3.16. 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'.

本例从虚拟机的 cdrom 集合中弹出 ISO 镜像。

    url='https://engine.example.com/ovirt-engine/api',
    username='admin@internal',

# Get the reference to the "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 VM:
cdroms_service = vm_service.cdroms_service()

# Get the first found CDROM:
cdrom = cdroms_service.list()[0]

# Locate the service that manages the CDROM device found in previous step
# of the VM:
cdrom_service = cdroms_service.cdrom_service(cdrom.id)

cdrom_service.remove()

print("Removed CD from '%s'." % vm.name())

connection.close()

如果删除 或删除 请求成功，则示例输出文本：

Removed CD from 'vm1'.
