Quando tento ativar a interface de rede eth0 dentro de um contêiner LXC (Fedora 27), o comando mostra as seguintes mensagens de erro:
# ifup eth0
/etc/sysconfig/network-scripts/ifup-ipv6: line 56: /etc/sysconfig/network: No such file or directory
/etc/sysconfig/network-scripts/ifup-aliases: line 116: /etc/sysconfig/network: No such file or directory
No entanto, após o comando ser executado, a rede funciona bem, a configuração do ip4 está corretamente configurada.
# ip addr

O contêiner tem a janela de encaixe instalada, então não sei se isso pode estar relacionado ao problema.
O arquivo de configuração do contêiner ( /etc/pve/lxc/110.conf ) contém:

ATUALIZADO : criei novos contêineres com diferentes sistemas operacionais (Ubuntu e CentOS) e esse problema não acontece.
