AF, OK, so we're getting close. Previously you said DNS is fine :D

Can you run this on the PV domU AND a physical machine on the same
network, and paste the results :
- nslookup www.microsoft.com
- ping www.microsoft.com
- the error message when you try to access www.microsoft.com

Also if possible, try setting up Bind
(https://www.isc.org/software/bind), and run "dig +trace
microsoft.com". It should print the DNS query path. Here's the result
from my PC:

$ dig +trace microsoft.com

Probably you're having network problems connecting to ns*.msft.net?

That pretty much ruled out PV driver problem.

If ALL DNS lookup fails, I'd say it's probably network issue. But
since it's only microsoft.com, I'm suspecting problem with your
existing DNS server or connection to MS' name server.
