问题
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

Please do the following :
- Set $enable_serial_logging=false in config.rb
- vagrant destroy
- vagrant up
- Observe three VBoxHeadless processes under 3% CPU
And check these links:

Make sure vbguest plugin updated
vagrant plugin update vagrant-vbguest
If it wasn't installed already, you can install it with
vagrant plugin install vagrant-vbguest
Now, disable the sound In VirtualBox window:
- click on the machine you are using
- Click settings
- Go to: Audio Tab
- Uncheck both "Enable Audio Output" and "Enable Audio Input"
This combination should stop the horrible CPU craziness in Mojave-Virtualbox.
if you wish to take one step forward. you may reduce the general CPU consumption:
- Click on the Machine --> Settings --> System --> Processor
- Reduce the Execution Cap. this limits the % of the host CPU, that the guest CPU can use. (default, is 100% - no limit).
