oVirt-4.x 配置IP地址登录 In a web browser, navigate to https://manager-fqdn/ovirt-engine, replacing manager-fqdn with the FQDN that you provided during installation.You can access the Administration Portal using alternate host names or IP addresses. To do so, you need to add a configuration file under /etc/ovirt-engine/engine.conf.d/. For example:# vi /etc/ovirt-engine/engine.conf.d/99-custom-sso-setup.conf # SSO_ALTERNATE_ENGINE_FQDNS="alias1.example.com alias2.example.com" SSO_ALTERNATE_ENGINE_FQDNS="192.168.0.xx"The list of alternate host names needs to be separated by spaces. You can also add the IP address of the Engine to the list, but using IP addresses instead of DNS-resolvable host names is not recommended.Click Administration Portal. An SSO login page displays. SSO login enables you to log in to the Administration and VM Portal at the same time.Enter your User Name and Password. If you are logging in for the first time, use the user name admin along with the password that you specified during installation.Select the Domain to authenticate against. If you are logging in using the internal admin user name, select the internal domain.Click Log In.You can view the Administration Portal in multiple languages. The default selection is chosen based on the locale settings of your web browser. If you want to view the Administration Portal in a language other than the default, select your preferred language from the drop-down list on the welcome page.To log out of the oVirt Administration Portal, click your user name in the header bar and click Sign Out. You are logged out of all portals and the Engine welcome screen displays.

OSI参考模型 1.OSI参考模型优点OSI模型是层次型的，具有所有分层模型的所有优点和好处，所有分层模型的主要目的是为了让不同厂商的网络能够互操作。2.使用OSI分层模型主要有以下几点：将网络通信过程划分成更小、更简单的组件。这有助于组件的开发、设计和故障排除；通过标准化网络组件，能够让多家厂商协作开发；定义了模型每层执行的功能；可以让不同类型的网络硬件和软件彼此通信；避免对其中一层的修改影响其它层，从而避免妨碍开发工作。3.OSI参考模型OSI规范最大的作用之一是帮助不同的主机之间进行数据传输，OSI模型包含7层，它们分为两组：上3层指定了终端的应用程序如何彼此通信以及如何与用户交流。下4层指定了如何进行端到端的数据传输。名称说明应用层提供用户界面表示层表示数据，进行加密等处理会话层将不同应用程序的数据分离传输层提供可靠或不可靠的传输，在重传前执行纠错网络层提供逻辑地址，路由器使用它们来选择路径数据链路层将分组拆分成字节，并将字节组合成帧，使用MAC地址提供介质访问，执行纠错检测，但不纠错物理层在设备之间传输比特，指定电平、电缆速度和电缆针脚
