[octavia] problems configuring octavia
by Daniel Macdonald 12 Jan '21

12 Jan '21

Happy new year Openstack users and devs! I have been trying on and off for several months to get octavia working but I have yet to have it successfully create a loadbalancer. I have deployed OS bionic-train using the Charms telemetry bundle with the octavia overlay. Openstack is working for creating regular instances but I get various errors when trying to create a loadbalancer. The first issue I feel I should mention is that I am using bind running on our MAAS controller as a DNS server. juju doesn't work if I enable IPv6 under bind yet the octavia charm defaults to using IPv6 for its management network so I have tried creating a IPv4 management network but I'm still having problems. For more details on that please see the comments of this bug report: https://bugs.launchpad.net/charm-octavia/+bug/1897418 Bug #1897418 “feature request: have option to use ipv4 when sett...” : Bugs : OpenStack Octavia Charm<https://bugs.launchpad.net/charm-octavia/+bug/1897418> By default, Octavia charm uses ipv6 for its lb-mgmt-subnet.[1] It would be nice to have the option to choose an ipv4 network from the start instead of deleting the ipv6 network and recreating the ipv4 subnet. Implementation - possible configuration option parameter when deploying. [1] https://opendev.org/openstack/charm-octavia/src/branch/master/src/lib/charm… bugs.launchpad.net Another notable issue I have is that after installing the charms telemetry bundle I have 2 projects call services. How do I know which is the correct one to use for Octavia? Is this following document going to be the best guide for me to follow to complete the final steps required to get Octavia (under Train) working: https://docs.openstack.org/octavia/latest/install/install-ubuntu.html#insta… OpenStack Docs: Install and configure for Ubuntu<https://docs.openstack.org/octavia/latest/install/install-ubuntu.html#insta…> Install and configure for Ubuntu¶. This section describes how to install and configure the Load-balancer service for Ubuntu 18.04 (LTS). docs.openstack.org I'm hoping someone has already written an easy to follow guide to using Octavia with an IPv4 management network using the Charms bundle to do most of the installation work?

[oslo][TC] Dropping lower-constraints testing
by hberaud 11 Jan '21

11 Jan '21

Hello, As you already surely know, we (the openstack project) currently face some issues with our lower-constraints jobs due to pip's latest resolver feature. By discussing this topic with Thierry Carrez (ttx) from an oslo point of view, we reached the same conclusion that it is more appropriate to drop this kind of tests because the complexity and recurring pain needed to maintain them now exceeds the benefits provided by this mechanismes. Also we should notice that the number of active maintainers is declining, so we think that this is the shortest path to solve this problem on oslo for now and for the future too. In a first time I tried to fix our gates by fixing our lower-constraints project by project but with around ~36 projects to maintain this is a painful task, especially due to nested oslo layers inside oslo himself... I saw the face of the hell of dependencies. So, in a second time I submitted a series of patches to drop these tests [1]. But before moving further with that we would appreciate discussing this with the TC. For now the patches are ready and we just have to push the good button accordingly to our choices (+W or abandon). Normally all the oslo projects that need to be fixed are covered by [1]. Thoughts? Thanks for reading.

[nova] unit testing on ppc64le
by Balazs Gibizer 11 Jan '21

11 Jan '21

Hi, We have a bugreport[1] showing that our unit tests are not passing on ppc. In the upstream CI we don't have test capability to run our tests on ppc. But we have the IBM Power KVM CI[2] that runs integration tests on ppc. I'm wondering if IBM could extend the CI to run nova unit and functional tests too. I've added Michael Turek (mjturek(a)us.ibm.com) to CC. Michael is listed as the contact person for the CI. Cheers, gibi [1]https://bugs.launchpad.net/nova/+bug/1909972 [2]https://wiki.openstack.org/wiki/ThirdPartySystems/IBMPowerKVMCI

[nova] [Ussuri] Unable to perform live block migrations on ephemeral VMs without shared storage
by Justin Goetz 08 Jan '21

08 Jan '21

Hello! Happy new year to everyone! I'm experiencing some trouble in my attempts to get live block migrations working on machines who's boot drives live on ephemeral (local) host storage. Offline (cold) migrations appear to work fine, however, I need live migrations to function with no downtime to the VMs. We're running on OpenStack Ussuri, with Ubuntu 18.04.5 LTS as our hypervisor OS, running libvirt 6.0.0. Below is the following command I'm utilizing to perform the live block migration: openstack server migrate <id> --debug --verbose --live-migration --block-migration The verbose logging of the above command shows no obvious issues, however digging deeper on the hypervisor side, we see some libvirtd errors, and the most telling is this segment here: Jan 08 16:53:02 h5 libvirtd[4118]: Unsafe migration: Migration without shared storage is unsafe Jan 08 16:53:02 h5 nova-compute[130270]: 2021-01-08 16:53:02.860 130270 ERROR nova.virt.libvirt.driver [-] [instance: 72bc9feb-b8f0-45f2-bad4-9cb61c3abff3] Live Migration failure: Unsafe migration: Migration without shared storage is unsafe: libvirt.libvirtError: Unsafe migration: Migration without shared storage is unsafe Full log output is available here: http://paste.openstack.org/show/801525/ Perhaps I'm severely mistaken, but native libvirt should have no problem whatsoever performing live migrations without shared storage on it's own. I've dug into the libvirt side for hours to try and troubleshoot what the system is seeing as "unsafe" (I confirmed disk caching is disabled, as well as no strange custom settings are present), but was unsuccessful. The full output of my VM's QEMU XML file can be viewed here: http://paste.openstack.org/show/801526/ As I couldn't figure out why libvirtd was not seeing the migration as "safe", I attempted to override the libvirt message by attempting to utilize the live_migration_flag and block_migration_flag options in nova.conf to invoke the --unsafe parameter when running the libvirt commands (with the flags VIR_MIGRATE_UNDEFINE_SOURCE,VIR_MIGRATE_PEER2PEER,VIR_MIGRATE_LIVE,VIR_MIGRATE_UNSAFE,VIR_MIGRATE_NON_SHARED_INC), however I later learned from a previous developers thread on the mailing list from 2016 that both of these options have been depreciated in the later versions of Nova and replaced by the "live_migration_tunnelled" setting in nova.conf. I've ensured my nova.conf files have the live_migration_tunnelled parameter set to "True". However, I have not found any method for passing along the "--unsafe" flag (or any other libvirt flag, in this case) to libvirt from nova.conf from this point on after the depreciation of the live_migration_flag parameters. Any help would be greatly appreciated, from reading around online this seems to be a fairly common setup, I'm baffled at how I've run into this issue across several separate OpenStack clusters at this point.

how to read ipa source code#ironic-python-agent
by Ankele zhang 08 Jan '21

08 Jan '21

Hi~ I have an OpenStack platform on Rocky, and I used Nova/Keystone/Cinder/Glance/Ceph/Ironic. Recently, I have build my own ironic-python-agent deployment ramdisk and kernel images by ironic-python-agent-builder, the following work is to add my customized raid configuration method to HardwareManager. Before this, I want to read the ipa's source code. But I don't know where is the 'main()' entry. Looking forward to your help. Ankele
