[lxc-users] CRIU with lxc.network.type empty fails

[Dietmar Maurer]

I no get another error:

(00.000399) Error (proc_parse.c:826): SECCOMP_MODE_FILTER not currently
supported
(00.000401) Error (proc_parse.c:839): Error parsing proc status file

So I have to set:

lxc.seccomp =

which is bad, because 'umount -f' can be used to terminate lxcfs...

After that, I get:

This is a simple centos7 container - nothing running (onyl systemd).
Any idea whats wrong?
