About the kernel: I don't have anything special.

USE-flags:

[I] app-emulation/virtualbox

     Installed versions:  4.3.32{tbz2}(03:46:09 PM 11/25/2015)(additions alsa 
extensions java opengl pam pulseaudio qt4 sdk udev -doc -headless -libressl -
python -vboxwebsrv -vnc ELIBC="-FreeBSD" PYTHON_TARGETS="python2_7")


What does " dmesg " have to say?

For me:
% dmesg | grep -i vbox
[  165.950507] vboxdrv: Found 8 processor cores.
[  165.950787] vboxdrv: fAsync=0 offMin=0x1fe offMax=0xa4f9
[  165.950828] vboxdrv: TSC mode is 'synchronous', kernel timer mode is 
'normal'.
[  165.950829] vboxdrv: Successfully loaded version 4.3.32 (interface 
0x001a000b).
[  165.978641] vboxpci: pci-stub module not available, cannot detach PCI 
devices
[  165.978643] vboxpci: IOMMU found


I actually updated to 4.3.32 yesterday. VMs are still starting.

How exactly are you starting the VMs?

I do it all with the GUI: /usr/bin/VirtualBox
