virtualbox - Why does virtual box vboxheadless process using Vagrant use 100% of my cpu?

Question

So I'm using a couple vagrant boxes and when i have them up, "sometimes/randomly" it starts to take up 100% cpu on my OS X machine and i have no idea whats causing it. I can ssh into the vmachine and check the load and it's at 0 sot its not something thats running in the box.

The only way I can fix this is if i suspend it and resume it, then it goes away until randomly it starts to happen again. Sometimes hours later, sometimes days later.

The only thing I can think of is it might be because i'm using nfs mounts within my virtual machine to access my projects, but i'm not sure yet. Any ideas?

EngineerCoder's answer only applies if you're using CoreOS.

I've run into problems if the VirtualBox Extensions pack version differs from the version of VirtualBox. Also, install the Vagrant VirtualBox guest plugin:

vagrant plugin install vagrant-vbguest

And make sure to update the plugin when you update Virtualbox and the extension pack:

vagrant plugin update vagrant-vbguest
