Chapter 4. Configure Public Key based SSH Authentication without a password
From the first virtualization host, configure Public Key based SSH authentication for the root user without a password to all virtualization hosts using the FQDN associated with the management network. This includes authentication from the first host to itself.
RHHI for Virtualization expects key-based SSH authentication without a password between these nodes for both IP addresses and FQDNs. Ensure that you configure key-based SSH authentication without a password between these machines for the IP address and FQDN of all storage and management network interfaces.
