that's the source of one of the missing features. Fixing it should be a
case of adding the option to libxl_domain_build_info in the IDL,
reacting to it in libxl__build_device_model_args_old and
libxl__build_device_model_args_new and parsing the config file option
into it in parse_config_data().

This is expected, with xl the script for tap devices is run via the
hotplug mechanism (i.e. the same as vif) whereas xend apparently runs it
via qemu. Either _should_ work.

That's ok, they are effectively arbitrary and just serve to bind the
"-net nic,..." and "-net tap,..." options to one another (IOW the vlan
ID needs to be consistent across those two options but is otherwise
unimportant).
