OpenStack计算节点nove启动报错_modules with known eventlet monkey patching issues

OpenStack计算节点nove启动时提示如下错误：

[root@c2 ~]# systemctl restart openstack-nova-compute.service
Job for openstack-nova-compute.service failed because the control process exited with error code.
See "systemctl status openstack-nova-compute.service" and "journalctl -xeu openstack-nova-compute.service" for details.

查看日志，错误信息如下：

[root@c2 nova]# tail /var/log/messages

从中可以看到提示“Compute driver option required, but not specified”

在/etc/nova/nova.conf配置文件中可以找到compute driver选项被注释掉了，将注释符号删除，然后重启openstack-nova-compute.service即可，如下所示：

[root@c1 ~]# vim /etc/nova/nova.conf
……此处省略文件原有内容……
compute_driver=libvirt.LibvirtDriver

[root@c1 ~]# systemctl restart libvirtd.service openstack-nova-compute.service
[root@c1 ~]# systemctl status openstack-nova-compute.service
