/**
* Creates a new virtual machine.
*
* The virtual machine can be created in different ways:
*
* - From a template. In this case the identifier or name of the template must be provided. For example, using a
* plain shell script and XML:
*
* [source,bash]
* ----
* #!/bin/sh -ex
*
* url="https://engine.example.com/ovirt-engine/api"
* user="admin@internal"
* password="..."
* curl \
* --verbose \
* --cacert /etc/pki/ovirt-engine/ca.pem \
* --user "${user}:${password}" \
* --request POST \
* --header "Version: 4" \
* --header "Content-Type: application/xml" \
* --header "Accept: application/xml" \
* --data '
*
* myvm
*
* Blank
*
*
* mycluster
*
*
* ' \
* "${url}/vms"
* ----
*
* - From a snapshot. In this case the identifier of the snapshot has to be provided. For example, using a plain
* shel script and XML:
*
* [source,bash]
* ----
* #!/bin/sh -ex
*
* url="https://engine.example.com/ovirt-engine/api"
* user="admin@internal"
* password="..."
* curl \
* --verbose \
* --cacert /etc/pki/ovirt-engine/ca.pem \
* --user "${user}:${password}" \
* --request POST \
* --header "Content-Type: application/xml" \
* --header "Accept: application/xml" \
* --data '
*
* myvm
*
*
*
* mycluster
*
*
* ' \
* "${url}/vms"
* ----
*
* When creating a virtual machine from a template or from a snapshot it is usually useful to explicitly indicate
* in what storage domain to create the disks for the virtual machine. If the virtual machine is created from
* a template then this is achieved passing a set of `disk_attachment` elements that indicate the mapping:
*
* [source,xml]
* ----
*
* ...
*
*
*
*
*
*
*
*
*
* ----
*
* When the virtual machine is created from a snapshot this set of disks is slightly different, it uses the
* `image_id` attribute instead of `id`.
*
* [source,xml]
* ----
*
* ...
*
*
*
* 8d4bd566-6c86-4592-a4a7-912dbf93c298
*
*
*
*
*
*
* ----
*
* It is possible to specify additional virtual machine parameters in the XML description, e.g. a virtual machine
* of `desktop` type, with 2 GiB of RAM and additional description can be added sending a request body like the
* following:
*
* [source,xml]
* ----
*
* myvm
* My Desktop Virtual Machine
* desktop
* 2147483648
* ...
*
* ----
*
* A bootable CDROM device can be set like this:
*
* [source,xml]
* ----
*
* ...
*
*
*
* ----
*
* In order to boot from CDROM, you first need to insert a disk, as described in the
* <>. Then booting from that CDROM can be specified using the `os.boot.devices`
* attribute:
*
* [source,xml]
* ----
*
* ...
*
*
*
* cdrom
*
*
*
*
* ----
*
* In all cases the name or identifier of the cluster where the virtual machine will be created is mandatory.
