See how to use this: https://github.com/Code-Hex/vz/wiki/How-to-debug-virtualization-framework

This API is necessary to check the kernel actually works fine.

For what it's worth, more details regarding step 7 in https://github.com/Code-Hex/vz/wiki/How-to-debug-virtualization-framework would be useful. Can https://elinux.org/Debugging_The_Linux_Kernel_Using_Gdb be used? Or are there some virtualization framework specific steps to know of? Or is it meant to debug something host side, not something running in the guest?

@cfergeau I added a few details to the wiki page but I don't have knowledge about debugging the kernel.
I confirmed that it worked, but I didn't know how to debug it, so I needed to learn more...

You can edit the wiki page from now!

The added instructions are helpful, I'll give it a try!
