lxc/kvm 容器启动失败

我已经准备好 MAAS+Juju 设置，并成功在特定机器上部署了一些 openstack charms。然后，我读到将这些 openstack charms 放在自己的容器中是安全且良好的做法。我尝试了

juju deploy --to lxc:14  --repository=/opt/charms local:trusty/keystone

魅力已成功添加，但juju stat显示

  "14":
    agent-state: started
    agent-version: 1.20.10
    dns-name: slot13.maas
    instance-id: /MAAS/api/1.0/nodes/node-9cf5e120-5625-11e4-b22e-a41f72f16283/
    series: trusty
    containers:
      14/kvm/0:
        agent-state-info: 'kvm container creation failed: exit status 1'
        instance-id: pending
        series: trusty
      14/lxc/0:
        agent-state-info: container failed to start
        instance-id: pending
        series: trusty
    hardware: arch=amd64 cpu-cores=4 mem=32768M

我尝试使用 kvm 容器，结果相同（您甚至可以看到上面的错误。对于 KVM 容器，我确实在 BIOS 中启用了虚拟化技术）。

juju debug-log节目

目标节点上的 /var/log/juju 中没有 service/charm(keystone) 特定日志。我希望放入容器中的所有服务都出现了这种情况，而不仅仅是 keystone 或 openstack 服务。

笔记lxc-create：由于一些代理问题，我在目标节点上遇到了问题，我认为我的早期帖子解决了这个问题。但我在这个问题中描述的问题并没有消失。

编辑：我找到了容器故障日志，并将其粘贴在这里-

第一个错误rootfs specified but no console found at '/usr/lib/x86_64-linux-gnu/lxc/dev/console'确实是正确的，因为没有路径'/usr/lib/x86_64-linux-gnu/lxc/dev/console'。目录结构以 '/usr/lib/x86_64-linux-gnu/lxc/' 结尾

我遇到了类似的错误。不完全相同，但解决方案是删除 lxcs。

rm -rf /var/lib/lxc/offending-container-xx
rm -rf /var/lib/juju/containers/offending-container-xx

如果有人遇到类似的错误，希望这会有所帮助。
