We have upgraded vcenter from version 4.1 to 5.0 without any issues
After upgrading the first of 11 ESXi hosts we have a problem with network connectivity.
Everything has been configured as before but one of the network adaptors is showing as on "stand by"
When i try to migrate a live virtual machine to the upgraded Host, the migration works fine but the VM instantly looses network connectivity.
Any idea what i am missing?
