Openstack deployment randomly fails because Undercloud vm lacks resources

Solution In Progress - Updated -

Issue

  • In this situation we see random heat resources failing during deployment. Sometimes resources like Management network ports that are not even used.

  • Notice 500 errors with the overcloud nodes attempting to connect to the undercloud.
