我使用 conjure-up 在 kvm 虚拟机上成功安装了 openstack nova-lxd。
VM 关闭后；当我启动 VM 时，openstack 没有启动。lxc 列表显示一个实例处于“正在运行”状态，而所有其他实例处于“已停止”状态。
我如何启动其他实例？
答案1
我也遇到了同样的问题。我在服务器上安装了全新的 Ubuntu 16.04，更新了所有软件包，然后我安装的唯一东西是 conjure-up，并用它来安装 lxc openstack。lxc list显示所有实例都已启动并正在运行，我可以登录到 openstack 仪表板，这很棒。然后我重新启动...现在lxc list显示除一个实例外，其他所有实例均未运行。@gangstaluv 回答您在我的环境中的问题：

您可以运行 lxc start 来重新启动它们。
当我尝试这样做时，出现一个错误，这可能解释了为什么事情没有自行恢复：
$ lxc start juju-ec5bf1-0
error: Missing parent 'conjureup0' for nic 'eth1'
Try `lxc info --show-log juju-ec5bf1-0` for more info
我不确定该怎么做。我还能检查些什么吗？我重新安装了 Ubuntu 和 conjure-up，以防我做错了什么，但每次它都能正常工作，直到重新启动，然后它又会处于这种状态。
编辑 1：我没有想到要添加它lxc info所说的要看的内容，现在就添加它。

编辑-2：我刚刚修好了我自己的！
经过大量研究我发现了命令lxc profile show
$ lxc profile show juju-conjure-up-openstack-novalxd-561

从输出中lxc info --show-log juju-ec5bf1-0我推测 juju（或其他组件）以某种方式看到了我的其他网卡（如果我没看错的话，我是在真实硬件上运行它，而不是在虚拟机上运行 Mirto Busico），并且正在寻找一个不存在的名为 conjureup0 的桥接器。我怀疑某个地方有错误，这就是为什么没有创建它。我想我可以做两件事之一来解决这个问题。1) 创建缺失的桥接器 2) 从配置文件中删除 eth1 设备。我选择了后者。
$ lxc profile device remove juju-conjure-up-openstack-novalxd-561 eth1
重新启动后，现在lxc list显示我的所有实例均按预期启动并运行，并且我的仪表板再次正常工作。
答案2
@gangstaluv：3 月份重新尝试从头开始安装，结果 conjureup0 在重启后仍然可用。
重启后，所有 lxd 容器都已启动并运行，但 rabbitmq-server 出现错误（为此，我将打开另一个线程）
答案3
我以前也遇到过这种问题，很可能是网络设置的问题。默认情况下，首次部署 conjure-up openstack 时 MTU 大小的值应为 1500。我的解决方案是在 lxc 配置文件配置中更改 MTU 大小。您也可以尝试这样做。
