In future labs, you will have to run your VMware Workstation application to boot-up your CentOS 7 RHEL9 host VM.Usually, you are NOT required to use this menu (unless you need to "force-off" the c7host7 r9host machine, but should only be performed if you cannot normally shut-down the c7host r9host VM from the OS.

If you have performed the lab correctly, then you will get a series of <b><code><span style="color:#66cc00;border:thin solid black;font-size:1.2em;">&nbsp;OK&nbsp;</span></code></b> messages and you can proceed with the SIGN-OFF for lab1. On the other hand, if there were errors, then a <b><code><span style="color:#ff0000;border:thin solid black;font-size:1.2em;">&nbsp;WARNING&nbsp;</span></code></b> message will appear with general suggestions that you will need to fix on your c7hostVM r9hostVM in order to have your professor sign-off in this lab in order to proceed to the next lab.
