Receently converted RH Linux 7.1 and that is working okay. I added the default network settings using a flexible adapter and it finds the NIC without problems. I checked the network IP default gateway no problems there.
Other Guest Hosts on that VM are working using that portgroup so its not the esx server.
I do get this error when I try to do a test ping on the LAN
eth0: trasmit timed out; status 0073
