1.首先查看全部服务是否已经启动
运行 # nova-manage service list
Binary Host Zone Status State Updated_At
nova-consoleauth mycontrollerinternal enabled :-) 2014-06-0602:44:41
nova-scheduler mycontrollerinternal enabled :-) 2014-06-0602:44:41
nova-conductor mycontrollerinternal enabled :-) 2014-06-0602:44:37
nova-cert mycontrollerinternal enabled :-) 2014-06-0602:44:41
nova-compute mycomputenode nova enabled :-) 2014-06-0602:44:34
假设你看见的是:
nova-compute mycomputenode nova enabled XXX 2014-06-0602:46:14
启动这个服务就能解决上述问题
/var/log/nova/compute.log 在这两个文件里都能够查看错误信息
/var/log/nova/scheduler.log
2.我也遇见过是由于openstack 里面创建的虚拟机个数已经超出了你的设置上限,能够尝试删除几个在创建。
