This is intentionally disabled upstream because xtables isn't compatible
with PREEMPT_RT.

Oh, I didn't know, I used it since 6.12 and just noticed that in newer
ones it's unavailable and it breaks default libvirt network

Should I report it to libvirt package ? With current setup of both,
switching to RT without changing libvirt config will just make default
network stop working

I'm reassigning this to libvirt.  No need to open another report.
