When I create a Rocky Linux 8.4 VM under ESXi 6.5, the VM continuously shows 100% CPU usage of any/all allocated cores in the VM console, although the OS shows minimal CPU usage. When I install CentOS 8.4, CPU usage in the VM console approximately matches the OS. Any suggestions? I’ve set the OS type to CentOS Linux 7 (64-bit) or RHEL 7 (64-bit). open-vm-tools is installed, and the machine is a Dell R610 with two X5675 CPUs. Please let me know if any other details are useful, thanks.
@SteveShockley, welcome to the Rocky Linux Forums.
- How many vCPUs did you allocate to your VM?
- How many CPUs total are on the physical host?
- How many vCPUs have you already allocated?
I saw this problem with VMware ESXi in a professional environment where there was a problem with over-subscription of CPUs and it was not obvious. That could be the problem in this case for you as well.
