did you # kldload vboxdrv as root?

 

[SIFE]

yes .

I had something like that after update/upgrade - forgot what exactly but the problem was gone after rebuilding vbox.

 

[SIFE]

well ,i rebuild it many times but no hope .

I just now ran into this with the 3.1.8 -> 3.2.2 upgrade. I kldunload'ed all 3 "vbox" modules and loaded them back in and was able to restart my VMs without issue.

 

[SIFE]

i did all what did you suggest but no chance to start it ,even i upgrade to 8.1-PRELEASE .

Is the error still the same (Undefined symbol "atan2l")?
What does this show:# ls /lib/libm.*
# ldd /usr/local/lib/virtualbox/VBoxREM32.so
What version of FreeBSD did you have before 8.1-prerelease?
Did you rebuild virtualbox-ose-kmod after upgrading FreeBSD?
