Here is the scenario....
Was upgrading a two host cluster from 4.1 to 5.0. The upgrade of the first node completed without issue. The upgrade of the second host did not complete successfully and I ended up having to run fresh install. Here is the symptom I anow dealing with on the second host...certain VMs (not all) being host on this host do not have network connectivity. Other VMs, residing on this same host, do have network connectivity. When the VMs that are experiencing the connectivity problem are migrated to the first host, they regain network connectivity. The vSwitches are standard and are setup exactly the same on both nodes. As mentioned earlier, some VMs have no network connectivity issue when residing on the second node.
Another odd symptom I have seen with the vm vswitch is that when certain vnics are adds to the switch, they cause brief network interruptions. That is to say is I am pinging a vim, I may get five good replies and then two time outs. With the questionable nics removed, replies are consistent.
The configurations of the physicla swithc ports have remained consistent. The management vswitch works properly.
Any ideas or suggestions guys...other than call support?
