Nova-conductor puts instance in error if an unknown exception is raised in the _build_live_migrate_task during the live-migration. [1] The exception comes from _call_livem_checks_on_host and we can see raise exception.MigrationPreCheckError if we face to messaging.MessagingTimeout exception for example. [2] The function check_can_live_migrate_destination does a check also on source host with check_can_live_migrate_source [3] and this check can also return exceptions like MessagingTimeout and this one is not caught properly because it's a remote "Remote error: MessagingTimeout" due to dest host try to contact source host and this source host not reply.

============== OpenStack Nova ============== OpenStack Nova provides a cloud computing fabric controller, supporting a wide variety of compute technologies, including: libvirt (KVM, Xen, LXC and more), VMware and OpenStack Ironic. Use the following resources to learn more. API --- To learn how to use Nova's API, consult the documentation available online at: - `Compute API Guide <https://docs.openstack.org/api-guide/compute/>`__ - `Compute API Reference <https://docs.openstack.org/api-ref/compute/>`__ For more information on OpenStack APIs, SDKs and CLIs in general, refer to: - `OpenStack for App Developers <https://www.openstack.org/appdev/>`__ - `Development resources for OpenStack clouds <https://developer.openstack.org/>`__ Operators --------- To learn how to deploy and configure OpenStack Nova, consult the documentation available online at: - `OpenStack Nova <https://docs.openstack.org/nova/>`__ 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: - `Bug Tracker <https://bugs.launchpad.net/nova>`__ 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. To understand better the processes that the team is using, please refer to the `Process document <https://docs.openstack.org/nova/latest/contributor/process.html>`__. Further developer focused documentation is available at: - `Official Nova Documentation <https://docs.openstack.org/nova/>`__ - `Official Client Documentation <https://docs.openstack.org/python-novaclient/>`__ Other Information ----------------- During each `Summit`_ and `Project Team Gathering`_, we agree on what the whole community wants to focus on for the upcoming release. The plans for nova can be found at: - `Nova Specs <http://specs.openstack.org/openstack/nova-specs/>`__ .. _Summit: https://www.openstack.org/summit/ .. _Project Team Gathering: https://www.openstack.org/ptg/
