I have the following setup:
Fully updated, freshly installed Windows 10 64bit on Lenovo W550s laptop. It is running VirtualBox version 5.2.18 r124319 with extension pack.
Fully updated, freshly installed Windows 10 64bit guest VM on 100GB dynamic disk. It has VirtualBox guest additions installed.
While the VM guest sits idle consuming only 2% CPU, but the host sees 30% consumed by vbox. Please see screenshot below:
So how can I go about diagnosing this, and what would be recommended fixes to try?
FWIW, It remains like this constantly. It is not just a momentary peak but a continuous problem.
