After restarting the host (Ubuntu on Dell Vostro 420), Virtualbox is working fine. FYI this is what I remember doing -- install Virtualbox from Ubuntu Software Centre install Windows XP windows screen doesn't fill available window couldn't access usb couldn't share directories run $sudo adduser humphrey vboxuser usb now accessible run $sudo adduser humphrey vboxuser fails with "group vboxsf does not exist" tick "guest additions" in "X86 virtualization solution - base binaries" in Ubuntu Software Centre & click <apply changes> no effect remove & reinstall "X86 virtualization solution - base binaries" virtualbox reports error "Kernel driver not installed (rc=-1908)" -- I decide to explore first before reinstalling virtualbox from the ppa at launchpad -- I find references to "insert guest additions CD image" I find the entry on the "devices" menu of virtualbox & execute it I can share directories -- I don't remember at what points or how often I rebooted the virtual machine, virtualbox and/or the host I hope this helps
