The full messages is:
VirtualBox: supR3HardenedMainGetTrustedMain: dlopen("/usr/lib/virtualbox/VirtualBox.so",) failed: VBoxVMM.so: cannot open shared object file: No such file or directory
The VBoxVMM.so file is in the same directory as the VirtualBox.so file. Also:
ldd /usr/lib/virtualbox/VirtualBox.so linux-gate.so.1 => (0x00bec000) libXinerama.so.1 => /usr/lib/libXinerama.so.1 (0x00110000) libGL.so.1 => /usr/lib/libGL.so.1 (0x00961000) VBoxVMM.so => /usr/lib/virtualbox/VBoxVMM.so (0xb7625000)...
shows its in the correct dir.
This thread suggests it has something to do with glibc: https://bugzilla.redhat.com/show_bug.cgi?id=645500
This thread suggests it has been fixed: https://bugzilla.rpmfusion.org/show_bug.cgi?id=1465
If all of this information is correct will it soon become part of the FC13 yum update stream?
