And if so, between which host CPUs? Thanks for your response. No, I'm not performing any migration. The VM is static and only running Docker. The host CPU is an Intel N5105. It's not do= ing anything too intensive with VM CPU sitting at around 10% and the Host CPU sitting at around 5% (powersave governor set). The CPU governer was initially set to 'performance' which I've since change= d to 'powersave' using the intel_pstate driver but this hasn't improved the situation. There's quite a few people on the Proxmox forums (links below) running the = same CPU who have also encountered the same issue. Could there be an issue with = the kernel and this particular CPU? https://forum.proxmox.com/threads/vm-freezes-irregularly.111494/ https://forum.proxmox.com/threads/vms-freezing-randomly.113037/ https://forum.proxmox.com/threads/ubuntu-20-04-und-22-04-vms-bleiben-zuf%C3= %A4llig-h%C3%A4ngen-bsd-vms-nicht.113358/ https://forum.proxmox.com/threads/ubuntu-20-04-04-machine-freezes.112507/ https://forum.proxmox.com/threads/proxmox-vms-crashing-freezing-on-intel-n5= 105-cpu.113177/ https://forum.proxmox.com/threads/pfsense-vm-keeps-freezing-crashing.112439/ --=20 You may reply to this email to add a comment.
