| + | ===== Using shared folders ===== | ||
| + | |||
| + | * The shared folders make it possible for the guest to access directories of the host | ||
| + | * The guest additions have to be installed in order to use the shared folders! | ||
| + | * The Linux account on the guest that will use the Shared Folders has to be a member of the //vboxsf// Linux group | ||
| + | |||
| + | ==== Configuration and use ==== | ||
| + | |||
| + | * Shut down the VM if it is running | ||
| + | * Select the VM in the //VB Manager// window | ||
| + | * Settings => Shared Folders | ||
| + | * Click on the '+' sign and fill the fields of the //Add Share// window | ||
| + | * Folder Path: e.g. ''H:\Scratch\<user_login>'' | ||
| + | * Folder Name: e.g. ''Scratch'' | ||
| + | * Auto-mount: selected | ||
| + | * The newly configured folder will appear in the //Machine Folders// list | ||
| + | * Start the VM and login | ||
| + | * Type ''df -h'' and check that the defined shared folder appears as /media/sf_Scratch | ||

| You can reboot the VM, or more simply just restart the network (in the VM), with the following:\\ ''sudo service network restart'' | 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'' | ||

| + | |||
| + | ==== Accessing the Linux system messages and logs ==== | ||
| + | |||
| + | If something is not behaving as it should, it can be useful to check the system messages! | ||
| + | |||
| + | * **dmesg**: //print or control the kernel ring buffer//\\ ''dmesg -Hw'' | ||
| + | * ''sudo tail -f /var/log/messages'' | ||
