What sort of pre-created tap interface?

A Xen virtual NIC is created by qemu which is only started when the
domain is launched. As far as I know there is no way to "precreate" them
since they have to be created by the process which is driving them.
Please can you explain precisely what you are doing?

You should be able to control this by editing the vif-* scripts to suit
your local environment.
