Hi Clark,

Patch looks fine, but can you include a test case with it? Something like
tests/qemuxml2argvdata/qemuxml2argv-arm-vexpressa9-virtio.xml and the
associated *.args file, but using the 'virt' machine type. See the HACKING
file for tips on working with the test suite.

Then CC me on the next patch and I'll review and apply.

Thanks,
Cole
