2.17. Using noVNC to Access Virtual Machines

You can use your browser to access the VNC console of VMs created by Satellite.

Satellite supports using noVNC on the following virtualization platforms:

Prerequisites

You must have a virtual machine created by Satellite.
For existing virtual machines, ensure that the Display type in the Compute Resource settings is VNC.
You must import the Katello root CA certificate into your Satellite Server. Adding a security exception in the browser is not enough for using noVNC. For more information, see the Installing the Katello Root CA Certificate section in the Administering Red Hat Satellite guide.

Procedure

On the VM host system, configure the firewall to allow VNC service on ports 5900 to 5930:

On Red Hat Enterprise Linux 6:

iptables -A INPUT -p tcp --dport 5900:5930 -j ACCEPT
service iptables save

# iptables -A INPUT -p tcp --dport 5900:5930 -j ACCEPT
# service iptables save
