Hi!
I have seen this problem several times in the last days: When trying to connect my local DVD drive through vSphere Client with a VM, the CD/DVD button shows "connecting..." but never actually finalizes the process. I think yesterday I was able to solve this problem only by powering off the VM, removing the device from the configuration and adding a new one. Now even if I remove the device, power on the VM (i.e. the CD/DVD button is greyed out because there is no device), power off the VM and add a new drive, then power it on again, the drive is still shown as "connecting..."
Is this a known problem? And how do I get out of this situation?
