故障处理¶
问题1：物理机发生重启，虚拟机随之启动，出现 ERROR 状态¶
问题现象¶
Nova 配置文件中配置了 resume_guests_state_on_host_boot = true 当物理机重启时，虚拟机能自动随之启动；但物理机重启时，虚拟机启动有时会报 ERROR 状态。
处理过程¶
- 根据错误现象看，虚拟机启动的时候可能磁盘没有初始化完成或者 openstack-openvswitch-agent 未初始化完成，导致虚拟机启动的时候无法拿到磁盘或者 Port，从而启动失败。
- 分析原因，怀疑是 nova-compute 服务先于 cinder-volume 和 openstack-openvswitch-agent 服务启动造成的。
- 在 nova-compute 的 service 文件中的 after 选项增加 neutron-openvswitch-agent.service 和 openstack-cinder-volume.service，确保 nova-compute 服务在 neutron 和 cinder 服务之后启动。
# cat /etc/systemd/system/multi-user.target.wants/openstack-nova-compute.service
After=syslog.target network.target libvirtd.service neutron-openvswitch-agent.service openstack-cinder-volume.service
- 多次重启计算节点，虚拟机均可以随物理机正常启动。
问题原因¶
nova-compute 服务的启动依赖存在问题，修改依赖后解决。
问题2：计算节点多次自动重启，虚拟机需要做迁移¶
问题现象¶
马驹桥 Bss10 省测试集群，zabbix 检测到 10e129e168e154 物理节点多次自动重启，为不影响上面虚拟机的使用，需对虚拟机进行迁移。
处理过程¶
1.将 74 机器（原来的备机）从 dell_ag_backup 主机聚合移除，加入到 dell_ag_001 主机聚合。
# openstack aggregate remove host dell_ag_backup 10e129e168e74
# openstack aggregate add host dell_ag_001 10e129e168e74
2.将 154 的两台用户虚拟机迁移到 74 机器上。（虚拟机后端是共享存储）
# openstack server migrate cb064d0d-082b-4a80-acf9-6782030461b7 --live 10e129e168e74
# openstack server migrate 363b0da3-cfc4-4e78-9675-7a0784c9011c --live 10e129e168e74
3.将 154 的 volume 改到 74 机器上（这个脚本需要根据实际情况进行修改）。
# python volume_migrate.py
volume_migrate.py 具体内容如下：
import MySQLdb
host = 'mariadb.cty.os'
user = 'cinder'
passwd = 'xxxxxx' #需要 Cinder 数据库的密码
db = 'cinder'
port = 10024
old_host = '10e129e168e154'
new_host = '10e129e168e74'
try:
conn = MySQLdb.connect(host=host, user=user, passwd=passwd, db=db, port=port)
cur = conn.cursor()
cur.execute('select id from volumes where status!="deleted" and host="%s@ceph#RBD"' % old_host)
ids = cur.fetchall()
for id in ids:
cur.execute('update volumes set host="%s@ceph#RBD" where id="%s"' % (new_host, id[0]))
conn.commit()
cur.close()
conn.close()
except MySQLdb.Error, e:
print 'Mysql Error %d: %s' % (e.args[0], e.args[1])
4.将 154 从 dell_001 可用域移除，加入到 dell_ag_error 这个可用域。
# openstack aggregate remove host dell_ag_001 10e129e168e154
# openstack aggregate add host dell_ag_error 10e129e168e154
问题原因¶
初步判断为内核崩溃，导致物理机反复重启。
问题3：执行 nova rebuild 失败¶
问题现象¶
马驹桥 Bss 10 省测试集群，执行 nova rebuild 失败，compute 日志返回 Gateway Time-out(HTTP 504) 报错。
处理过程¶
1.执行 rebuild 命令。
# nova rebuild e7abbade-5e85-479f-a4c3-c02777881665 1f8c96a6-d143-409e-b446-095b1008b724
2.执行命令以后报错，查看虚拟机相关日志。
# cat /var/log/nova/nova-compute.log
2018-07-31 17:51:20.041 164773 ERROR nova.compute.resource_tracker [req-09082be7-7bb2-49db-b267-8746ebd2871d 8a974b0ae27f40ee87a92916f909360d c0f1fa6073be435491e4309ce0be959b - default default] [instance: e7abbade-5e85-479f-a4c3-c02777881665] Failed to clean allocation of evacuated instance on the destination node 020c4961-d2a1-49ec-b8d1-d15685ffadd9: ClientException: Gateway Time-out (HTTP 504)

