Unable to log into ISO boot on KVM guest

I currently have a server running Ubuntu Server 16.04LTS and want to use RancherOS as my guest for my VM to run specific containers. However, after I use virt-installer with the RancherOS ISO (v0.6.1), it boots up but when I try to log in via SSH (I am using an SSH for the host session) from the host to the guest with rancher/rancher, it fails authentication.

Am I missing something?
