Then you might be having a serius problem.
When functioning correctly, it should work just like before, only faster.

Unfortunately that page is somewhat outdated :P
For one, the drivers are activated by default (without the need for
any switch), but you can add NOGPLPV to deactivate it.

If you still have access to domU's xen vnc console, try checking to see if:
- you have two disks (C and D) when previoulsy there's only one (C)
- you have two active network card (look from device manager). XenNet
should be the only one active.

Note that booting to safe mode automatically disable GPLPV drivers, so
if you lost all access you might want to boot safe mode first, then
run bcdedit to create new entry with NOGPLPV.
