trove password

edit

Hello. I used fuel to deploy the openstack and installed trove according to the book "OpenStack Trove 1484212223".Then I download ubuntu-mysql image on the offical website http://tarballs.openstack.org/trove/images/ubuntu (http://tarballs.openstack.org/trove/i...) . But every time after creating a instance using trove, the state of that instance will become error after build. Plus i cannot ssh it for not knowing the password, but i can ping it using floating IP. My question is: whoever knows the password for the ubuntu-mysql image? Why the state is error? the log shows that “ Cannot find compute instance None for instance”

我用fuel9.0安装了openstack，然后按照官网和书 "OpenStack Trove 1484212223"安装了trove。使用了官网 http://tarballs.openstack.org/trove/images/ubuntu (http://tarballs.openstack.org/trove/i...) 上的ubuntu-mysql镜像。但是每次用trove创建完实例以后，他的状态都会从build变成error，日志返回 Cannot find compute instance None for instance 。而且我只能ping通他，却不能ssh连接，因为不知道密码。 我的问题是：1：官方镜像的密码是什么？ 2：镜像状态是error的问题应该怎么解决？
