我在多节点OpenStack（版本Juno）上设置nova-docker（docker hypervisor）有问题，我的操作系统是Ubuntu 14.04我跟着：https://wiki.openstack.org/wiki/Docker，当我通过仪表板或nova启动创建容器vm时，我在nova-收到错误compute.log

    本周有一个从1.6.2到1.7.0的docker更新 . 这个更新版本显然不支持1.14以下的任何版本的api . nova-docker驱动程序使用1.13 api . 目前解决方案是降级到docker 1.6.2（apt-get purge lxc-docker-1.7.0 && apt-get install lxc-docker-1.6.2） . 希望nova docker驱动程序将在不久的将来更新以支持更新版本的API .

    更新：问题似乎是novadocker驱动程序传递默认的VolumesFrom值“”（空字符串），当更新版本的docker希望它为空值时 . 我目前正试图弄清楚这是否应该被视为docker或novadocker驱动程序中的错误 .
