2017-11-11 03:31:20 -0500 commented question Adding existing KVM to openstack

I am not sure what you try to achieve, but openstack is not just another layer to retrieve vm information, it is a whole ecosystem with several components that are strongly connected with each other.

For your task I would suggest that you use a monitoring tool like nagios and/or check_mk
