Resending this patch as the one I sent earlier won't apply given the changes we just made to "[PATCH 2/5] Xl interface change plus changes to code it impacts". Description - Special case how we validate vhd image files. Without this patch when tap:aio:vhd prefixed image files are specified in the config file, disk validation and thus vm creation will fail.
