### Nova libvirt-xen driver and patch (Feb 2015) in upstream libvirt ?

@stefano question is addressed to you.
Per http://www.slideshare.net/xen_com_mgr/openstack-xenfinal, page 18 ( Feb 2015)

 2 patches under review for Nova ( it's done I know)
1 patch in upstream in libvirt (?)


Which one in upstream libvirt , if it's accepted and there is commit record, then which one ?
It's also obvious that this patch cannot be in libvirt 1.2.2 ( standard for Ubuntu 14.04) and upgrade to 1.2.9
doesn't help much. It's not a problem to build Libvirt from source, which version is required ?
Why page http://wiki.xen.org/wiki/OpenStack_via_DevStack keeps silence regarding need of recent libvirt patch
Feb 2015 ?
I have escalated this question to Xen-devel mailing list
along with bug
and get no response from the author on Wiki page above.

You also stated on page 18

Everything works out of the box
Using the latest Openstack and libvirt trees


You meant that latest libvirt tree is supposed to be cloned to Ubuntu 14.04 , been built and installed ?
I am not sure latest Libvirt version would work with Xen 4.4.1 coming with Trusty
