Just installed app-emulation/virtualbox-bin-4.2.12 if I launch VirtualBox from commandline (user) I get this error: NS_ERROR_FACTORY_NOT_REGISTERED (0x80040154) Running it from root, VirtualBox starts as expected. /tmp permissions seems ok (1777), as I seen in other bugreports something related to this. Reproducible: Always Portage 2.2.0_alpha179 (default/linux/amd64/13.0/desktop/kde, gcc-4.7.3, glibc-2.17, 3.9.5 x86_64) ================================================================= System uname:

Which user/group is the /opt directory assigned to? ls -ld /opt please. Did you add the user to the "vboxusers" group?
calvin ~ # ls -ld /opt drwxr-xr-x 1 root root 326 11 giu 17.21 /opt and yes, the user belongs to vboxusers But I have to say that suddenly virtualbox started to work. The only thing I've done is a reboot, so this make me wonder if something was out of order in kernel modules or something. anyway, sorry for the noise, hoping that the situation is fixed :) thanks for your answer !
I'm glad it works for you now. :-)
