[RHEVM shell (disconnected)]# connect --url "https://rhevm.example.com:443/api" --user "admin@internal" --password 'redhat'

• Not sure about the location of the CA certificate file and how it needs to be passed to connect to the rhevm-shell.
• Tried providing the CA certifcate file as /etc/pki/ovirt-engine/certs/engine.cer and then tried to connect.
