VirtualBox issues with Ubuntu 9.10

I am having issues with VritualBox in Ubuntu. When I launch it, I get an error about the virtual network adapter is not found, then when I close VB my Wallpaper disappears and all of my quicklaunch icons go to a red X. I am unable to find VB in Installed Software to uninstall and a reinstall does not help. Google is of no help with the error nor is the VB T/S site. I am at a loss and would prefer to not reinstall ubuntu. Thanks in advance.

hey SecurityN00b, the world of linux is a whole lot of fun aye? anyway it's not really documented anywhere when you install virtualbox, but all users that wish to use it must be a member of the virtualbox group, also occasionally the vboxdrv kernel module doesnt load which is the virtual network device it's referring to, it's simple enough to fix though, just open a command line such as gnome-terminal or xterm and type
#sudo modprobe vboxdrv

vbox upgrade to 3.1.4

hi person 1873

Many thanks for your simple solution. I've been tearing my hair out trying to rescue my virtual machines after upgrading to Ubuntu 9.1 and Virtualbox 3.1.4. Now I have some of my VMs available again. I say available because although I can now boot to the login screens, VBox seems to have forgotten my passwords and I cannot login as my normal user.

Any idea how I can login to a VM as root and fix this situation?

sorry mate, the logins should be handled by the various guest os's and not by virtualbox so you'll need to get support for those os's

if they're linux based hit your host key (usually right ctrl) and F1, this should drop you to a console from where you can login and switch user to root
