检测是否支持虚拟化

#  egrep -c '(vmx|svm)' /proc/cpuinfo

无回显用qemu，有回显用kvm

[libvirt]
# ...
virt_type = qemu
cpu_mode=none

启动服务并设置开机启动

# systemctl enable libvirtd.service openstack-nova-compute.service

# systemctl start libvirtd.service openstack-nova-compute.service

验证

# openstack compute service list --service nova-compute

任一控制节点上
发现计算节点

# su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova

如果配置自动发现

[scheduler]
discover_hosts_in_cells_interval = 300

验证

查看服务

#  openstack compute service list

在Identity Service中列出API的endpoint，以验证与Identity服务的连接正常

#  openstack catalog list

查看镜像服务

#  openstack image list

验证cells and placement API 是否正常

# nova-status upgrade check

Neutron

安装软件包

# yum  -y install openstack-neutron openstack-neutron-ml2 openstack-neutron-openvswitch

创建软连接

# ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini 

启动服务

# systemctl start openvswitch 

# systemctl enable openvswitch 

创建网桥

# ovs-vsctl add-br br-int 

启动服务

# systemctl restart openstack-nova-compute 

# systemctl start neutron-openvswitch-agent 

# systemctl enable neutron-openvswitch-agent
