A Red Hat training course is available for Red Hat OpenStack Platform

B.5. SSH and Virsh

The director can access a host running libvirt through SSH and use virtual machines as nodes. The director uses virsh to control the power management of these nodes.

Important

This option is available for testing and evaluation purposes only. It is not recommended for Red Hat OpenStack Platform enterprise environments.
pm_type
Set this option to pxe_ssh.
pm_user, pm_password
The SSH username and contents of the SSH private key. The private key must be on one line with new lines replaced with escape characters (\n). For example: 
-----BEGIN RSA PRIVATE KEY-----\nMIIEogIBAAKCAQEA .... kk+WXt9Y=\n-----END RSA PRIVATE KEY-----
Add the SSH public key to the libvirt server's authorized_keys collection.
pm_addr
The IP address of the virsh host.

Additional Notes

  • The server hosting libvirt requires an SSH key pair with the public key set as the pm_password attribute.
  • Ensure the chosen pm_user has full access to the libvirt environment.
