After installing lxc 4.0.11, no container starts

[Saint Michael]

lxc-start: demo: conf.c: lxc_setup_rootfs_prepare_root: 3946 Failed to
setup rootf
lxc-attach --version
4.0.11
the container is not inherited, it was created a few minutes ago:

lxc.include = /share/lxc/config/common.conf
lxc.arch = x86_64

Container specific configuration

lxc.rootfs.path = dir:/var/lib/lxc/demo/rootfs
lxc.uts.name = demo

Network configuration

lxc.net.0.type = veth
lxc.net.0.link = br0
lxc.net.0.flags = up
lxc.net.0.hwaddr = 00:16:3e:8f:66:46

ls /var/lib/lxc/demo -hls
total 8.0K
4.0K -rw-r----- 1 root root 737 Oct 23 16:35 config
0 drwxr-xr-x 18 root root 239 Oct 23 16:35 rootfs

Selinux is off
getenforce
Disabled

This is Centos 8

what is keeping any containers at all to start?

Hey, can you show me the full trace log, please, i.e.

lxc-start <container> -l trace -o <file.log>

and then give me the contents of file.log, please?

Thanks!
Christian

I decided to erase the box and install an Operating System with good
support for containers.
But the developers should offer a *.rpm for Centos 8. One that would
offer the latest version available.
It turns out to be impossible to install LXC 4.XX on Centos 8 from
sources, which restricts the technology to Debian derivatives.
Thanks to all for your help.
