As I suspected, this disk image is inapproprite for UEFI virtual machines. $ guestfish --ro -a Fedora-x86_64-20-20140407-sda.qcow2 ><fs> launch ><fs> list-filesystems /dev/sda1: ext4 It has no EFI system partition. The image must have been prepared for BIOS machines. (For VMs that implies SeaBIOS, not OVMF.) -o- For cases #1 and #2, I looked into <http://people.freedesktop.org/~kay/installer/installer.sh>. It - formats an EFI system partition as FAT32 alright, - mounts it as "/run/installer-$ROOT/system/boot", - does some other stuff, - and then executes chroot /run/installer-$ROOT/system/ gummiboot install --no-variables I assume something goes wrong in this step (ie. the ESP won't contain any gummiboot binary under EFI/BOOT/BOOTX64.EFI). "install.sh" seems to support formatting regular files -- that should allow you to both upload one for inspection (eg. with guestfish, see above), and also to test it with qemu (without needing a USB stick). Thanks Laszlo
