We are still investigating the high CPU temperatures we're seeing on some of our XCP-ng hosts.
Worth noting: the affected hosts are only running two VMs:
A small XOA appliance (2 vCPU, 2 GiB RAM)
A single Ubuntu VM acting as an application server (10 vCPU, 24 GiB RAM), running just one business application.
Here is the output from lscpu on one of these systems:

We would appreciate any feedback regarding recommended CPU configurations for this type of setup under XCP-ng. Could the current virtual CPU allocation be contributing to thermal issues?
Thanks in advance!
