Hi Thomas,

Thank you for the help. Great first guess! Adding the MAC address fixed the 

What is your rationale behind upgrading to 2.9.1 or 2.10.0? Do you think it 
will fix the issue and not require the MAC address to be provided? In either 
case I can't update yet as Mr. Weil has not yet compiled win32 binaries for 
those versions.

The new command line looks ok to me at a first glance. Blind guess:
Maybe the issue is simply that the network card has a new MAC address now? Try:

  -device e1000,netdev=net0,mac=52:54:00:4A:E7:F7
