I don't know if this is still a problem in 3.0.2, but I know that 3.0
had issues with ip checksum offload within the domU when it's using a
bonded virtual nic.

bitty:~ # ethtool -k eth0
Offload parameters for eth0:
Cannot get device rx csum settings: Operation not supported
Cannot get device scatter-gather settings: Operation not supported
Cannot get device tcp segmentation offload settings: Operation not supported
rx-checksumming: off
tx-checksumming: on
scatter-gather: off
tcp segmentation offload: off

Until I issued:
ethtool -k eth0 tx off

I could only ping to/from the domU, and udp/tcp packets just didn't 'work'
