- * '''Tickless Linux timer''': !VirtualBox currently does not work well on Linux kernels which where configured with tickless timer support (CONFIG_NO_HZ). We are investigating the problem but in the meantime you should disable the tickless timer by disabling the config option or by adding 'nohz=off' to the Linux kernel command line.
+ * '''Tickless Linux timer''': !VirtualBox currently does not work well on Linux kernels with tickless timer support (CONFIG_NO_HZ enabled).

  * If you get a message saying '''"!VirtualBox kernel driver not accessible, permission problem"''' when starting !VirtualBox right after installation, make sure that your user account is listed in the `vboxusers` group. The installation takes care creating that group, but you will need to manually add all users to it that should be allowed to run !VirtualBox. As root, for each such user, run `usermod -G vboxusers -a <userid>`. If any of the affected users are currently logged in, they need to log out for the changes to take effect. In case any user already attempted to start !VirtualBox before logging out (which launches the VBoxSVC service process with incorrect permissions), that user additionally needs to run `VirtualBox shutdown` from the command line to terminate the service. This solves the permission problems. (Alternatively, a reboot will help as well.)
