I've been using headless VB for quite a while (via vagrant) with no issues. Recently, I've had major issues with the kernel extensions preventing my mbpro from sleeping.

This issue seems to be related to the audio driver, this is what the console logs are showing:

Code: Select all

If I completely purge Virtualbox the issue clears up. I've upgraded to the latest version, but I'm still getting sleep related crashes and a system that refuses to sleep at all. In fact, my machine is completely unstable with VB installed if sleep ever tries to initiate.

I'd love some suggestions on solving this. Is it possible to just disable the audio kernel extension? Since I only run in headless mode, is it possible to disable all of the kernel extensions without major repercussions?

Thanks.

Maybe I should take another approach to asking this... is anyone currently using Virtualbox on a Macbook Pro with Yosemite and not experiencing this issue?

It would help if you mention the exact VirtualBox version you are using.

Also, while trying to put your system to sleep do you have VMs running or just having VirtualBox installed prevent your system from sleeping.

Basically, we need a lot more info.

Thanks for responding. I'm getting ready to format my machine as removing Virtualbox is no longer solving the issue (it did previously). So, I give up.

I upgraded to VirtualBox-5.0.0-101573-OSX
