Detailed Application Settings

VirtualBox

• See virtual machine configuration log.
• Installed with apt (original version 4.2.8)
• VirtualBox is launched as user root (because it seems that only the current user and root can access PulseAudio in a same X session — see [1])
• Allow user beq06659 to launch VirtualBox through user root. Add to /etc/sudoers:

beq06659	ALL=NOPASSWD: /usr/bin/VirtualBox

• Helper script to add to e.g. ~/bin :

#First allow user vbox to connect to X11
#xhost +SI:localuser:vbox
#sudo su vbox -c /usr/bin/VirtualBox&

#New config - run VirtualBox as root to allow sound
sudo /usr/bin/VirtualBox&

• Create a launcher in ~/.local/share/applications/virtualbox-root.desktop

#!/usr/bin/env xdg-open
