Description John Snow 2019-03-20 16:09:00 UTC
This bug is a clone of the Bitmap management API request for a finalized backup API cloned for NBD. They have been split to ease burden of review and to separate areas of focus.

This is effectively a tracker for backporting the NBD patches from this pull request upstream:

and possibly these:

+++ This bug was initially created as a clone of Bug #1668956 +++

Description of problem:

The pull-model incremental backup API still uses commands like "x-block-dirty-bitmap-disable" and several others. The API should be finalized for use by Libvirt/RHV and others.

Version-Release number of selected component (if applicable):

Seen in 7.7's qemu-kvm-rhev-2.12.0; fixed upstream in QEMU 3.1 development branches.
