Hmm,
two questions from me.
I think there is 10GbE link reported in Windows gplpv 0.11.0.322 driver.
Let say I have two virtual Windows running on XEN and they are in bridge with 
1GbE physical NIC.
Will the Windows talk to each other on 10GbE thru the bridge?
What should I do to give them 10GbE access to local samba server?
