Unable to ping www.cnn.com or other sites besides www.bing.com.

Hi all, this is my problem.  Whenever I try to ping www.microsoft.com or www.cnn.com from inside of an OpenLogic CentOS 6.3 64-bit virtual machine... nothing happens.  When I do a traceroute, also nothing.

$ traceroute www.microsoft.com
traceroute to www.microsoft.com (65.55.57.27), 30 hops max, 60 byte packets
