Lab Controls
Click Create to build all of the virtual machines needed for the classroom lab environment. This may take several minutes to complete. Once created the environment can then be stopped and restarted to pause your experience.
When a lab is created, click Start to run all of the virtual machines in the classroom.
Click Stop to stop all the virtual machines from running. This will not delete your lab.
If you Delete your lab, you will remove all of the virtual machines in your classroom and lose all of your progress.
Virtual machine actions
Click Start to power on the virtual machine.
Click Shutdown to gracefully shut down the virtual machine, preserving disk contents.
Click Power off to forcefully shut down the virtual machine, while still preserving disk contents.
Click Open console to connect to the system console of the virtual machine in a new browser.
Auto-stop timer
The Red Hat Learning Subscription entitles you to set allotment of lab time.
To help conserving your allotted time, the lab environment uses automatic timers to stop or destroy your lab environment when the timer expires.
Click the Auto-stop button [+] to extend the time you would like to spend with the labs.
Click the Auto-destroy button [+] to add day(s) to the auto-destroy timer.
Auto-stop has a maximum of 11 hours, and auto-destroy has a maximum of 14 days.
Be careful to keep the timers set while you are working, so that your environment doesn't shut down unexpectedly.
We also suggest not to set the auto-timers unnecessarily high, which could waste your lab time allotment
