/etc/init.d/vboxdrv restart fixed the problem for me as well (at least for this session).
It looks like runlevels 2 3 4 5 to me. I think this is the relevant section of /etc/init.d/vboxdrv : ### BEGIN INIT INFO # Provides: vboxdrv # Required-Start: $syslog # Required-Stop: # Default-Start: 2 3 4 5 # Default-Stop: # Short-Description: VirtualBox Linux kernel module ### END INIT INFO -- [intrepid] failed to power virtual machine message "spawning session..." freeze https://bugs.launchpad.net/bugs/272064 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
