First time I’ve encountered this issue in my environment after a DRS initiated vMotion of a VM. I’ve noticed that the VM’s network card is disconnected and whenever I tried to connect it, the Invalid Configuration for device ‘0’ error pops up. From the looks of it, vMotion had a bandwidth issue but it did migrate successfully after another attempt.
This exact issue is documented in KB 2014469 and although vSphere 5.5 is not in the product list, I gave it a try to see if it will resolve this issue.
I did Option 1 of the KB article which is to move the VM into a different and unused dVPort. From the screenshot below, my VM Win2K8R2 is using port 104 of distributed switch vDS-DMZ.
To change this, edit the VM setting and highlight the network adapter. Under network connection, click Switch to advanced settings. In the Port ID box, change the Port to a new unused port. In the screenshot below, I changed the port from 104 to 105
