SSH timeout on macOS VMs with shared networking

[gtestault]

Here are some snippets from the debug vagrant log

DEBUG ssh: == Net-SSH connection debug-level log END ==
 INFO ssh: SSH not ready: #<Vagrant::Errors::NetSSHException: An error occurred in the underlying SSH library that Vagrant uses.
The error message is shown below. In many cases, errors from this
library are caused by ssh-agent issues. Try disabling your SSH
agent or removing some keys and try again.

If the problem persists, please report a bug to the net-ssh project.

ok this was probably a collision with other networks. Worked after I used link-local subnet for the shared network
