High CPU temp running VMs in QEMU

I can’t figure out what has changed, nothing in my VM configs have changed for months.

Idle in Garuda I am running around 45-50 Degrees C.

Start a VM and shortly I am up in the upper 80s and at times 90c. Stop the VM and I am back down. While I expect an increase, this obvisouly starts to set off BIOS temp warnings and CPU throttling.

With nothing running other than Windows 10 basic services and nvidia pass thru. Same issue on my Windows 11, nothing running but the OS and nvidia drivers basicly.

Again its been fine quiet sometime. AIO pump is working, CPU Fan per say is working. If I reboot to windows and use VM workstation I stay around 65 to 70.
Not sure whats changed in my Garuda setup to cause the increase in heat.

Any ideas would be great.

check if you vm’s are in performance mode. also there are lots of junk always running in windows 10 and 11 that eat cycles. could also have malware running in windows, many different factors up to and including intel’s “performance boost” is kicking in. intel and amd have been “boosting” their cpu’s into the 90’s as default behaviour for a while now.

Most likely not related to your issue, but this should be fixed with a garuda-update.

I wondered on that route as well. I have been waitong the next nvidia update to be released to see if it fixes my slow boot times. Was waiting on something newer than nvidia-dkms 545.29.02-2 → 545.29.06-1 to be released. I maybe better off just to update and wait with the 3 minute boot times. I will try that and see what happens. I just miss the instant on :wink: after I update.

Thank you,

Hi.
In my opinion, just for testing.

You can create a new vm with a fresh install win10 or 11. In this case you can find out that the problem is in the garuda system/vm or in your windows 10-11 systems.

Maybe just some win update messed up your windows system…

No luck either way, made a new VM, applied all updates.

Took a break for bit for some gaming, and new year. Ill get back to this in a few days.
