100% CPU time followed by system reboot

Code: Select all
Virtualbox: 5.0.10 r104061
Host: OS X 10.11.2 (64-bit)
Guest: Kali Linux (64-bit) & Alpine Linux (64-bit)
Having an issue where once a VM is started it consumes 100% CPU and then forces a system reboot. Killing the "Virtualbox VM" process results in a reboot as well.
How do I approach fixing this issue?

Alright, I solved this while sleeping
In case it helps anyone else, I had run
Code: Select all
sudo nvram boot-args=-no_shared_cr3
and after running
and rebooting Virtualbox started working as expected.

Not trying to be mean or embarrass this user but this post is nonsense.
the first command…
Code: Select all
sudo nvram boot-args=-no_shared_cr3
Has nothing to do with running VMs and was used to try and thwart zero-day exploits. It also causes a performance hit on the system. This has already been addressed in OSX 10.11.2
The second command isn't even the correct syntax.
Lastly, CPU time is not measured by a percentage.
If I were an OSX user, which I am, I certainly wouldn't run the commands.
Just to add, I have a Kali 2.0 guest, it's CPU Use is 3% on average and certainly never caused a system reboot. It's just a Debian based distro.
