[barbican] PTL non-candidacy
by Ade Lee 05 Mar '19

05 Mar '19

With the PTL self nomination period starting this week, I wanted to say that I will not be running for PTL this cycle. The PTL experience is great, but its a position that should rotate often. With new leadership comes new energy, new ideas and new directions. I'll still be heavily involved in Barbican project regardless. Ade

[sdk] Proposing Artem Goncharov (gtema) for core
by Monty Taylor 05 Mar '19

05 Mar '19

Hey everybody, I'd like to propose making gtema core on openstacksdk. He regularly reviews all the stuff coming through, even the crazy stuff I generate, and those reviews are thorough without being nitpicky. He's definitely caught mistakes I'e made with my brainhole. He's also been doing a bunch of great dev work which shows a good understanding of the mechanics of the codebase. This includes but is not limited to the recent addition of DNS support as well as increasing our glance coverage. Not just that though - when faced with "yeah, that's great, but we need to add some deep systemic support for a new underlying concept before you can add that feature" he totally went off and did the slog of updating the guts first. All in all, he's totally active in the project and has shown a good understanding of what's going on. Thoughts? Monty

Re: [nova][dev] Any VMware resource pool and shares kind of feature available in openstack nova?
by Sanjay K 05 Mar '19

05 Mar '19

Hello Chris, Thank you for your reply. To give you more clarity on my question, let me describe my goal which I am trying to achieve through openstack nova. scenario 1- say in a compute node, I have some development and production VMs hosted. So in that compute node, production VMs will have more priority than development VMs to contend for compute resources (RAM, vcpus, disk etc). case 2. when both prod and dev VMs are on a compute node, if one user reboots one production VM which was in shutdown/not-running state, the compute node should take this VM resource allocation as priority and readjust/redistribute resources among other existing VMs so that this VM should get the adequate or more resources for which it was initially created with. If it does not find the required resources on that compute, it should migrate or launch this VM on a different compute node based on user consent or just after giving some notification to user that this VM is started on a different compute. case 3. when multiple users simultaneously starts some dev and prod VMs, the production VMs should always get the resources allocated first from the compute. Then the other low priority VMs should get their resources share. In my case, the development and production VMs belong to different subnets. If I know correctly, there is no way nova is doing resource allocation dynamically to VMs once they are hosted on a compute node. It just takes the filters and weights to decide which compute the instance should run. I think the above decision can be handled before filtering and weighing phase kicks in to decide how much resource one VM should be given to. I find the preemptible instances feature useful after going through the discussions/videos, but not sure as of now whether it will solve my cases completely. Please lee me know what you think. thank you for precious inputs. best rgds

[virtualbmc] Serial console support in virtualbmc
by Lars Kellogg-Stedman 05 Mar '19

05 Mar '19

Hey folks, I wanted serial-over-lan support in virtualbmc so that I can use it for testing while working on getting nova-serialproxy support into tripleo. It turns out that sol support had shown up early in 2018 [1], but was subsequently pulled [2] due to a file descriptor leak. I've tried to rewrite the sol implementation to avoid the file descriptor leak; you can see my work so far in: https://review.openstack.org/#/c/640888/4 It Works For Me at this point. If this is something that interests you I would welcome your feedback. The change is currently marked WIP because there are numerous unit tests that need to be rewritten.

[sahara] PTL Non-Candidacy
by Telles Nobrega 05 Mar '19

05 Mar '19

With the PTL self-nomination period starting this week [0], I wanted to say that I won't be running for the role again. Even though being PTL is a great experience I don't believe that it should stay on the same hands for too long. New eyes, new direction, new priorities are a great oppportunity for the growth of a project. With that in mind, I'm here to support anyone who is willing to run for the post. If you're thinking about running and have questions, please don't hesitate to ask. I'm happy to share my experience. If you know someone who would do well in the position, you should encourage them to run. Thanks for all the time you trusted in me on this role, [0] https://releases.openstack.org/stein/schedule.html#t-ptl-nominations -- TELLES NOBREGA SOFTWARE ENGINEER Red Hat Brasil <https://www.redhat.com/> Av.

[TripleO] boot from SAN via FCoE
by Tomáš Bredár 05 Mar '19

05 Mar '19

Hi, I'm struggling with an issue, hopefully someone from this list could help me. Problem: I'm deploying OpenStack Queens with TripleO and would like to deploy my overcloud nodes to disks on my SAN environment. I use virtual-connect flexfabric interfaces and this provides FCoE connection to my nodes. In order to see the LUNs from the SAN in Centos I need to install fcoe-utils package and configure the corresponding eth interfaces. For this I need to build the overcloud-full image and the ironic-python-agent image to support this and to be able see the disk drives during introspection. I was looking for an image element for fcoe boot in [1], but there's none. I tried to make my custom one, but with no luck yet. I can't figure out how to make my SAN driver visible via FCoE during introspection. Is there anyone who had a similar issue and solved it? Thanks Tomas [1] https://github.com/openstack/diskimage-builder/tree/master/diskimage_builde…
