libvirt by default has cgroup controllers of ["cpu", "devices", "memory", "blkio", "cpuacct"] as shown in qemu.conf. I want to add one more controller of net_cls. I tried to modify the config file to make the update.
cgroup_controllers = ["cpu", "devices", "memory", "blkio", "cpuacct", "net_cls"]
I restarted cgroup and libvirt service but the new controller didn't show up. How to add net_cls to libvirt group in cgroup?
