 ### The VM starts and it shows an error
 
-#### eth1
+#### Pinging 8.8.8.8 fails
+
+Your VM cannot access internet. It is probably due to your computer that is not connected to internet or your traffic is filtered. Try to reconnect to internet or change of network provider and recheck.
+
+#### DNS resolution fails
+
+If you can ping 8.8.8.8 is ok and the DNS resolution fails, it is a strange problem. It means that the DNS server embedded in VirtualBox cannot send DNS request outside. It should not happen. Try to change of network provider.
 
 ### Other problems
 
 #### Cannot exit the mouse from the VM
 
 By default the key "Ctrl" on the right, asks Virtualbox to exit from the VirtualBox window. If your keyboard has no right Ctrl key, you should customize the key in the preferences of Virtualbox.
+
+#### The screen of the VM is very small
+
+It is really difficult to read the screen !
+
+You can increase the screen size by going into the menu:
+
+Screen > Virtual screen number 1 > Resize to 125%
