Hello Wayne,

To fix this turn off all offloading on both the guest and the host NIC. 
You can see what offloading is active with the following command.

ethtool -k eth0

The -K will let you modify them to off.  I believe the most recent kernel 
from the repo might also solve this however from what I read it should be 
off anyway.
