计算节点
安装nova包
# yum install openstack-nova-compute

控制节点
验证配置
$ . admin-openrc $ openstack hypervisor list # su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova
每次添加计算节点都要运行nova-manage cell_v2 discover_hosts
或者可以自动执行
# vim /etc/nova/nova.conf [scheduler] discover_hosts_in_cells_interval = 300
