Update: Once booted from GRUB -- on top of OVMF / ArmVirtQemu respectively --, both x86_64 and aarch64 Fedora *24* guests work well with virtio-gpu-pci, as far as the character console (tty1, "virtiodrmfb") is concerned. However, for getting an X.org graphical environment (such as Xfce) to work with virtio-gpu-pci, more gymnastics are needed in the guest, on both guest arches. This is because X.org considers "virtio-gpu-pci" a secondary graphics card, and it won't use it even in a single-head setup *unless* the BusID option is specified in the X.org config file, in the Device section. Refer to <http://linux.die.net/man/5/xorg.conf>: BusID bus-id [...] when using a secondary graphics card in a single-head configuration, this entry is mandatory After I placed Section "Screen" Identifier "Default Screen" Device "Default Device" Monitor "Default Monitor" EndSection Section "Device" Identifier "Default Device" Driver "modesetting" BusID "PCI:0:1:0" EndSection Section "Monitor" Identifier "Default Monitor" Option "PreferredMode" "1024x768" EndSection in /etc/X11/xorg.conf.d/01-resolution.conf Xfce too is working fine for me. (Note that BusID must match the PCI $BUS/$DEV/$FUN that QEMU assigns to virtio-gpu-pci, either automatically, or in response to the user's "-device virtio-gpu-pci,addr=$DEV" property.) I guess if someone is into xserver development, this could be made a bit more convenient, because for aarch64/KVM guests at least, virtio-gpu-pci should be considered a primary (not secondary) graphics card.
