Maybe, I've found some issues on with SUSE: sle221 SLE221 SUSE Linux Enterprise Server 12 for SAP Applications
Course 01 - Overview of SLES for SAP Lab 1.1 - Familiarize yourself with the lab environment and the initial configuration of the Virtual Machines Lab Exercises

For the first lab:
On page 13:
tux@host:~> ssh virsh console server1
should be
tux@host:~> virsh console server1
On page 13:
CTRL-] should be related to the user keyboard
Like it is explained here https://www.cyberciti.biz/faq/howto-...-debian-linux/

Where should we share this kind of issues ?
For SLES courses in general, where should we share possible issues?
Thank you.
