3.19. 使用 Overridden 参数启动虚拟机

本示例使用 Windows ISO 引导虚拟机并附加 virtio-win_x86.vfd 软盘磁盘，其中包含 Windows 驱动程序。此操作等同于使用管理门户中的 Run Once 窗口启动虚拟机。

# 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 'windows_example.iso':
cdrom_service.update(
    cdrom=types.Cdrom(
        file=types.File(
            id='windows_example.iso'
        ),
    ),
    current=False,
)

# Call the "start" method of the service to start it:
vm_service.start(
    vm=types.Vm(
        os=types.OperatingSystem(
            boot=types.Boot(
                devices=[
                    types.BootDevice.CDROM,
                ]
            )
        ),
    )
)

# Wait until the virtual machine's status is "UP":
while True:
    time.sleep(5)
    vm = vm_service.get()
    if vm.status == types.VmStatus.UP:
        break

print("Started '%s'." % vm.name())

# Close the connection to the server:
connection.close()
