This looks like a vbox issue, the driver did not properly locked the object passed to the vm_page_alloc_contig(). If you want this fixed, you probably need to look up the code yourself, compiling the vbox kld with debugging, finding the offending call to vm_page_alloc_contig() and looking around it to see which object is passed and why it is not locked.
