this is the inital patch of applying codespell to nova. codespell is a programing focused spellchecker that looks for common typos and corrects them. i am breaking this into multiple commits to make it simpler to read and will automate the execution of codespell at the end of the series.

upgrade:
|
|
- |
|
|
In the libvirt driver, the default value of the ``<cputune><shares>``
|
|
element has been removed, and is now left to libvirt to decide. This is
|
|
because allowed values are platform dependent, and the previous code was
|
|
not guaranteed to be supported on all platforms. If any of your flavors are
|
|
using the quota:cpu_shares extra spec, you may need to resize to a
|
|
supported value before upgrading.
|
|
|
|
To facilitate the transition to no Nova default for ``<cputune><shares>``,
|
|
its value will be removed during live migration unless a value is set in
|
|
the ``quota:cpu_shares`` extra spec. This can cause temporary CPU
|
|
starvation for the live migrated instance if other instances on the
|
|
destination host still have the old default ``<cputune><shares>`` value. To
|
|
fix this, hard reboot, cold migrate, or live migrate the other instances.
