Description: 
-------------

Not always reproducible - this error happened to me and to others, while following RDO-manager steps - when attempting to install RDO-manager on virt-environment - during the execution of the command 'instack-install-undercloud'. 

In my case I just re-provision the environment and tried to reproduce again, but couldn't reproduce.  although when it happened to other on different environment I've decided to report this Bz.      

Steps (not always reproduce) :
-------------------------------
1) follow the guide steps to deploy undercloud : https://repos.fedorapeople.org/repos/openstack-m/instack-undercloud/internal-html/install-undercloud.html


Results: the following error appear during the execution of the command 'instack-install-undercloud'.
