Mohammed Naser 643f53f5e9 libvirt: Avoid setting MTU during live migration if unset
If there is a live migration of an instance that was launched
before change Iecc265fb25e88fa00a66f1fd38e215cad53e7669, it
would not have an mtu set and therefore it wouldn't have it in
the XML.

When live migrating, the mtu is added which changes the
guest ABI[1], causing the live migration to fail.  The failure
occurs when trying to live migrate an instance that:

- Launched before change Iecc265fb25e88fa00a66f1fd38e215cad53e7669
- It has not been rebooted (i.e. XML has not changed since)
- It's using bridge/tap networking
- Migration attempted after change Iecc265fb25e88fa00a66f1fd38e215cad53e7669

This patch prevents this by avoiding setting MTU if the running
instance does not have one configured in its domain XML.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:

Developers

For information on how to contribute to Nova, please see the contents of the CONTRIBUTING.rst.

Any new code must follow the development guidelines detailed in the HACKING.rst file, and pass all unit tests.
