3.15. 创建虚拟机磁盘

这个示例创建了一个 8 GB VirtIO 磁盘，并将其附加到虚拟机 vm1。这个磁盘有以下要求：

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',
)

# Locate the virtual machines service and use it to find the virtual
# machine:
vms_service = connection.system_service().vms_service()
vm = vms_service.list(search='name=vm1')[0]

# Locate the service that manages the disk attachments of the virtual
# machine:
disk_attachments_service = vms_service.vm_service(vm.id).disk_attachments_service()

# Use the "add" method of the disk attachments service to add the disk.
# Note that the size of the disk, the `provisioned_size` attribute, is
# specified in bytes, so to create a disk of 10 GiB the value should
# be 10 * 2^30.
disk_attachment = disk_attachments_service.add(
    types.DiskAttachment(
        disk=types.Disk(
            format=types.DiskFormat.COW,
            provisioned_size=8*1024*1024,
            storage_domains=[
                types.StorageDomain(
                    name='data1',
                ),
            ],
        ),
        interface=types.DiskInterface.VIRTIO,
        bootable=True,
        active=True,
    ),
)

# Wait until the disk status is OK:
disks_service = connection.system_service().disks_service()
disk_service = disks_service.disk_service(disk_attachment.disk.id)
while True:
    time.sleep(5)
    disk = disk_service.get()
    if disk.status == types.DiskStatus.OK:
        break

print("Disk '%s' added to '%s'." % (disk.name(), 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：

Disk 'vm1_Disk1' added to 'vm1'.
