Windows 10 guest using high cpu loads on linux … |VMware Communities

I have a Windows 10 guest running on a debian host. Running the guest frequently and quickly brings my HOST CPU to 100°C. Usually starting with Windows 10 startup process. CPU load is at 100% for around 5 minutes after loading Windows and chills to 5% if no activity is carried out. Temperature then drops to 60°C to 80°C while constantly cooling with high fan activity, rising and falling to 100°C from time to time (depending on current fan activity) Starting any program like the windows updater brings the machine back to constant 100°C.

 

While at 100°C, dmesg also shows alerts for all cores:

 

[ 8770.780647] CPU0: Package temperature above threshold, cpu clock throttled (total events = 60231)

 

The laptop is 2 Months old and running properly with all multithreaded programs on the bare host system. Temperature without VMs started is around 50°C for high loads and 40°C for idle. It has latest firmware installed and no dmesg errors appear on usage without VM.

 

I wanted to share this experience and ask for any recommendations for VMWare setup. Could be due to the Kernel from backports or an old Vmware Tools. In this state, VMware Workstation is laggy and barely unusable.

 

Settings:

The host is a dell precision 5530 laptop having 12 Threads available (i7-8850H). I assigned 1 CPU and 1 Thread in processor settings. The Guest gets 8GB of the available 32GB. The VM is running at 4K directly from an SSD. Graphics Memory is at 2GB, 3D enabled but running on integrated intel graphics.

 

Software:

VMware® Workstation 15 Pro Version 15.0.4 build-12990004

VMware Tools for Windows Version 10.3.2, build-9925305 (is this latest available?)

 

Host System

Host OS: Debian GNU/Linux 9.8 (stretch)

Kernel 4.19.0-0.bpo.4-amd64
