I'm using Virtualbox on Ubuntu 14.04 x64. I found many services loaded at startup related to vbox

  • vboxautostart-service
  • vboxdrv
  • vboxballoonctrl-service
  • vboxweb-service

I disabled all of them and now the startup seems faster. Also, I tried to launch VB with all the services disabled and VB runs without fails. So, what are these services? What they do? Can I safely run VB without launching them?

This is what I found online - vboxautostart-service: manage some autostart options like configuration file, deny access to users, ... - vboxdrv: the only one needed if you want to run virtualbox in the traditional way! - vboxweb-service: needed if you want to use phpVirtualBox to access your VB machine from a remote terminal - vboxballoonctrl-service:

Starting with VirtualBox 4.0.8 a new host executable called VBoxBalloonCtrl is available to automatically take care of a VM's configured memory balloon (see Section 4.8.1, “Memory ballooning” for an introduction to memory ballooning). This is especially useful for server environments where VMs may dynamically require more or less memory during runtime.

VBoxBalloonCtrl periodically checks a VM's current memory balloon and its free guest RAM and automatically adjusts the current memory balloon by inflating or deflating it accordingly. This handling only applies to running VMs having recent Guest Additions installed.
