quickly crash under load

--- Description ---
I have been working with a small team testing VirtualBox on FreeBSD 11.2 as
well as the 12.0beta3 and in both cases we see curious problems. In the case
of vbox on 11.2 we can create a FreeBSD 11.2 virtual guest and then even=20
install the extension pack from the pkg repo.  However any real cpu load=20
will result in the virtual machine to crash for reasons unknown. We tested
this with some trivial scp of a set of 1GB files and within 60 secs the=20
virtual machine would crash.=20

In the case of 12.0b3 we used an ovf export from the 11.2 system and the=20
import process went smoothly. The vnc connection will not work at all so
there is no way to "see" a virtual machine console. Regardless we could
boot the virtual machine and try the same sort of tests only to get the
same result : a FreeBSD 11.2 virtual machine crashes within 60 to 90 secs
of any cpu load.=20

The hardware is fairly top of the line Xeon based server hardware with=20
Adaptec(MicroSemi) 8000 series SAS controllers and 128G of memory on
the host systems. No amount of tweaking of the virtual machine conf=20
would bring stability.=20

Not sure how to proceed but there is a multitude of bugs here.
