It appears you are using the VboSVGA video card with 3D acceleration turned on:

00:00:00.133502   3DEnabled        <integer> = 0x0000000000000001 (1)
....
00:00:00.133507   VMSVGA3dEnabled  <integer> = 0x0000000000000001 (1)
00:00:00.133508   VMSVGAEnabled    <integer> = 0x0000000000000001 (1)
00:00:03.200589   VMSVGAPciId      <integer> = 0x0000000000000001 (1) 
^this strikethroughed line is not in the log, so VboxSVGA, not VMSVGA

This video card is new, and is still getting the bugs worked out of it. 3D acceleration won't be used while running headless. Could it be causing the crashes? Turn off 3D acceleration and see what you get.

Good call 'scottgus1', VBoxHeadless and 3D doesn't make sense, up until a while ago it would crash the VM at startup.

Another thing you should correct in your VM Settings:

00:00:00.133168 NumCPUs <integer> = 0x0000000000000004 (4)
00:00:00.299737 CPUM: Physical host cores: 4
00:00:00.299993 Full Name: "Intel(R) Core(TM) i7-4850HQ CPU @ 2.30GHz"

You have assigned all your CPUs to the VM. The host is going to run low on resources, since VirtualBox cares about physical processors (cores), not logical ones (threads). Just check the link for your CPU above, and make sure you read the text in the "?" next to the "# of Cores" and "# of Threads" in that Intel page...

Thanks for your help, I have corrected the settings, disabled the graphics controller completly and fixed the CPU too ... Have overseen that because the setting is still in the "green area" and shows an max value of 8.

Let us know how it goes, so we can mark the thread appropriately, if it works...

It works.
Thanks again for your help.
