文章

1. 介绍
2. 安装管理器（ovirt引擎）和管理程序（主机）
3. 其他设置
4. 基本操作-我们在这里

• 行政门户
• 虚拟机门户

status = unassigned or status = maintenance or status = installing or status = reboot or status = preparingformaintenance or status = pendingapproval or status = connecting or status = installingos or status = kdumping

创建虚拟机和模板

• 机架单元-服务器；
• 显示器-桌面；
• 3个塔-池中的服务器；
• 3个监视器-池中的桌面；
• 倒带（倒带）-无状态（计算机在关闭后将其状态重置为原始状态；所有更改都会回滚）；
• 橙色监视器中的三角形-要求的配置更改需要重新启动。

VM迁移（实时迁移）

存储迁移

重命名VM和磁盘

更新oVirt-Host（系统管理程序）

更新oVirt-Engine（经理）

1. 如果可能，请对计算机进行存档或快照，请确保上次计划的备份成功。
2. 我们检查并更新安装软件包：
   
   

   $ sudo engine-upgrade-check
   $ sudo update ovirt\*setup\*

3. 更新的主要部分由引擎设置程序执行。她将询问许多配置问题，然后停止ovirt-engine服务，下载并安装更新的软件包，创建档案并更新数据库，应用更新的配置，然后启动ovirt-engine服务。
   
   

   $ sudo engine-setup

   
   成功更新后，我们将收到以下消息：
   
   

   Execution of setup completed successfully

   
   
   引擎设置脚本的示例输出

   $ sudo engine-setup

             Setup needs to install or update the following packages:
             [updated] ovirt-engine-4.3.5.5-1.el7.noarch will be updated
   ...
             [update] ovirt-engine-wildfly-overlay-17.0.1-1.el7.noarch is an update
             Replying "No" will abort Setup. You can pass the option "--offline" to prevent installing or updating packages.
             Do you wish to update them now? (Yes, No) [Yes]:

             Setup can automatically configure the firewall on this system.
             Note: automatic configuration of the firewall may overwrite current settings.
             NOTICE: iptables is deprecated and will be removed in future releases
             Do you want Setup to configure the firewall? (Yes, No) [Yes]: 
   [ INFO  ] firewalld will be configured as firewall manager.
            
             --== DATABASE CONFIGURATION ==--
            
             The detected DWH database size is 439 MB.
             Setup can backup the existing database. The time and space required for the database backup depend on its size. This process takes time, and in some cases (for instance, when the size is few GBs) may take several hours to complete.
             If you choose to not back up the database, and Setup later fails for some reason, it will not be able to restore the database and all DWH data will be lost.
             Would you like to backup the existing database before upgrading it? (Yes, No) [Yes]: 
             Perform full vacuum on the oVirt engine history
             database ovirt_engine_history@localhost?
             This operation may take a while depending on this setup health and the
             configuration of the db vacuum process.
             See https://www.postgresql.org/docs/10/sql-vacuum.html

4. 我们更新了操作系统和其他软件包：
   

   $ sudo yum update

   
   如有必要（更新内核或其组件），我们将重启计算机。

导入虚拟机

1. 从VMware ESXi / VSPHERE导入VM可以在主机+上运行ESXi / VSPHERE的主机上进行身份验证
2. 从Libvirt导入KVM / Xen VM：用户向运行Libvirt的主机指定URL +身份验证
3. 从给定的路径导入KVM / Xen VM：用户指定VM配置和磁盘的nfs / posix路径
4. 导入从VMware导出的VM：用户指定ova文件的nfs / posix路径
5. 上载KVM / Xen VM：用户指定配置文件和磁盘
6. 从VMware导出的上载VM：用户指定ova文件
7. 从文件夹导入VM：用户指定包含KVM / Xen VM或从VMware导出的VM的文件夹的路径

从vCenter导入计算机

• 数据来源：VMware；
• 外部提供程序：在管理->提供程序中，您可以配置用于频繁操作的模板；
• vCenter：vCenter服务器的名称或地址；
• ESXi：我们将从哪个虚拟机管理程序接车；
• 数据中心：群集的完整路径；
• 集群：包含管理程序集群；
• 用户名/密码：用于连接vCenter的用户名和密码；
• 验证服务器的SSL证书：使用自签名证书时，您必须禁用其验证。

从KVM导入机器

$ sudo vim /etc/sysconfig/libvirtd

LIBVIRTD_ARGS="--listen"

$ sudo cp /etc/libvirt/libvirtd.conf /etc/libvirt/libvirtd.conf.`date +%F`
$ sudo vim /etc/libvirt/libvirtd.conf

listen_tls = 0
listen_tcp = 1
listen_addr = "0.0.0.0"
auth_tcp = "none"

log_outputs="3:syslog:libvirtd"

$ sudo service libvirtd restart

$ sudo firewall-cmd --add-rich-rule='rule family="ipv4" source address="172.17.71.32/30" port port="16509" protocol="tcp" accept'

$ virsh -r -c 'qemu+tcp://mgmt@kvm46.example.com/system' list --all
