Eu tenho um contêiner LXC OS (CentOS 7) configurado via libvirt (CentOS 7): 

<domain type='lxc'>
  <name>lxc-test1.example.com</name>
  <uuid>5a715193-55ef-49d7-a4f6-ac5c27bce838</uuid>
  <memory unit='KiB'>2097152</memory>
  <currentMemory unit='KiB'>2097152</currentMemory>
  <vcpu placement='static'>4</vcpu>
  <os>
    <type arch='x86_64'>exe</type>
    <init>/sbin/init</init>
  </os>
  <features>
    <privnet/>
  </features>
  <clock offset='utc'/>
  <on_poweroff>destroy</on_poweroff>
  <on_reboot>restart</on_reboot>
  <on_crash>restart</on_crash>
  <devices>
    <emulator>/usr/libexec/libvirt_lxc</emulator>
    <filesystem type='mount' accessmode='passthrough'>
      <source dir='/var/lib/libvirt/filesystems/lxc-test1.example.com'/>
      <target dir='/'/>
    </filesystem>
    <interface type='bridge'>
      <mac address='00:16:3e:c3:6c:78'/>
      <source bridge='br_v123'/>
    </interface>
    <console type='pty'>
      <target type='lxc' port='0'/>
    </console>
  </devices>
</domain>

Quando o contêiner inicia, ele não configura sua rede apropriadamente conforme definido em seu local /etc/sysconfig/network-scripts/ifcfg-eth0 

TYPE=Ethernet
BOOTPROTO=none
DEFROUTE=yes
NAME=eth0
DEVICE=eth0
ONBOOT=yes
IPADDR=10.2.0.1
PREFIX=24
GATEWAY=10.2.0.254
DNS1=10.0.0.18
DNS2=10.0.0.19

No entanto, se eu ifdown eth0 && ifup eth0 dentro do contêiner obtiver a configuração desejada. 

# ip addr

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

       valid_lft forever preferred_lft forever

Como posso fazer o libvirt iniciar a rede do contêiner corretamente?
