I love Hyper-V because of its deep integration with the hardware, OS, and
especially powershell. I test my code in Hyper-V because I've found it to
be much faster, safer, and more convenient than testing on a real
machine. Some of my products have user interfaces and I would like to test
my user interfaces in Hyper-V as well.
This is my process:
1. write code
2. run script that
a. compiles binaries
b. turns off my UEFI VM
b. copies the binaries to my UEFI VM's VHDX
c. turns on my UEFI VM
3. play around and make sure my code does what I except
This works great for keyboard input, graphics output, and networking stuff.
The only thing I'm missing to fill all my needs is pointer input.
Can you give me a starting point on how to make a synthetic mouse driver
for Hyper-V, or is that something only Microsoft could do? The device path
for the keyboard Acpi(...)/VenHw(...) makes me think there is no I/O
protocol exposed that I can build on top of.
