Just to confirm for others, the only changes I made to @cdf's default config.plist was adding the new kext, I did not changed the VMM Flag or AppleBootPolicy. RequestBootVarRouting is set to True in @cdf's suggested settings.
I'm attaching my config.plist generated with Plistlib Generator, which emulates OP configuration.
Just compared your config file with the one I have that was generated with OCLP. I'm using beyond compare to compare the files.
You are missing half the stuff I have.
Im including my config if you would like to compare it.
