Hello All,
Recently I have experienced an issue after vMotion a Virtual Machine. Virtual Machine has stopped responding to Ping response just after it got migrated to a new Host.
I did check VM Network and Other Virtual Machines which were hosted on same ESXi and Same VM Network and could not found any issue. Finally i took ssh and reviewed vmkernel.log file. and found below entries in the log file.
/var/log # cat vmkernel.log |grep 0x300000a

2017-11-09T12:26:40.822Z cpu24:32906)Net: 3354: disconnected client from port 0x300000a
Above logs clearly shows that VM Network did not resume after the vMotion on specified Port ID.
Resolution: In my case I updated Network Firmware and Drivers for NIC Card and it resolved the issue.
Thanks
