how to find out which version of OpenStack is installed
OpenStack is installed in group of servers. How do we know what version of OpenStack is installed (Havana or IceHouse etc)? Will it be in some file?
Is it logical to talk about which version of openstack is installed? Because - I am also assuming that we can use few components from one release and other components from different release and deploy a openstack setup.
Also, let me know, is it possible to know the version name through REST API?
