When using vSPC (Virtual Serial Port Concentrator) in vSphere the actual address for it is saved in serialX.vspc in which case the serialX.fileName is most probably something we can't get any useful information from and we also fail during the parsing rendering any dumpxml and similar tries unsuccessful. Instead of parsing the vspc URL with something along the lines of `virURIParse(vspc ? vspc : fileName)`, which could lead to us reporting information that is very prune to misuse (the vSPC seemingly has a protocol on top of the telnet connection; redefining the domain would change the behaviour; the URL might have a fragment we are not saving; etc.) or adding more XML knobs to indicate vSPC usage (which we would not be able to configure; we'd have to properly error out everywhere; etc.) let's just report dummy serial port that leads to nowhere.

I'll try to figure out what's the best way of keeping the serial in a way that it does work seamlessly with the main (only?) consumer - virt-v2v.
