It's redundant, but the <qemu:args> variant is just temporary until the
patch is accepted and we can get libvirt support.  I think the way that
I'll choose to enable on my system until then is via a wrapper script.  For
instance, create a script with something like:

#!/bin/sh
exec /usr/local/bin/qemu-system-x86_64 \
`echo "\$@" | sed 's|hv_time|hv_time,hv_vendor_id=|g'`

Then change the <emulator> tag to point to this script.

Free form string or blank, 12 characters.  As the patch indicates, the
value is only used for reporting and diagnostic purposes.
