[Qemu-devel] Booting a guest with OVMF

[Kashyap Chamarthy <kchamart@redhat.com>]

Heya,

Laszlo pointed out OVMF packages for Fedora from here[1]. I tried a
simple test using this[2] by installing Fedora onto a USB stick.

Once Fedora is installed on the USB stick (/dev/sdb), and I attempt to
boot into the USB device as below, I get the Fedora serial console login
prompt just fine through a QEMU vnc display:

    $ sudo qemu-system-x86_64 -machine accel=kvm -m 256 -bios \
      /usr/share/OVMF/OVMFX64.fd  /dev/sdb)


However, when I try with the below QEMU invocation, I get "Boot Failed.
EFI Floppy":

    $ sudo qemu-system-x86_64 -machine accel=kvm -m 512 -nographic \
      -nodefconfig -nodefaults  -serial stdio \
      -bios /usr/share/OVMF/OVMFX64.fd /dev/sdb
    Boot Failed. EFI Floppy
    Boot Failed. EFI Floppy 1


Next, I tried booting into a Fedora disk image with the below QEMU
invocation, and I get a UEFI interactive shell as below (after "Boot
Failed. EFI Floppy"):

    $ sudo qemu-system-x86_64 -machine accel=kvm -m 512 -nographic \
      -nodefconfig -nodefaults  -serial stdio -bios /usr/share/OVMF/OVMFX64.fd \
      -drive file=/var/lib/libvirt/images/Fedora-x86_64-20-20140407-sda.qcow2,if=ide,format=qcow2,cache=none

Is this expected behavior?
