3.16. 将 ISO 镜像附加到虚拟机
要在新创建的虚拟机上安装客户端操作系统,您必须附加包含操作系统安装介质的 ISO 文件。要找到 ISO 文件,请参阅 列出 ISO 存储域中的文件。
例 3.14. 将 ISO 镜像附加到虚拟机
本示例将 my_iso_file.iso 附加到 vm1
虚拟机,并使用虚拟机的 cdroms
集合的 add
方法。
V4
import ovirtsdk4 as sdk import ovirtsdk4.types as types connection = sdk.Connection( url='https://engine.example.com/ovirt-engine/api', username='admin@internal', password='password', ca_file='ca.pem', ) # Get the reference to the "vms" service: vms_service = connection.system_service().vms_service() # Find the virtual machine: vm = vms_service.list(search='name=vm1')[0] # Locate the service that manages the virtual machine: vm_service = vms_service.vm_service(vm.id) # Locate the service that manages the CDROM devices of the virtual machine: cdroms_service = vm_service.cdroms_service() # Get the first CDROM: cdrom = cdroms_service.list()[0] # Locate the service that manages the CDROM device found in previous step: cdrom_service = cdroms_service.cdrom_service(cdrom.id) # Change the CD of the VM to 'my_iso_file.iso'. By default the # operation permanently changes the disk that is visible to the # virtual machine after the next boot, but has no effect # on the currently running virtual machine. If you want to change the # disk that is visible to the current running virtual machine, change # the `current` parameter's value to `True`. cdrom_service.update( cdrom=types.Cdrom( file=types.File( id='my_iso_file.iso' ), ), current=False, ) print("Attached CD to '%s'." % vm.name()) # Close the connection to the server: connection.close()
如果 添加
请求成功,则输出文本的示例:
Attached CD to 'vm1'.
例 3.15. 从虚拟机中弹出一个 CDROM
本例从虚拟机的 cdrom
集合中弹出 ISO 镜像。
