--- Comment #11 from Jason W. Bacon <jwb@freebsd.org> ---
To patch in a workaround, I think we would need to insert

vboxmanage setproperty hwvirtexclusive off

before a VM is started by any method.  There are multiple ways to launch a VM
from the command line (VirtualBox, VboxHeadless, VBoxManage startvm, etc.)  I
wonder if they all lead to a single point in the code where the VM process is
started, or if the start code is replicated in multiple places.  This will
require a little digging...
