 You can reboot the VM, or more simply just restart the network (in the VM), with the following:\\ ''sudo service network restart''
+==== Problems when mounting LSCE disks in the VM ====
+When your host is connected **to the LSCE network**, your VM should be able to access/mount directly all the LSCE disks in the VM (e.g., you can type ''cd /home/users/your_login'' directly in local terminal of your VM to access your LSCE home directory).
+If you get an error message, there is probably a kerberos related problems... You can try typing ''klist'' and ''kinit'' in your local terminal and see if you can then access the LSCE disks!
+If you still can't mount the disks, check the status of autofs, and restart it if necessary:
+  * ''sudo systemctl status autofs''
+  * ''sudo systemctl start autofs''
