However, until qemuxml2argvtest can also pull out of genericxml2xmldata,
then you'd have separate xml input and output files - is that what's
desired?

Taking a quick look just now - see the graphics-vnc-socket - do we want
to duplicate having two input/output XML files which invariably will
diverge? Ironically the generic one has a domain type == qemu, an
emulator using qemu, and the socket path using QEMU - so while it's
generic in one sense, it's not in others. Even more ironic is the qemu
specific file uses "<graphics type='vnc' socket='/tmp/foo.socket'>".

Could/should generification of the xml2xml tests be considered a "bite
sized task"?
