#查看是否支持cpu虚拟化
egrep -c '(vmx|svm)' /proc/cpuinfo# 如果为0 配置
vim /etc/nova/nova.conf
###
[libvirt]
# ...
virt_type = qemu
####启动服务
systemctl enable libvirtd.service openstack-nova-compute.service;systemctl start libvirtd.service openstack-nova-compute.service

#到控制节点controller
#验证
source admin-openrc.sh
openstack compute service list --service nova-compute#主机发现，每添加一台主机就要执行这个命令
su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova#配置以自动发现主机
vim /etc/nova/nova.conf###
[scheduler]
discover_hosts_in_cells_interval = 300  #每300秒执行以此上面那条主机发现命令
###

#3

在controller写重启脚本:

cd ~
vim restart-nova.sh###
#!/bin/bash
systemctl restart openstack-nova-api.service  openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service
####重启nova服务
bash restart-nova.sh
