OVMF is a UEFI-based firmware for KVM.
Install the OVMF-x86_64 packages from this copr. Run guest with the "-bios /usr/share/OVMF/OVMFX64.fd" (or -pflash instead of -bios) option. The TianoCore splashscreen should come up instead of SeaBIOS's.
The package is noarch and can be used on any architecture, albeit possibly without KVM support.