3.根据报错内容 Gateway Time-out (HTTP 504) os-vol-host-attr:host”: “10e129e168e243@ceph#RBD 发现虚拟机的 volume 是由 10e129e168e243 节点管理的，查看 10e129e168e243 的服务信息。
# cinder service-list |grep 10e129e168e243
| cinder-backup | 10e129e168e243 | nova | disabled | down | 2018-07-21T02:38:15.000000 | - |
| cinder-volume | 10e129e168e243@ceph | nova | disabled | down | 2018-07-21T02:38:30.000000 | - |
发现 cinder-volume 为 down 的状态，因为之前 10e129e168e243 节点发生故障，机器已经下线。
4.登录数据库把原来 10e129e168e243 管理的 volume 改为可用的 cinder-volume 节点。
# update cinder.volumes set host="10e129e168e226@ceph#RBD" where host="10e129e168e243@ceph#RBD" and deleted=0;
5.修改完成以后，再次执行 rebuild 操作成功。
问题原因¶
计算节点下线，cinder-volume 服务 down，重装过程中会 detach 卷，无法管理 volume，导致重装失败。后续会有详细的物理机下线流程，解决这种操作带来的问题。
问题4：虚机被 OOM 后，启动以后，再 reboot 时，虚机报错¶
问题现象¶
物理机超配内存，导致用户虚机 OOM，启动用户虚机，虚机没法获取 IP，再次 reboot 虚机，结果虚机 ERROR。显示虚机的状态为：
# nova list --all |grep b323cc34-0355-43a6-992e-ae8d61095128
| b323cc34-0355-43a6-992e-ae8d61095128 | 192e168e3e57 | cbe062d323484a99b4ba5d28afeb698d | ERROR | - | NOSTATE | shanxi-net=192.168.3.57

在宿主机上通过 virsh list –all 查不到虚机
处理过程¶
1.查看虚机所在宿主机的 compute 的日志。
2018-09-27 15:11:31.481 181303 ERROR nova.virt.libvirt.guest [req-93b1f7e7-8713-4e68-951f-57aba0bbaf74 435320d9640446a1b3dd5aee4335b171 5e2214ea913a49babd5a4aab26e56ff8 - default default] Error launching a defined domain with XML: <domain type='kvm'>
可以看到虚机启动的时候，XML部分有报错。
2.因为虚机被 OOM，查看宿主机的 messages 日志，可以看到 OVS 的相关进程被 Kill 掉。

3.从日志中可以看出，虚机启动失败是因为 OVS 进程服务异常，导致虚机的 tap 设备丢失，进而导致虚机的 XML报错。
- 首先重启 OVS 进程，使 OVS 进程恢复正常。
- 虚机状态 ERROR，先把虚机的状态恢复成 ACTIVE 状态。
# nova reset-state --active b323cc34-0355-43a6-992e-ae8d61095128
4.通过 XML 恢复虚机的电源状态，首先将一个正常的虚机的 XML 文件拷贝一份为 test.xml，将 XML 文件中这三处的 uuid 修改为要恢复虚机的 uuid。
<domain type='kvm'>
<name>instance-b323cc34-0355-43a6-992e-ae8d61095128</name> #第一处
<uuid>b323cc34-0355-43a6-992e-ae8d61095128</uuid> #第二处
<metadata>
<sysinfo type='smbios'>
<system>
<entry name='manufacturer'>RDO</entry>
<entry name='product'>OpenStack Compute</entry>
<entry name='version'>17.0.3-1.el7.centos</entry>
<entry name='serial'>83ab3243-86bd-4a0e-a96a-acf59cc4620c</entry>
<entry name='uuid'>b323cc34-0355-43a6-992e-ae8d61095128</entry> #第三处
<entry name='family'>Virtual Machine</entry>
</system>
</sysinfo>
5.通过 virsh define test.xml 定义新的虚机。
- nova start b323cc34-0355-43a6-992e-ae8d61095128 启动虚机，最终虚机恢复。.。
问题原因¶
宿主机内存超配，导致虚机被 OOM，在虚机启动过程中，导致内存不够，将 OpenStack 的 OVS 进程杀死，导致虚机重启失败。因为虚机是使用的 CEPH 后端，所以数据不会丢失，进而可以使用 XML 重新恢复。
物理机修好以后启动，虚机手动启动报错¶
问题现象¶
物理机修好以后，进行虚机的启动，但是执行虚机启动命令以后，等下虚机状态还是 SHUTOFF。 通过命令查看虚机的错误信息如下：
# nova instance-action 24e713b9-2921-4cae-9733-d6ed957365d6 req-258d0d75-1575-4dcb-b5b8-01889627fcfa
处理过程¶
- 根据报错，查看计算节点，计算节点的服务没问题。
- 根据错误信息，好像是域名解析的问题，查看计算节点的 /etc/resolv.conf 文件，发现为空。
- 添加正确的 DNS 地址。
- 重启 nova-compute 进程（这步是必须的，重启才会加载新的 DNS 地址）。
# systemctl restart openstack-nova-compute
- 最后启动虚机，检查虚机正常启动
问题原因¶
物理机重启，有可能会导致 /etc/resolv.conf 此文件里面的地址被覆盖或者重写，导致 DNS 没办法正常解析。后续可以考虑将 /etc/resolv.conf 文件加锁，保证地址的正确性。
问题6：虚拟机 rebuild 失败¶
问题现象¶
虚拟机开机后，vnc 没有连接上，检查 vnc 服务没问题，定位问题在虚拟机，rebuild 虚拟机，执行命令后发现状态是 error 的。
处理过程¶
- 查看日志发现虚拟机没有 stop 成功。
- 在虚拟机所在的 host 上查看 nova-compute 的日志，没有 error。
- 查看 libvirt 的日志，发现 error：can not acquire state change lock，说明是 libvirt 死锁，重启 libvirt 服务后问题解决。
cat /var/log/libvert/libvertd.log
2019-03-06 01:15:18.437+0000：2769：error ：qemuDomainObjBeginJobInternal：5835 ： Timeout out during operation：cannot a
问题原因¶
libvirt 服务异常导致虚拟机关机不成功。
