A least, one thing less to worry about. Shall be safe to leave it that way.

Another one less.

I think with this you have eliminated the possibility of something 
interfering with the console. So, the issue should be within the 
installation process.

I'm afraid you will have to use the physical console to finish exploring 
this option then. I'm almost sure it's the network detection fault, not 
the console.

No, forget the CD for now. The proof of concept would be to boot 
installation from PXE and without answerfile. Just omit the 
"answerfile=" parameter on your pxelinux config.

Looks good to me.
