Subject: virt-xml: Add support for starting the domain
From: Marc Hartmayer mhartmay@linux.ibm.com Tue Feb 26 10:56:43 2019 +0100

Git: 90b1a3ab7d9cb9c84e7dda7093ae2c97217fa591

Add support for starting the domain. By default, first the domain is
defined and then started. If the `--start` is used in combination with
`--no-define` a transient domain is created without persisting the
changes in the persistent domain definition.
