VMware ESX : Failed to connect ethernet0

By | February 11, 2012

You may encounter this error on VMware ESX / ESXi server on a guest event console (on vSphere Client) :

Error message from host.domain.tld: Failed to connect ethernet0

Of course, the guest system have no functional network.

This probably happen if you actually rename a Virtual Network that was previously used by the guest. Changes does not apply automatically on guests.

To solve this, simply do :

– Go to Summary tab > Click on Edit settings
– Click on Network adapter 1 > and select the proper Network label inside the Network connection section.
