Maciej Józefczyk c9b74bcfa0 Update resources once in update_available_resource
This change ensures that resources are updated only once per
update_available_resource() call.

Compute resources were previously updated during host
object initialization and at the end of
update_available_resource(). It could cause inconsistencies
in resource tracking between compute host and DB for couple
of second when final _update() at the end of
update_available_resource() is being called.

For example: nova-api shows that host uses 10GB of RAM, but
in fact its 12GB because DB doesn't have resources that belongs
to shutdown instance.

Because of that fact nova-scheduler (CachingScheduler) could
choose (based on imcomplete information) host which is already full.

For more informations please see realted bug: #1729621

OpenStack Nova

OpenStack Nova provides a cloud computing fabric controller, supporting a wide variety of compute technologies, including: libvirt (KVM, Xen, LXC and more), Hyper-V, VMware, XenServer, OpenStack Ironic and PowerVM.

Use the following resources to learn more.

API

To learn how to use Nova's API, consult the documentation available online at:

For more information on OpenStack APIs, SDKs and CLIs in general, refer to:

Operators

To learn how to deploy and configure OpenStack Nova, consult the documentation available online at:

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.

Further developer focused documentation is available at:

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:
