high cpu

I have noticed a few times when logging into my proxmox server the cpu spikes like crazy for no reason and doesn't stop when I disconnect and only stops after a reboot. I only have and unraid vm on the server(for some reason the unraid shows a lil bump in cpu usage but not even close to the cpu...

Hi Everyone, I have a 2 x 2673 v4 Xeons and proxmox is has been running generally fine ( with a few exceptions). Anyhow, it came to my attention is that there a a specific CPU core that is always near 100%. out of 80 vCPUs this one is persistent. core #4 any idea how can I find which process...
