The startup/shutdown warning messages are transient so you can
ignore them.

I haven't used OpenVZ so I can't really help you with the ping
problem.
However, the following thread in the OpenVZ forum describes exactly
same problem:

http://forum.openvz.org/index.php?t=rview&goto=27520&th=5499

For the record, the answer seems to be that the dgramrcvbuf quota
needs to be increased.

Hope that helps,
