  • n-cond is the nova-conductor service, which acts as an intermediary between the compute service and the database.
  • n-novnc is the novnc proxy, which is instrumental in providing console access through the web interface.
  • n-xvnc is the nova xvpvncproxy service, which is similar to the novnc service but uses a java client for console access rather than the browser.

is it necessary to include n-novnc while installing devstack? because my devstack installation stops and says

echo 'Error: Service n-novnc is not running'

Error: Service n-novnc is not running
