Winson,

You will need to provide more info on the crash, as I don't know what 
might cause VNET to fail.  To the best of my knowledge, VNET is agnostic 
  to the type of device you are using for networking.  Of course, it 
does care about protocols.  Are you using something other than IPv4 for 
Layer-3 or some other non-standard/new Layer-4 protocol?

You can certainly disable VNET.  You can do so by de-installing its rpm 
(rpm -e vnet) or by disabling it from being invoked upon boot by using 
chkconfig (chkconfig --del vnet).
