我使用SELECT * FROM tTable
（版本1.2.12）创建1个控制器节点（主机名：HCP2-CTL-NODE-1），3个计算节点（HCP2-CPT-NODE-1,2,3），这些节点的操作系统是Centos7
然后我按照Openstack Newton Installation Doc for Red Hat Enterprise Linux 7 and CentOS 7在这4个节点上部署openstack
但是，当我想以上面的doc显示的方式启动实例时，它总是使用命令
openstack server show provider-instance0＆＃39;返回故障＆＃39;实例3fcd26fb-da04-412b-9970-65901354292b的构建中止：在主机上断开与管理程序的连接：HCP2-CPT-NODE-2＆＃39;
然后我读了日志
/var/log/nova/nova-compute.log'在主机HCP2-CPT-NODE-2上，
如下：
tTable此外，当我在3个计算节点上打印用户组时，它会打印：
virsh命令＆＃34; id nova＆＃34;打印：
