Hello World sample under Windows 11 gives NoHypervisorFound error, no solution provided in the Readme

[enkomio]

What happened?

Hi,
I followed the instructions to build and run the Hello World sample, but when I run the command cargo run --example hello-world I receive the following error:

c:\workspace\hyperlight>cargo run --example hello-world
    Finished `dev` profile [unoptimized + debuginfo] target(s) in 15.09s
     Running `target\debug\examples\hello-world.exe`
Error: Error("No Hypervisor was found for Sandbox, Hypervisor Handler Message Receive Timedout")
error: process didn't exit successfully: `target\debug\examples\hello-world.exe` (exit code: 1)

The readme suggests that this may be a permissions issue, but no suggestion is given for Windows OS. I'm running the code from a Remote Desktop session.

What did you expect to happen?

the string Hello, World! I am executing inside of a VM :) to printed to screen

Steps to reproduce the behavior

all steps in the README end without error, except the last one: cargo run --example hello-world

Thanks for the detailed report. We can definitely improve our documentation here. May I ask if you have enabled hyperv feature on windows? On my windows 11 machine, I have the following 3 windows features enabled (Find this menu by pressing Windows key and then searching for "Turn windows features on or off"

Hi @ludfjig,
I checked and I had the Hyper-V folder flagged, but by expanding the folder, as you did, I had the Hyper-V Platform disabled. I enabled Hyper-V in the firmware, enabled the hyperv feature and now the sample is working!
Thanks!

I'll close this as it seems to be addressed :)
