Virtme looks interesting. If it's any use, here is my modest QEMU command line
collection.

$dir/bin/x86_64-linux-gnu/qemu-system-x86_64 \
  -m 1024 \
  -kernel $dir/boot/x86_64-linux-gnu/bzImage-x86_64 \
  -append 'root=/dev/root init=/sbin/x86_64-linux-gnu/init rootfstype=9p
rootflags=trans=virtio,version=9p2000.L ro console=ttyS0' \
  -serial stdio \
  -fsdev local,id=root,path=$dir,security_model=none \
  -device virtio-9p-pci,fsdev=root,mount_tag=/dev/root \
  -monitor none

This is similar to what virtme does, except that virtme will give you
a much more functional system at the cost of a small fraction of a
second of additional boot time.  And virtme sometimes supports modules
:)

Can you give me some hints as to how to configure a kernel for this?
I tried to get anything other than versatilepb working and gave up.

I think you can just use vexpress_defconfig. If you want to from there you can
unselect CONFIG_ARCH_VEXPRESS and set CONFIG_ARCH_VIRT=y, but I don't think
that's strictly necessary.

Ooh, thanks!  I'll add support for this to virtme.

Cheers,
Christopher
