3.12. Creating a Virtual Disk
To ensure that a newly created virtual machine has access to persistent storage you must create and attach a disk.
This Ruby example creates and attaches a virtual storage disk to a virtual machine.
# 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=myvm')[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( OvirtSDK4::DiskAttachment.new( disk: { name: 'mydisk', description: 'My disk', format: OvirtSDK4::DiskFormat::COW, provisioned_size: 10 * 2**30, storage_domains: [{ name: 'mydata' }] }, interface: OvirtSDK4::DiskInterface::VIRTIO, bootable: false, 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) loop do sleep(5) disk = disk_service.get break if disk.status == OvirtSDK4::DiskStatus::OK end
