Detail

In cases where it is hard/impossible to install VMware Tools/open-vm-tools during OS auto installation, the vsphere-iso builder will wait for an IP, that will never be reported. In this case I would like to skip waiting for an IP and instead wait for SSH (maybe in combination with pause_before_connecting).

The docs mention the parameter ip_wait_address, but I do not understand how to disable it. Passing null leads to the default filter and passing an empty string leads to accepting all IP addresses, but it still has to be an IP address.

How can I skip waiting for an IP address and let the communicator wait immediately?

Suggestion

Add a note to ip_wait_address on how to disable the wait mechanic.

Hi @mbx64 👋🏻 - I'll take a look at this and provide and update hopefully this week or next along with a supporting PR for the documentation update.
