Bug description:
  qemu-efi_0~20160813.de74668f-1 hangs when booting it in QEMU under
  KVM, though it does seem to work OK when running fully emulated.

  
  $ cp /usr/share/AAVMF/AAVMF_*.fd /tmp
  $ sudo qemu-system-aarch64 -enable-kvm -m 2048 -cpu host -M virt,gic_version=host -nographic -pflash /tmp/AAVMF_CODE.fd -pflash /tmp/AAVMF_VARS.fd

           Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.
           Specify the 'raw' format explicitly to remove the restrictions.
