intermittent AIO error: Timeout (7s) waiting for privilege escalation prompt

[Markos Chandras]

During my effort to add openSUSE support to the AIO repository, I noticed the following intermittent issue

[aio1]: FAILED! => {"failed": true, "msg": "Timeout (7s) waiting for privilege escalation prompt: "}

This happens mostly in the os_nova role tasks

However, googling for it reveals that people have reported it in the past as well

One suggested workaround is to use

[defaults]
timeout = 30

in /etc/ansible/ansible.cfg

but that doesn't seem to help.

    Vagrantfile: Increase VM memory size to 12G

    Running AIO on Vagrant results in the entire 8G of memory being used.
    This makes the VM really slow after a while and as a result of which
    various services may start to fail due to timeouts. It's best to
    increase the VM memory to 12G in order to make testing on Vagrant
    smoother.
