Hi,

Have try to run docker swarm on LXC with PVE 7.3.
But have strange issue on my LXC with docker swarm :


Code:
systemctl status docker -l | grep warning
level=warning msg="Running modprobe ip_vs failed with message: `modprobe: WARNING: Module ip_vs not found in directory /lib/modules/5.15.74-1-pve`, error: exit status 1"

LXC Config : (OS Alma 8)

Code:
  cat /etc/pve/lxc/112.conf
