Virtual machine loses network connectivity after a migration from an ESXi 5.1 host to an ESX 4.1/ESXi 5.0 host (2038301)

Symptoms

After performing a vMotion of a virtual machine from an ESXi 5.1 host to ESX 4.1 or an ESXi 5.0 host, you experience these symptoms:
  • The virtual machine gets disconnected from the network
  • Virtual machine loses network connectivity when using VDS
  • Virtual machine loses network connectivity after the migration when using VDS dvPortGroup
  • Virtual machine regains network connectivity if it is migrated back to ESXi 5.1
  • In ESXi 5.0 log files, you see entries similar to:

Resolution

This issue has been resolved in ESXi 5.0 Patch 5(Build 1024429).
For details see: VMware ESXi 5.0, Patch ESXi500-201303401-BG: Updates esx-base (2044374).

To work around this issue in earlier builds, change the port group of the virtual machine to another network and then revert it to the original port group.

Alternatively, power off the virtual machine which is having the issue on ESXi 5.1, migrate it to ESX 4.1, and then power on the virtual machine in ESX 4.1. This resolves the network connectivity issue.
