Thanks Pasi!

I think I have a pretty solid understanding of what works and what doesn't now.
It appears the actual drivers themselves tend to work reasonably
well.. most of the issue is the service within the guest tries to
initialize and finds xenstore dosen't contain the values it needs.
This causes it to restart 100s of times per second.. flatlining CPU. I
have disabled the service and observed disk IO and network performace
is very good but the shutdown monitoring doesn't work.
The solution to this is to use either the included xenstore client or
reverse engineer xs.dll in the Citrix XCP package..

I think I will post up a simple shutdown monitor based on the command
line xenstore_client that can be used with the Citrix drivers for
anyone that want's to go this route.
Atleast until I record xenstore traffic on XCP and Xenserver to
determine what Xen.org needs to write etc to make the usual service
work correctly.
