Various hypervisor tests

Building

Be sure to enable crt-static

set RUSTFLAGS=-Ctarget-feature=+crt-static

Typical workflow

Each test breaks with int3 to catch in the debugger. At this point, the snapshot can be taken in VirtualBox. Single stepping after the int3 should find a vmcall, which will cause the VM to break out of the hypervisor.

Each test has a goal which ends with a vmcall, so the hypervisor must also catch the vmcall VmExit and check eax. A success will have 0xdeadbeefcafebabe while a failure will have 0x0

restore_memory

Calls GetCursor() to trigger a syscall and then checks for static buffer for a written value.
