We are having a strange issue with vboxdrv module in my workplace.
Most of the host machines are Debian Wheezy, and we run some Windows virtual machines, built in VirtualBox, to access Windows-only programs.
However, these machines are now crashing with kernel panic errors. The kernel is tainted due to vboxdrv module. I managed to solve this issue by updating VirtualBox to last version, but one of those still panics when running Java with the module loaded. I couldn't find anything on the web about this weird problem.
Has anyone already faced this issue? Any hint to how can I solve?
UPDATE: I just realized it always crashes showing a kernel taint flag which may not show up when cat'ing
/proc/sys/kernel/tainted. Also, sometimes it seems to lack refreshing of kernel loaded modules, even after reboot, needing a second reboot to work properly.
