[libvirt] [PATCH 0/3] Couple of src/Makefile.am fixes
by Michal Privoznik 31 Aug '15

31 Aug '15

I've noticed that 'make distcheck' is failing. While investigating that issue I've came up with some other checks too. Preferably, I'd like to get these into the current release (the fix 2/3 at least).

[libvirt] [PATCH] migration: remove direct migration dependency on version1 of driver
by Nikolay Shirokovskiy 31 Aug '15

31 Aug '15

From: Nikolay Shirokovskiy <Nikolay Shirokovskiy nshirokovskiy(a)virtuozzo.com> Direct migration should work if *perform3 is present but *perform is not. This is situation when driver migration is implemented after new version of driver function is introduced. We should not be forced to support old version too as its parameter space is subspace of newer one.

[libvirt] Entering freeze for libvirt-1.2.19
by Daniel Veillard 31 Aug '15

31 Aug '15

So I have tagged rc1 in git and pushed signed tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ The release works just fine in my limited testing, but others should try it out to check portability and more advanced functionalities. I will likely push rc2 at the end of the week-end and the final release on Tuesday or Wednesday, assuming no big issue is raised in the meantime. thanks for giving it a try. I also note that we have some CI test failing, not for core libvirt but perl bindings, virt-manager, ... it would be good to investigate before we push the release: https://ci.centos.org/view/libvirt-project/ thanks !
