This is a Fedora 30 Installation on a MacPro5,1 on real hard disks, passed through as reference VMDKs (following the steps from the official guide) and booted fine with all 6.0.x versions. Upon upgrade to 6.1, the EFI of the VM now fails to find bootable item, which is located at \System\Library\CoreServices\boot.efi (as with any normal Fedora EFI installations on Macs, the ESP is in HFS+ and in my specific case it is not the 1st partition of the disk, but previous EFI implementations have always succeeded with this configuration). After being directed to the EFI shell, manually executing the aforementioned boot.efi results in a success boot without any further issues.
