[openstack-dev] RFC: Potential to increase min required libvirt version to 0.9.8 ?

Currently the Nova libvirt driver is declaring that it wants a minimum
of libvirt 0.9.6.
For cases where we use features newer than this, we have to do conditional
logic to ensure we operate correctly on old libvirt. We don't want to keep
adding conditionals forever since they complicate the code and thus impose
an ongoing dev burden.
I think it is wise to re-evaluate the min required libvirt version at the
start of each dev cycle. To do this we need to understand what versions
are available in the OS distributions we care about supporting for the
To this end I've created a wiki page covering Debian, Fedora, OpenSUSE,
RHEL and Ubuntu
Considering those distros it looks like we can potentially increase the
min required libvirt to 0.9.8 for Icehouse.
If there are other distros I've missed which expect to support deployment
of Icehouse please add them to this list. Hopefully there won't be any
with libvirt software older than Ubuntu 12.04 LTS....
The reason I'm asking this now, is that we're working to make the libvirt
python module a separate tar.gz that can build with multiple libvirt
versions, and I need to decide how ancient a libvirt we should support
