centos7.3内核安装M版本openstack

1.升级内核

因为服务器不支持centos7.2版本，centos7.2安装后，服务器网卡不能正常使用，但是服务器可以使用支持centos7.3版本。采用升级7.2内核版本至7.3，使用7.3内核来驱动服务器网卡。升级完成后，网卡启动。

升级内核命令，只升级内核版本。

yum install kernel-3.10.0-514.el7.x86_64.rpm

升级完内核版本后，重启服务器。在后续的安装过程中yum使用centos7.2版本源。使用centos7.2做yum源，执行yum upgrade 报错

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

##取消更新

2.创建云主机报错

待安装完成M版openstack，创建云主机报错

3.修改nova参数

在控制节点修改nova配置文件，添加allow_duplicate_networks=False配置
参考文档：https://bugzilla.redhat.com/show_bug.cgi?id=1416249

Here's the result of egrep -v '^(#|$)' /etc/nova/nova.conf
[neutron]
project_name=service
allow_duplicate_networks=False
##只修改了这一句代码   (BoolOpt) Allow an instance to have multiple vNICs attached to the same Neutron network.
##允许一个实例有多个VNICs附着在同一个中子网络上
extension_sync_interval=600
auth_url=http://10.20.0.105:35357/v3
user_domain_name=Default
timeout=30
project_domain_name=Default
url=http://172.17.0.18:9696
ovs_bridge=br-int
region_name=RegionOne
username=neutron

重启所有服务，生效配置
openstack-service restart
