CONTEXT = [ hostname = "MAINHOST", ip_private = "$NIC[IP, NETWORK="public net"]", dns = "$NETWORK[DNS, NETWORK_ID=0]", root_pass = "$IMAGE[ROOT_PASS, IMAGE_ID=3]", ip_gen = "10.0.0.$VMID", files_ds = "$FILE[IMAGE="certificate"] $FILE[IMAGE="server_license"]" ]

Context information is passed to the Virtual Machine via an ISO mounted as a partition. This information can be defined in the VM template in the optional section called Context, with the following attributes: 上下文信息是通过ISO安装为一个分区传递给虚拟机。此信息可 在可选的部分称为上下文在VM模板定义的，具有以下属性：

Windows Provisioning a Windows VM is performed the standard way in OpenNebula:

  1. Register the Installation media (typically a DVD) into a Datastore

  2. Create an empty datablock with an appropriate size, at least 10GB. Change the type to OS. If you are using a qcow2 image, don’t forget to add DRIVER=qcow2 and FORMAT=qcow2.

  3. Create a template that boots from CDROM, enables VNC, and references the Installation media and the Image created in step 2.

  4. Follow the typical installation procedure over VNC.

  5. Perform a deferred disk-snapshot of the OS disk, which will be saved upon shutdown.

  6. Shutdown the VM.
