类似于以下报错，通常都是nova用户ssh无密码登录设置不对Command: ssh 192.168.18.43 mkdir -p /var/lib/nova/instances/eac0e362-352f-45ad-b503-d28e588691beExit code: 255Stdout: ''Stderr: 'Host key verification failed.\r\n'. Setting instance vm_state to ERROR解决方法：一、计算节点先修改系统用户nova，允许su成nova用户。 & & & & vim /etc/passwd & & & & nova:x:109:116::/var/lib/nova:/bin/flase改成 & & & & nova:x:109:116::/var/lib/nova:/bin/sh二、通过nova系统用户来用ssh-keygen创建公钥 & & & & su - nova & & & & ssh-keygen -t rsa输入后，会提示创建.ssh/id_rsa、id_rsa.pub的文件，其中第一个为密钥，第二个为公钥。过程中会要求输入密码，为了ssh访问过程无须密码，可以直接回车。三、查看钥匙 & & & & ls /var/lib/nova/.ssh/ & & & & ###可以发现 ssh目录下的两枚钥匙。 & & & & id_rsa &id_rsa.pub & & & & ###修改authorized_keys权限为600 & & & & mv &id_rsa.pub authorized_keys & & & & chmod 600 authorized_keys最后把id_rsa，authorized_keys 拷贝到其它计算节点，我这里是：192.168.18.43 & & & & scp id_rsa.pub authorized_keys 192.168.18.43:/var/lib/nova/.ssh/注意：记得修改权限 & & & & chown root.root /var/lib/nova/.ssh/ & & & & chmod 600 /var/lib/nova/.ssh/authorized_keys & & & & chmod 600 /var/lib/nova/.ssh/id_rsa修改之后的权限应该是： & & & & -rw------- &1 nova nova &400 May &6 13:14 authorized_keys & & & & -rw------- &1 nova nova 1679 May &6 13:17 id_rsa四、测试 & & & & su - nova & & & & ssh 192.168.18.43可以登录且无密码的话，这个时候你再测试nova resize，应该就没问题了。本文出自 “” 博客，请务必保留此出处

Mitaka版之neutron
Openstack& Mitaka版之neutron& vxlan安装
& 版本 0.50& 时间
（一）&&& 引子
Openstack众多组件中，网络组件neutron是核心组件之一，也是不同版本中变化较大的一个组件。最开始安装Openstack& Juno版时，就卡在neutron安装上，openvswitch好像比较高深，安装出错时，不知道如何调试。上官网查资料时，发现新版Liberty的neutron组件默认基于linuxbridge而不是openvswitch，neutron安装要容易得多，而且网络效率更高，于是果断放弃头疼的Juno版，越过kilo版，重新安装liberty版。用2-3周时间基本完成了liberty版的openstack各组件安装，刚想欣赏一下战果，很快新的mitaka版又出来了，mitaka版相对于liberty版变化不太大，网络组件neutron也无大的变化，轻松升级。只用了几天时间，openstack各组件都从liberty升级到mitaka，较为顺利。
（二）&&& 安装环境
& 之前安装Juno版时，因为控制器rq940只有2块万兆网卡，Juno版官方安装指南要求neutron组件的网络节点应有3块以上网卡，因此选了较为空闲且有3块网卡的rd640c作网络节点。Liberty版不要求安装专门的网络节点，直接在控制节点上安装neutron核心组件即可，2块网卡即可满足要求。
&& 升级前，我先清除了各节点上的Juno版组件，全新安装自然无需如此。
清除libvirtd安装的vnet，以x3300为例：
[root@x3300 ~]# ip route

192.168.122.0/24 dev virbr0& proto kernel& scope link& src 192.168.122.1
[root@x3300 ~]# virsh net-destroy default

（三）升级内核至4.5
&Liberty版本基于linuxbridge实现的vxlan，需要内核为3.15以上，而centos 7.2的内核是3.10系列，因此需要单独升级内核。
安装新内核
rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
yum install http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpm
yum --enablerepo=elrepo-kernel install kernel-ml
使用4.5内核
查看引导选项
More /boot/grub2/grub.cfg
设置4.5内核为默认引导项
[root@rd640c grub2]# grub2-set-default &CentOS Linux (4.5.0-1.el7.elrepo.x86_64) 7 (Core)&
确认设置成功：
[root@rd640c grub2]# grub2-editenv list
saved_entry=CentOS Linux (4.5.0-1.el7.elrepo.x86_64) 7 (Core)
rq940升级内核，重启，之后无法用ssh连上，只好到几百米远的机房查看。原来关机时死锁了，只能按电源冷启动了。其他服务器均重启顺利。
（三）&&& 数据库安装
首先删除之前Juno版本的neutron数据库。

（四）&&& 最简安装（运营商网络）
Neutron安装，按指南区分二种情况：运营商网络（provider network）及自服务网络（self-service network）。运营商网络最简单，运营在二层，支持flat及vlan，但无三层服务，租户无法自定义高级网络服务。而自服务网络，租户可实现路由、防火墙、负载均衡等高级网络服务。
首先安装控制器组件.

