我用devstack配置的openstack,用demo账户登录,按照官网文档里面的顺序那样配置了project, key pair等,之后想从我上传的ubuntu的镜像ubuntu12.04-desktop-amd64.img里面启动instance,不行,之后再试从自带的cisco镜像上传,还是显示no valid host was found,请问这是个什么情况,怎么能够解决?

Check /var/log/nova/nova-scheduler.log for reason. Generally speaking, you don't have enough memory, disk or suitable port(s) ('PortInUse: Port 1840a52b-0115-4e7c-920d-5e548e7d612d is still in use) to create your instance.

这种情况我遇到过很多,我觉得最可能就是1,网络配置不正确;2,内存不够。不过你还是查查日志文件吧。

查看日志 应该是compute节点没有配置好,重新配置nova-compute

先检查 compute 的日志,试试将虚拟机类型改成 qemu
