= Agenda =

* OpenStack Summit recap (if needed)
Bob: BoF we managed was well attended - was mostly a presentation. But we
did manage to get to discuss
Bob: Did meet with a few key people who operate CI loops
Stefano: Discussion on Definition of Hypervisor support Matrix - no
decisions were made
Stefano: Intention is to have a more fine-grained quality status
Stefano: We are in group B and will stay there in the near future
Jim: Is Xen + Libvirt in support group B
Bob: Yes, correct
Stefano: next action is to talk to John Garbutt to figure out criteria to
move to group A
Bob: John is going to get in touch with Lars

ACTION(Stefano, Lars): Arrange meeting with John Garbutt

* Transfer of account to Xen Project
Bob let me know the costs for running the CI loop and I would like move
the CI loop to a Xen Project account. I would like to understand the
practical issues and put together a rough plan. That is within the
Advisory Board's budget.

Server cost for Feb 21 to Mar 21: $1223
Server cost for Mar 21 to Apr 21: $1744 â but thatâs end-of-cycle rush so
would be higher than normal traffic.
Then there is a small extra cost for cloud files storage and CDN, but I
canât split that out but estimate $50 per month.
On average Iâd guess that might be $1,500 per month or maybe $18k
per-annum 

Steps needed:
Bob: 1st step is to get the accounts set up
Bob: Once accounts are set up, this is going to be straight forward and
move things over
Bob: Not going to move over, but just transfer credentials in the source

Ant: We do have a developer plan without support
Bob: Is not quite sure, usage is pretty straight forward (spinning stuff
up and down)
Ant: Thinks we probably won't need support
Bob: Mostly control plane issues, but no general config issues

ACTION(Lars): look into this via the website - developer program. Create
account.
ACTION(Lars): to figure out how to bill this against the project

Bob: Need to transfer repository credentials into a public xenbits repo
Lars: IanJ & IanC can set this up

* Open Bugs / Fixing Bugs / Fixing Races
A) Find a fix for https://bugs.launchpad.net/nova/+bug/1445443
(related to the two tests we disabled)
Bob: Have this disabled, there is a fix in the upstream kernel
Bob: Not something in our environment
Bob: Should we try and get the fix into the environment or carry on with
disabled tests
AnthonyP: Have a fix with an unreleased kernel

*Plan, leave in launchpad until the next Ubuntu Release. *
*Make clear that we do not intend to do anything until there is a released
version of the kernel*

B) Older open bugs that need attention:
https://bugs.launchpad.net/openstack/+bugs?field.searchtext=libvirt+xen&ord
erby=-importance&search=Search&field.status%3Alist=NEW&field.status%3Alist=
CONFIRMED&field.status%3Alist=TRIAGED&field.status%3Alist=INPROGRESS&field.
status%3Alist=INCOMPLETE_WITH_RESPONSE&field.status%3Alist=INCOMPLETE_WITHO
UT_RESPONSE&assignee_option=any&field.assignee=&field.bug_reporter=&field.b
ug_commenter= (some are feature wishlist items)

Bob: 2 of the low ones are interesting
Bob: #1450465 vif name too long when libvirt driver trying to create XEN
HVM domain <https://bugs.launchpad.net/nova/+bug/1450465> - neutron
related, which we have to fix if we want to go to neutron

Bob: Wishlist - not necessarily needed for group B & A
Jim: read-only mode should work, so this is a bug that ought to be fixed
Stefano: it looks as if we need to fix some of these

Bob: Should we document Xen+Libvirt support in OpenStack manuals
Lars: happy to pick up docs stuff if someone is willing to work with me.
Can also rope in Russell

ACTION (Lars): to talk to Bob/Antony re docs

https://bugs.launchpad.net/tempest/+bug/1443898 - has an unaccepted patch.
Lars: do we need to ping people to get it looked at
Bob: Has a -1, so we may need to address feedback first
AnthonyP: send link to patch to include  (patch 180161,
https://review.openstack.org/#/c/180161/)
 
Races / Intermittent test failures

Bob: Instabilities in CI environment. Antony has discovered two classes of
errors in the CI results, which are races which have not yet been created
AnthonyP: Nova / Network interaction when we create a guest via libvirt /
xl - sometimes the script fails, leading to test failures. Not sure how to
succeed.

Lars: should we CC Jim when there are libvirt related issues.
Bob: thinks it is possible to add a list / alias to launchpad (try)

*Agree to CC Jim and Konrad when new issues are discovered.*

Jim: highlighted that one of the bugs also fails OSSTEST (qemu doesn't
start)
Jim: Has been trying to reproduce it locally.
AnthonyP: Also been trying to reproduce, with little success
Bob: Don't have a reproduction case
Lars: Does it make sense for Jim and Antony to work together
Jim: Has a patch that may fix the issue (cleans up ref counting in the
driver - something similar was done in the qemu driver, as qemu had
similar issues)

Jim: has the patch and has tested it - test has run for days

Action(Lars): see whether we can add a list or alias to launchpad

Action(Jim): send patch to Antony directly (because Jim is on vacation)

* Knowledge sharing - I need to agree date and set up the meeting
http://lists.xenproject.org/archives/html/xen-devel/2015-03/msg02211.html
fell through the cracks

Action(Bob): pick up the thread again and agree time
Action(Bob): add Michael Glasgow to xen-devel@ thread

* Switching to Neutron

Bob: world is moving away from nova network to neutron
Bob: What is the plan - do we have a plan - on moving to neutron

AnthonyP: #1450465 vif name too long when libvirt driver trying to create
XEN HVM domain <https://bugs.launchpad.net/nova/+bug/1450465> is blocking
move to neutron

*Agreement, try and fix the bug and see whether this will fix neutron
support as a first step*
