After upgrading to PVE 8 and several CTs to Debian 12, I experience a loadavg discrepancy. The load averages shown in the CTs are that of the host, divided by the number of CPU cores of the LXC container (per-core loadavg in Zabbix), instead of the load of the LXC guest itself. The commands uptime, top, and the contents of the /proc/loadavg are fine and showing the correct values. Debian 11 and earlier behave correctly, the Zabbix agent sends the correct values representing the actual guest load. The hosts are all using the lxcfs --enable-loadavg feature.
I'm not sure if the issue lies with Debian, the Debian template, LXC, LXCFS, a patch the Proxmox team applies to a component, or somewhere else, but I thought it's best to also ask here. PVE 8.0.x and 8.1.x behaves the same.
Please also see this on the Zabbix forums, detailing the problem a bit more: https://www.zabbix.com/forum/zabbix...debian-12-zabbix-reports-load-average-of-host
