Launching a vexpress-a15 Fedora in qemu

This is based on https://fedoraproject.org/wiki/Architectures/ARM/F21/Installation#For_Versatile_Express_Emulation_with_QEMU, but simplified to a single script:

qcow2=yes # leave empty for raw
image=Fedora-Minimal-armhfp-21-5-sda
file=$image.raw
curl -L http://download.fedoraproject.org/pub/fedora/linux/releases/21/Images/armhfp/$image.raw.xz|xzcat > $file
truncate -s10G $file
echo ",+," | sfdisk -uS -L -N3 $file

if [ -n "$qcow2" ]; then
  qemu-img convert -O qcow2 -o lazy_refcounts=on,compat=1.1,preallocation=metadata $image.{raw,qcow2}
  rm $file
  file=$image.qcow2
fi

wget https://dl.fedoraproject.org/pub/fedora/linux/releases/21/Server/armhfp/os/images/pxeboot/{vmlinuz,initrd.img,dtb/vexpress-v2p-ca15-tc1.dtb}

qemu-system-arm -machine vexpress-a15 -m 1024 -nographic -net nic -net user \
      -append "console=ttyAMA0,115200n8 rw root=/dev/mmcblk0p3 rootwait physmap.enabled=0" \
      -kernel vmlinuz -initrd initrd.img -sd $file -dtb vexpress-v2p-ca15-tc1.dtb

To add the machine to virt-manager

virt-install \
--connect qemu:///system \
--name fedora-a15 \
--ram 2048         \
--arch armv7l      \
--machine vexpress-a15 \
--os-variant fedora21 \
--import \
--disk $file \
--boot kernel=vmlinuz,initrd=initrd.img,kernel_args="console=ttyAMA0,115200n8 rw root=/dev/vda3 rootwait physmap.enabled=0",dtb=vexpress-v2p-ca15-tc1.dtb
--os-variant fedora21  \
--graphics none

Post-installation
