would this be more appropriate:

This move makes it necessary, that the initvm domain name is configured
to a different name, when more than one initvm shall be running on a
single host.

Due to soap tcp port conflicts, we need special configuration of SOAP
Ports already, so this just requires one more thing that needs to be
configured, when more than one initvm shall run on a single host.

---------------------------------------------------------------------
it might also be an option to derive the libvirt domain name from the
soap port. This would reduce config options, but is also not very
intuitive. I would prefer "initvm-torbenh" and "initvm-jogness" showing up
in "virsh list" over "initvm-5678" and friends.
