To raise or lower the guest process execution limit, either the guest property "/VirtualBox/GuestAdd/VBoxService/--control-procs-max-kept" or VBoxService' command line by specifying "--control-procs-max-kept" needs to be modified. A restart of the guest OS is required afterwards. To serve unlimited guest processes, a value of "0" needs to be set (not recommended).
