The message is displayed in red, briefly at the bottom of the settings dialog box, when selecting "Settings", then returns to normal. Once into the Network page, you can recreate the exact same condition by blanking out the Mac address. So, I think it is reasonable to presume this is a timing issue between normal error processing and the display process - in other words, the error message displays before the gui is finished reading the xml file(s).
So, this looks like a bug. Especially since the only VM that no longer works (after the upgrade) is the XenServer guest I've created, it's probably safe to say this is pilot error and close this thread.
However, for the record, before I upgraded to 4 I was able to install XenServer under vbox and properly initialize the nic to permit me to communicate with the host. After upgrading to 4.0 the nic does not connect and the network interface simply does not work with XenServer. Which I find strange.
