There's no formal process mandated for libvirt. Either people just send
code patches directly, or for more complex features like this, start off
with a mailing list discussion about design decisions before writing
patches. Libvirt releases once a month so there's no critical deadlines
you need to rush to meet from upstream POV - they'll merge in whatever
release is next once the code has passed review. For complex code it
is common to post several versions adapting to review comments.

In terms of merging code, if it depends on QEMU, then we require that
the QEMU impl is merged before the libvirt impl is merged. We'd encourage
you to develop & publish libvirt patches before QEMU work is finalized.
This helps demonstrate that the QEMU impl is a good match for what libvirt
needs.

This is probably more a question for the OpenStack community to answer.
The goal with Libvirt is to expose the feature in XML and/or API in a
way that is suitable for any mgmt application.
