FreeBSD, VBox, mouse integration

[asf8g 9hf32]

Hello,

I'm using VirtualBox. Host OS is FreeBSD, guest OS is FreeBSD(amd64) too.
I'd like to integrate mouse from guest and host(I don't want to use right
ctrl to free mouse from guest).
I'm using vbox guest additions to do it. I have loaded drivers(vboxguest
and vboxvideo).My rc.conf has lines

vboxguest_enable="YES"vboxservice_enable="YES"

but mouse isn't integrated.

Could you tell me what to do to integrate mouse ?

Thanks,

Lukas
