Hi, Idle OpenBSD VM constantly uses ~11% CPU. Linux and FreeBSD VMs with exactly the same configuration use ~1%. What I've tried so far: - removed all network adapters - shutdown all services in OpenBSD VM - changed Machine from default i440fx to q35 - changed CPU types - removed Display - all above in combinations
I've posted about this issue on Proxmox forum. https://forum.proxmox.com/threads/high-pve-cpu-usage-from-idle-vm.143550 It would be great if somebody could help me to resolve this. Thank you in advance. pveversion --verbose -------------------------------------------------- proxmox-ve: 8.1.0 (running kernel: 6.5.13-1-pve) pve-manager: 8.1.4 (running version:
