Boris, thank you for your feedback.

Unfortunately, it is extraordinary hard to track in your emails what is
your addition, and what was cited from the earlier mail.

Would it be possible for you to make it more clear? I.e. no inline edits?

Thank you.

Hi,

Until now, the openstack-nova package in RDO had a lax requirement on
qemu-kvm which potentially meant an older version of qemu-kvm (or
qemu-kvm-rhel) would be installed [1].

We have agreed at the RDO meeting this morning to go ahead and
formally require qemu-kvm >= 2.3 from Newton onwards.
This means that the base (~v1.5.3) qemu-kvm from CentOS (or
qemu-kvm-rhel in RHEL) will no longer satisfy that requirement.

The CentOS virt SIG maintains qemu-kvm-ev (>=2.3) which obsoletes
qemu-kvm and will be preferred if it is available.
This newer version is largely preferred to the one available by
default in CentOS and RHEL due to improvements, bug fixes and features
that are expected to be there by Nova.

If you consume RDO's master trunk repositories (Delorean
Newton/Delorean Master), this extra repository is already enabled in
delorean-deps.repo [3] and you do not need to do anything.
qemu-kvm-ev will automatically be installed in place of qemu-kvm.

If you consume RDO from stable releases, the extra repository will
automatically be enabled in the "centos-release-openstack-newton"
package that will eventually be available.
The repository will also be bundled in the "rdo-release.rpm" package
[4] starting at Newton.

Please let us know if you have any questions or notice any issues.

Thanks !

My notice :-

TripleO QuickStart fails to work with VIRTHOST running qemu-kvm-ev-2.3
and does work after downgrade ( with all dependencies brought back )
to standard qemu-kvm -1.5 for CentOS 7.2. Please, make TripleO Quicstart Team
aware of oncoming changes.

I wrote it mostly for attention of John Trowbridge and Lars Kellogg Stedman.

Does it make things more clear ?

Boris
