I ran git bisect on OVMF repository [5] to find the commit that broke booting of macOS + Clover combination in QEMU/KVM. It seems that commit 805762252733bb is problematic for some reason. Reverting this commit fixes the macOS booting problem. In summary, I am able to boot macOS 10.12.5 + Clover combination with latest OVMF (commit 1fceaddb12b with 805762252733bb reverted) + updated QEMU (commit aaaec6acad7c with patch from this thread applied). I don't know what commit 805762252733bb does yet but I will look at it again. I am CC'ing Laszlo Ersek, the author of this OVMF commit.
