Public bug reported: We merged this backport in stable/ocata which went into the 15.0.6 and 15.0.7 releases:
https://review.openstack.org/#/c/471353/ But later realized (when reviewing the stable/newton proposed backport) that the VIR_DOMAIN_BLOCK_REBASE_COPY_DEV flag is only available to libvirt starting in 1.2.9. We only started requiring libvirt >= 1.2.9 starting in the pike release, and in ocata we require libvirt >= 1.2.1. So anyone with libvirt < 1.2.9 that picks up this change in ocata and is doing a swap volume operation with a block volume could hit an AttributeError. https://libvirt.org/git/?p=libvirt.git;a=blob;f=docs/news-2014.html.in https://libvirt.org/git/?p=libvirt.git;a=commit;h=b7e73585a8d96677695a52bafb156f26cbd48fb5 ** Affects: nova Importance: Undecided Status: Invalid ** Affects: nova/ocata Importance: Medium Status: Triaged ** Tags: libvirt volumes ** Also affects: nova/ocata Importance: Undecided Status: New ** Changed in: nova/ocata Status: New => Triaged ** Changed in: nova Status: Triaged => Invalid ** Changed in: nova/ocata Importance: Undecided => Medium ** Changed in: nova Importance: Medium => Undecided -- You received this bug notification because you are a member of Yahoo!
