I am experimenting with virtual box. One of my problems is that the mouse cursor only works within the box. How can I make it work both with the actual OS too and the virtual box at the same time?

Right CTRL key to release the mouse and keyboard.
Documentation on the host key is here. <-- Credit to Takkat on the link

Install guest additions for transitions without manually releasing the keyboard/mouse.

right CTRL doesnt do anything. I really dont know why not. Is there a way to turn off the auto capture even before powering up the vbox? – Elysium Mar 22 '12 at 13:33
For me, it doesn't auto-capture without guest additions. It only captures if I click in the box. Did you set a custom host key? It should be displayed in the bottom right of the window. – RobotHumans Mar 22 '12 at 13:34
ty - I may have customized this some time ago. See for more – Takkat Mar 22 '12 at 13:51

To get your mouse cursor to work, you simply need to press the Ctrl key on the right side of the keyboard. If you don't want to keep pressing Ctrl to release the mouse cursor every time, simply install the VirtualBox Guest Additions by clicking on Devices > Install Guest Additions. When you do this, you may need to mount the virtual cd-rom drive by using the following command:

$ sudo mount /dev/scd0 /mnt/cdrom

Then run the shell script to install the Guest Additions.

Firstly, do right+ctrl. You will be out of virtual machine then right-click on mouse sign which is down-right side on virtual machine. Disable mouse integration.
