriptor1.txt
Failing to do the above steps will result in the error "ConvertTo-MvmcVirtualHardDisk : The entry 0247ca9d-f9aa-4910-9e8c-1c14d83a7749 is not a supported disk database entry for the descriptor."
- Finally run the conversion process:
Import-Module "C:\Program Files\Microsoft Virtual Machine Converter\MvmcCmdlet.psd1"
ConvertTo-MvmcVirtualHardDisk -SourceLiteralPath .\osgeo-live-11.0-vm.vmdk -VhdFormat Vhdx
Above steps based on https://stackoverflow.com/a/49768353/179520 and http://semantive.com/converting-ova-vm-to-hyper-v-format/
