Background
==========
The blueprint [1] wants to utilize the *virtlogd* logging deamon from
libvirt. Among others to solve bug [2], one of our oldest ones. The
funny part is, that this libvirt feature is still in development. This
was a trigger to see if we can create a gate job which utilizes the
latest, bleeding edge, version of libvirt to test such features. We
discussed it shortly in IRC [3] (tonyb, bauzas, markus_z) and wanted to
get some feedback here. The summary of the idea is:
* Create a custom repo which contains the latest libvirt version
* Enhance Devstack so that it can point to a custom repo to install
the built libvirt packages
* Have a nodepool image which is compatible with the libvirt packages
* In case of [1]: check if tempest needs further/changed tests
Open questions
==============
* Is already someone working on something like that and I missed it?
Sean (cc'd) might have some information on what he's doing in the OVS w/
DPDK build environment, which AFAIK requires a later build of libvirt
than available in most distros.
* If 'no', is there already a repo which contains the very latest
libvirt builds which we can utilize?
I haven't done anything with the gates before, which means there is a
very high chance I'm missing something or missunderstanding a concept.
Please let me know what you think.
A generic "build libvirt or OVS from this source repo" dsvm job would be
great I think. That would allow overrides in ENV variables to point the
job to a URI for grabbing sources of OVS (DPDK OVS, mainline OVS) or
libvirt that would be built into the target nodepool images.
Thoughts?
Best,
