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-compute.log中收到错误

任何人都可以帮助我吗？，谢谢大家！
答案 0 :(得分：0)
本周Docker的更新从1.6.2升级到1.7.0。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＆amp;＆amp; 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认为是docker或novadocker驱动程序中的错误。
