ionescu007 / SimpleVisor

SimpleVisor is a simple, portable, Intel VT-x hypervisor with two specific goals: using the least amount of assembly code (10 lines), and having the smallest amount of VMX-related code to support dynamic hyperjacking and unhyperjacking (that is, virtualizing the host state from within the host). It works on Windows and UEFI.

I'm running win7 pro x64 inside vmware. Test signing is on.

C:\>sc start sv
[SC] StartService FAILED 1275:

What's interesting is that MemoryMon works fine:

C:\>sc start mm

SERVICE_NAME: mm
        TYPE               : 1  KERNEL_DRIVER
        STATE              : 4  RUNNING

        SERVICE_EXIT_CODE  : 0  (0x0)
        CHECKPOINT         : 0x0
        WAIT_HINT          : 0x0
        PID                : 0
        FLAGS              :

Any idea what's the problem?

SimpleVisor does not support Windows 7 as readme states.

It might not be too hard to run it on Windows 7 though. Try setting "Windows 7" on project properties > Driver Settings > General > Target OS Version. It is not going to compile as-is but minor API replacement might suffice to make it work.

It doesn't compile for win7. MmAllocateContiguousNodeMemory is not available. I changed the Target OS from Windows 10 to Windows 7 in my personal project and it worked. Thanks :+1:
