When I try to run the 4.0.2 version of VirtualBox OSE on Fedora 14, I get the following error:
Failed to open a session for the virtual machine aiur2b.
Failed to load VMMR0.r0 (VERR_SUPLIB_OWNER_NOT_ROOT).
Unknown error creating VM (VERR_SUPLIB_OWNER_NOT_ROOT).
I've been running VirtualBox-OSE for over a year now on this system without any problems. No settings have changed. Yet suddenly OSE 4.0.2 doesn't want to open a VM anymore. I've tried it on my Fedora VMs, my Slackware VMs, Windows XP, ubuntu and Windows 95 VMs, none of them work now.
Is there any way possible to downgrade VirtualBox-OSE back to a version that doesn't come up with these errors? Thanks!
