Summary     : OpenStack Nova Virtual Machine control service
Description :
OpenStack Compute (codename Nova) is open source software designed to
provision and manage large networks of virtual machines, creating a
redundant and scalable cloud computing platform. It gives you the
software, control panels, and APIs required to orchestrate a cloud,
including running instances, managing networks, and controlling access
through users and projects. OpenStack Compute strives to be both
hardware and hypervisor agnostic, currently supporting a variety of
standard hardware configurations and seven major hypervisors.

This package contains the Nova service for controlling Virtual Machines.

  I'm not  convenienced about the error message. I'm interested in
  generic sort of error message where it says glance is down instead of
  server is down(which does not make any sense in this case).

  Summary     : OpenStack Nova Virtual Machine control service
  Description :
  OpenStack Compute (codename Nova) is open source software designed to
  provision and manage large networks of virtual machines, creating a
  redundant and scalable cloud computing platform. It gives you the
  software, control panels, and APIs required to orchestrate a cloud,
  including running instances, managing networks, and controlling access
  through users and projects. OpenStack Compute strives to be both
  hardware and hypervisor agnostic, currently supporting a variety of
  standard hardware configurations and seven major hypervisors.

  This package contains the Nova service for controlling Virtual
  Machines.
