I have a problem where xen hvm guests using ovmf (efi) as "bios" will not read efi variables stored in <efi-drive>/NvVars. I believe that may be a known bug in old versions of tianocore.
Building xen-tools-4.8.1 now, and I notice that the ebuild still has OVMF_PV=20151110 . Tried building a newer one myself for 4.8.0 by pulling the sources that are referred to in the upstream makefile. However, I can't seem to get it to boot :-/, never mind getting the ebuild to make it. Is there any hope that the ebuild might be updated with newer ovmf source ?
