Fellows, please help me out. Proxmox CPU C-states become this misery when Unraid is running. Stock, fresh 7.0.1 install !! No pci passthrough, just the usbdrive and a virtual disk just to be able to start the array.

 

and with unraid stopped with just OPNsense vm running. (OPNsense does nothing bad to the c-states. It's as if it's not running)

 

and oh well, fresh install of truenas VM just for comparison.

 

 

At least it's not zero. Any suggestions ?? Anyone ??

 

Thank you

I've had the same issue for couple of days. But mine instance of proxmox + unraid vm have worked fine for months and suddenly c-states wanished. Of course power consumption went up as well. No idea what channged.

If you find out anything, let me know please. 

What kernel version do you have? I downgraded to 6.8.12-7-pve and C7 came back

While unraid VM is running ?? I have a Nvidia gpu on the system. The max I will get will always be C3 (with nvidia drivers installed) but I lose any C state when I start the unraid VM. Is it the same for you ?

EDIT: This image pretty much sums it all. Unraid does not "idle", ever.. I tried your kernel. Same result.
