[TripleO] Yoga PTG timeslots vote
by Marios Andreou 20 Jul '21

20 Jul '21

Hello TripleO in case you missed the announcement from Ashlee at [1] the yoga ptg will be on October 18-22. We need to decide on the timeslot to use so we can reserve a room to meet. I started a doodle poll at [2] please indicate which time works best for you. The times in the doodle poll are UTC so you need to work out what it means for your location. I arbitrarily chose tuesday 19th but same times will apply to all days. In the last two virtual PTGs used the 1300-1700 UTC - so sanity check does this time still work best for the majority of our community? Rooms should be reserved by July 21 so lets close this poll on Tue 20 and we can discuss if needed during the scheduled irc meeting on the 20th. thanks, marios [1] http://lists.openstack.org/pipermail/openstack-discuss/2021-July/023540.html [2] https://doodle.com/poll/mre6tghmbntbivdd

Re: Setting bandwidth limit
by Rodolfo Alonso Hernandez 20 Jul '21

20 Jul '21

Hello Felipe: Did you configure both the server and the agent? Probably you configured the server correctly, this is why you can create and apply the QoS policies. But you also need to configure the OVS agent [1]. In the plugin ML2 config (by default /etc/neutron/plugins/ml2/ml2_conf.ini), you need to configure the agent extension: [agent]extensions = qos Check this config file and then enable the OVS agent debug logs (restarting the agent). Check the logs for any QoS message there. You should also check: - For BW limit ingress rules (ingress from the VM point of view, this is the default point of view): the OVS agent creates a QoS register and a queue register in the OVS DB table. You should see them using ovs-vsctl tool. - For BW limit egress: the OVS agent modifies the port Interface table, setting the "ingress_policing_rate" and "ingress_policing_burst" (we don't do traffic shaping, we drop packets exceeding the max rate but it works). I hope that helps you to debug what is happening there. Regards.

[rpm-packaging] logging override in openstack packages
by Piotr Mossakowski 20 Jul '21

20 Jul '21

Hello, There is a logging override in almost all openstack packages, for example in nova: https://opendev.org/openstack/rpm-packaging/src/branch/stable/victoria/open… <https://opendev.org/openstack/rpm-packaging/src/branch/stable/victoria/open…> It lands in /etc/nova/nova.conf.d/010-nova.conf as stated in the spec: https://opendev.org/openstack/rpm-packaging/src/branch/stable/victoria/open… <https://opendev.org/openstack/rpm-packaging/src/branch/stable/victoria/open…> Let's assume following scenario: in kolla-ansible based deployment I want to disable logging globally using /etc/kolla/config/global.conf: [DEFAULT] log_dir = log_file = For kolla images built from RPMs, the file '/etc/nova/nova.conf.d/010-nova.conf' will override what I want to achieve by global.conf. We have a situation when kolla images log inside the container into '/var/log/nova' where there is no log rotation. There is no easy way to change that in kolla-ansible based deployments. Is there any specific reason why default logging has been hardcoded like that? Can we agree to change that situation to be able to override logging as expected? -- Pozdrawiam serdecznie / Best regards, *Piotr Mossakowski* Lead System Engineer, Product Development Services, Cloud Infra & Applications Email piotr.mossakowski(a)tietoevry.com <mailto:piotr.mossakowski@tietoevry.com>, +48795515407 <tel:%2B48795515407> Aleja Piastów 30, 71-064 Szczecin, Poland, www.tietoevry.com <http://www.tieto.com/>

[kolla][wallaby][manila] urgent: new BUG ???
by Ignazio Cassano 20 Jul '21

20 Jul '21

Hello, probably we discovered a new bug in kolla wallaby manila generic driver. Starting by victoria release, the manila share conf requires the section [glance] otherwise it cannot create the service instance. We modified the manila conf inserting the section [glance] like the following: [glance] auth_uri = http://10.102.119.194:5000 auth_url = http://10.102.119.194:35357 auth_type = password project_domain_id = default user_domain_id = default region_name = RegionOne endpoint_type = internalURL project_name = service username = glance password = password cafile = memcache_security_strategy = ENCRYPT memcache_secret_key = password memcached_servers = 10.102.119.195:11211,10.102.119.196:11211, 10.102.119.197:11211 And now it can create the service instance. Could anyone verify it, please ? Ignazio

PTG October 2021 Team Signup
by Ashlee Ferguson 19 Jul '21

19 Jul '21

Hi everyone, Last week, we announced the next PTG will held virtually from Monday, October 18 to Friday, October 22, 2021. We will have the same schedule set up available as last time with three windows of time spread across the day to cover all timezones with breaks in between. To signup your team, you must complete BOTH the survey[1] AND reserve time in the ethercalc[2] by end of day July 21. We ask that the PTL/SIG Chair/Team lead sign up for time to have their discussions with 3 rules/guidelines: 1. Cross project discussions (like SIGs or support project teams) should be scheduled towards the start of the week so that any discussions that might shape those of other teams happen first. 2. No team should sign up for more than 4 hours per UTC day to help keep participants actively engaged. 3. No team should sign up for more than 16 hours across all time slots to avoid burning out our contributors and to enable participation in multiple teams discussions. Again, you need to fill out BOTH the ethercalc AND the survey to complete your team's sign up. If you have any issues with signing up your team, due to conflict or otherwise, please let me know! While we are trying to empower you to make your own decisions as to when you meet and for how long (after all, you know your needs and teams timezones better than we do), we are here to help! Once your team is signed up, please register[3]! And remind your team to register! Registration is free, but it's important that you sign up to let us know you'll be attending because that's how you'll receive event details, passwords, and other relevant information about the PTG. Continue to visit openstack.org/ptg for updates. Ashlee [1] Team Survey: https://openinfrafoundation.formstack.com/forms/oct2021_vptg_survey [2] Ethercalc Signup: https://ethercalc.openstack.org/8tum5yl1bx43 [3] PTG Registration: https://openinfra-ptg.eventbrite.com

VM Migration To New Hardware with OpenStack
by KK CHN 19 Jul '21

19 Jul '21

QUERY Section A: We are in the process of migrating VMs from a Vendor to OpenStack . The Vendor has hosted the VMs using RedHat Virtualization and HyperV around 100 VMs. Each VM size varies from 50 GB to 150 GB size. What is the best way to migrate these VMs to New Hardware infra Installed with OpenStack Ussuri. What need to be done at the existing live VMs with the Vendor and in what file format we have to ask the vendor to give the snapshot of VMs to be migrated ? I am new to the migration of VMs from a live production setup ( the present Vendor deployed VMs with all aplications running on the VM with HyperV and RedeHat KVM. ) We are also using KVM hypervisor. Kindly advise and direct me with all good practices followed to perform this migration from existing vendor to our own setup with OpenStack and KVM. Pls shed some light on this. QUERY SECTION B Another question below ffor a trail the existing vendor has given a demo VM, which is a Windows VM with an ERP application hosted on it . But the vendor handed over three files of single VM , Three qcow2 files. They handed over three qcow2 files for this VM as follows. 1. First file is OS image as qcow2 2. /boot as another qcow2 image 3. /lv-datat as another qcow2 image How to combine these files and we can create a Running VM from these files and put it on bare metal installed with KVM only. Is this possible ? How ? What need to take care while doing this operation?. your hints and direcitons highly appreciated. Thanks in Advance, Kris
