A few comments ...

We don't need to use two ports if we either use a "STARTTLS"-style 
upgrading of unencrypted to encrypted connections (which is the 
recommended way to do things instead of using two ports), or more simply 
we just ditch unencrypted connections.  They're disabled by default 
anyway and not in any way required unless we want libvirt to build 
without GnuTLS.

The port number (16514) is not allocated by IANA, which is good.

IANA registration is a good thing because it makes it less likely that 
libvirtd will fail to start because some other service is using that port.

No one got my ZX81 joke, obviously ...

Rich.
