Run linaro aarch64 images with f21 virt-install + libvirt

Linaro generates some minimal openembedded based aarch64 disk images, which are useful for virt testing. There's simple instructions over here for running them with qemu on an x86 host. But with Fedora 21 packages, you can also these images with virt-install + libvirt + qemu.

Grab the disk image, I used this one: https://releases.linaro.org/14.10/openembedded/aarch64/vexpress64-openembedded_minimal-armv8-gcc-4.9_20141023-693.img.gz
Grab the associated boot bits: https://releases.linaro.org/14.10/openembedded/aarch64/Image
Extract the disk image: unar vexpress64-openembedded_minimal-armv8-gcc-4.9_20141023-693.img.gz

Finally, import it with virt-install. The command and output are:

$ sudo virt-install
     --name linaro-aarch64 --ram 1024
     --arch aarch64 --cpu cortex-a57
     --disk vexpress64-openembedded_minimal-armv8-gcc-4.9_20141023-693.img
     --boot machine=virt,kernel=Image,kernel_args="root=/dev/vda2 rw rootwait mem=1024M console=ttyAMA0,38400n8"

(Maybe you're wondering, what about fedora images? They are a bit different, since they expect to run with UEFI. I'll blog about that soon once I finish some testing)
