4.3.5. 对大量 v2v 操作进行脚本自动化

过程 4.9. 配置并运行大量 v2v 操作的自动化脚本

1. 确认 Red Hat Enterprise Virtualization Manager 启用了 REST API，并可以被运行 v2v 脚本的 Linux 访问。如需了解更多关于 REST API 的信息，请参阅 Red Hat Enterprise Virtualization Developer Guide。
2. 在 Linux 主机上，创建包括以下内容的 v2v.sh 文件。请确认您根据您的具体环境对脚本中的相应内容进行了修改。

   例 4.5. 单独主机的 v2v 脚本

   #!/bin/sh
   # Declare all VMs to import
   XENDOMAINS=("rhelxen" "rhel5")
   KVMDOMAINS=("rhelkvm")
   VMWAREVMS=("rhel54vmware")
   
   # Iterate through each Xen domain, performing the conversion
   for domain in ${XENDOMAINS[@]}
   do
           virt-v2v -ic xen:///localhost -o rhev -os storage.example.com:/exportdomain --network rhevm $domain
   done
   
   # Iterate through each KVM domain, performing the conversion
   for domain in ${KVMDOMAINS[@]}
   do
           virt-v2v -o rhev -os storage.example.com:/exportdomain --network rhevm $domain
   done

   注意

   使用 POST 方法来通过 REST API 导出虚拟机。如需了解更多关于 REST API 的信息，请参阅 Red Hat Enterprise Virtualization Developer Guide。
3. 运行 v2v.sh 脚本。这可能需要几个小时才能完成转换并导入大量虚拟机的操作。
