To support the VNC connection to the cloud instance desktop GUI, create an SSH tunnel to the cloud instance. Before making the VNC connection, an SSH tunnel is established to support the VNC connection. To access the desktop GUI of the Oracle Linux cloud instance server running VirtualBox, you will make a VNC connection from the Luna desktop to the cloud instance. Therefore, you might want to step away while this runs and promptly return to complete the lab. The deployment takes approximately 15-20 minutes to finish after launch. Information: The free lab environment deploys a running Oracle Linux cloud instance with Oracle VM VirtualBox and Tiger VNC installed. As this lab will not be using Oracle Cloud Infrastructure console, you do not not need the information regarding Logging into the Oracle Cloud Console. Note: When using the free lab environment, see Oracle Linux Lab Basics for connection and other usage instructions. Create a SSH Tunnel to an Oracle Linux Server Connect to the Lab Desktop GUI To support an SSH connection to the new instance terminal, public and private authentication keys have already been created and set to the instance and cloud console. Oracle VM VirtualBox and Tiger VNC software is automatically installed to the instance when this lab is launched. Virtualization support has been enabled in this instance. Setup Lab EnvironmentĪ new Oracle Linux 8 instance called ol-vbox is automatically provisioned and started when this lab is launched. Install VirtualBox Guest Additions to a Virtual Machineīasic experience of working with Oracle Linux command line and its desktop graphical user interface.Use VirtualBox to create a new Oracle Linux virtual machine.Install Oracle VM VirtualBox to an Oracle Linux cloud instance.Connect to the cloud instance Server GUI Desktop with VNC.Create a SSH tunnel to an Oracle Linux Server instance.There are free videos available demonstrating more functions of Oracle VM VirtualBox as well as its integration with Oracle Cloud Infrastructure, you can find a link to them in the For More Information section at the end of this lab. You can read more detailed information about Oracle VM VirtualBox at this documentation link: Oracle VM VirtualBox Documentation You will install Guest Additions to a VM which will provide closer integration between host and guest and improve the interactive performance of the guest system. You will practice implementing nested virtualization in VirtualBox to support the creation of virtual machines on the cloud instance. It steps you through creating a new virtual machine using VirtualBox installed on the cloud instance, and installing the Guest Additions to the new VM. This hands on lab guides you through installing VirtualBox and its extension pack on an Oracle Linux cloud instance. VirtualBox can be installed and run on various platforms, from a standalone laptop to a cloud instance. Oracle VM VirtualBox allows the simple and fast creation of virtual machines (VM) supporting a wide variety of operating systems. Use Oracle VM VirtualBox on Oracle Cloud Infrastructure Instances Introduction When completing your lab, substitute these values with ones specific to your cloud environment. It uses example values for Oracle Cloud Infrastructure credentials, tenancy, and compartments.This tutorial is available in an Oracle-provided free lab environment. ![]()