(六)vlan支持
开始最简单的flat模式容易成功，但切换成手册上的网络选项之二以支持vxlan时，却失败了。因为flat模式无法满足基本的业务需求，内网与外网的分离等，尝试让neutron支持vlan。
首先要进行物理网络的一点小调整，各节点对外网接口原来为vlan 600，模式是access，这次统一切换成trunk。
[root@rq940 ~]# brctl show
bridge name&&&& bridge id&&&&&&&&&&&&&& STP enabled&&&& interfaces
brq518b8ede-d8&&&&&&&&& c426e42&&&&&& no&&&&&&&&&&&&& eth0.615
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& tapcb20b460-87
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& tapddb8dc9a-72
brq52fe0a18-80&&&&&&&&& bc5b9096&&&&&& no&&&&&&&&&&&&& tapf609aa98-30
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& vxlan-79
brq-9d&&&&&&&&& 13454fc&&&&&& no&&&&&&&&&&&&& tapd83dabbb-50
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& vxlan-65
brqa8ebc050-04&&&&&&&&& 00000&&&&&& no
brqf0fb0256-d4&&&&&&&&& c426e42&&&&&& no&&&&&&&&&&&&& eth0
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& tap3fe1bcf6-9d
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& tap43db3598-47
控制节点上，eth0接外网，eth0.615是vlan 615.
依然没有成功，后来发现与设置无关，是系统的bug，yum upgrade即一切搞定。
（七） 支持vxlan
[root@rq940 ~]#& source demo-openrc.sh
首先创建用户网络private7
[root@rq940 ~]#& neutron net-create private7
Created a new network:
+-----------------------+--------------------------------------+
| Field&&&&&&&&&&&&&&&& | Value&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& |
+-----------------------+--------------------------------------+

| subnets&&&&&&&&&&&&&& |&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& |
| tenant_id&&&&&&&&&&&& | 4cb482ade6b9abed2964&&&& |
+-----------------------+--------------------------------------+
再创建private7的子网络。
[root@rq940 ~]# neutron subnet-create private7 172.16.7.0/24 --name private7 \
&&& --dns-nameserver 202.99.96.68 --gateway 172.16.7.1
Created a new subnet:
+-------------------+------------------------------------------------+

| subnetpool_id&&&& |&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& |
| tenant_id&&&&&&&& | 4cb482ade6b9abed2964&&&&&&&&&&&&&& |
+-------------------+------------------------------------------------+
创建供私有网络private7的路由器router7
[root@rq940 ~]# neutron router-create router7
Created a new router:
+-----------------------+--------------------------------------+
| Field&&&&&&&&&&&&&&&& | Value&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& |
+-----------------------+--------------------------------------+
| admin_state_up&&&&&&& | True&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& |
| external_gateway_info |&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& |

| status&&&&&&&&&&&&&&& | ACTIVE&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& |
| tenant_id&&&&&&&&&&&& | 4cb482ade6b9abed2964&&&& |
+-----------------------+--------------------------------------+
路由器router7加入连接private7的接口。
[root@rq940 ~]# neutron router-interface-add router7 private7
Added interface bf324ff0-61d9-4493-aa0d-e to router router7.
给router7设置默认对外网关。
[root@rq940 ~]# neutron router-gateway-set router7 public
Set gateway for router router7
[root@rq940 ~]# source admin-openrc.sh
查看网络名称空间

Ping不同router7的默认网关。在dashboard显示接口down掉了，且无法up。
使用dashboard重复以上操作，错误如故。
实例（mitaka改称云主机了）上添加网络接口均失败。
细心对照指南，认真纠正配置错误，未发现实质性错误，反复测试，均失败。
卡住了二天，实在找不出错误，忽然想到是不是系统问题呢。
在rq940上执行yum upgrade
Openstack部分仅neutron组件有更新，感觉有希望。

果然，不用作任何修改，网络都通了，支持vxlan成功。
添加安全组规则，放行icmp包及开放ssh端口。
