Do you have any pointers on the IVARS service?  Documentation, guest
code, host code?

Background:  When moving to a SVSM-based setup where the svsm (with
vtpm emulation) runs in vmpl0 and the edk2 firmware in vmpl1 we might
likewise add a efi variable service to the svsm.

If something usable already exists we don't need to reinvent the wheel.

thanks & take care,
  Gerd
