nova 计算节点启动异常

环境：C7.1+L版
启动计算节点nova：
[root@linux-node2 ~]# systemctl enable libvirtd openstack-nova-compute
[root@linux-node2 nova]# systemctl start libvirtd openstack-nova-compute

查看启动状态：
[root@linux-node2 ~]# systemctl status libvirtd

验证nova是否注册成功：
#没注册过来
[root@linux-node1 ~]# source admin-openrc.sh
[root@linux-node1 ~]# openstack host list

nova的配置不多，查看下关于libvirt的相关配置

这个配置文件检测下，你在L 版中找到对应的信息
/etc/nova/nova.conf:
# COMPUTE
libvirt_type=kvm
compute_driver=libvirt.LibvirtDriver
instance_name_template=instance-%08x
api_paste_config=/etc/nova/api-paste.ini

还有
compute_driver=libvirt.LibvirtDriver  
还是
compute_driver=nova.virt.libvirt.LibvirtDriver

这是原配置信息：

这是原配置信息：
[root@linux-node2 ~]# grep -n '^[a-Z]' /etc/nova/nova.conf
196:my_ip=10.0.0.3

2311:virt_type=kvm
换成qemu
2311:virt_type= qemu

然后重启下服务
[mw_shl_code=bash,true]service nova-compute restart[/mw_shl_code]
这是Ubuntu的，找到centos对应的服务

只需要改这个参数吗，其他的需要改吗
[root@linux-node2 ~]# grep virt_type /etc/nova/nova.conf
virt_type=qemu
#libvirt_type=kvm
# Override the default libvirt URI (which is dependent on virt_type) (string
# is dependent on virt_type. (valid options are: sd, xvd, uvd, vd) (string
# CPU model; to "none" to not set any CPU model. If virt_type="kvm|qemu", it
# virt_type="kvm|qemu" (string value)
[root@linux-node2 ~]# systemctl restart libvirtd               
[root@linux-node2 ~]# systemctl restart openstack-nova-compute
[root@linux-node2 ~]# systemctl status openstack-nova-compute
