[docs] Project guides in PDF format
by Peter Matulis 07 Apr '21

07 Apr '21

Hello, I understand that there was a push [1] to make PDFs available for download from the published pages on docs.openstack.org for the various guides (Sphinx projects). Is there any steam left in this initiative? The next best thing is to have something at the repository level that people can work with. Currently, there are a limited number of guides that can be converted to PDF from the openstack-manuals repository. What is the suggested implementation for individual projects? Thanks, Peter Matulis [1]: https://etherpad.opendev.org/p/train-pdf-support-goal

[dev][nova] Problem about vm migration compatibility check
by Guoyi Tu 07 Apr '21

07 Apr '21

hi there, In my test environment, i created a vm and configured the cpu with host-model, when I migrate the vm to another host with the same cpu, it failed the migration compatibility check which complains the cpu definition of domain is incompatible with target host cpu. As we know, when the domain configured as above starts, the host-model cpu definition will automatically converted to custom cpu model and with some addtional features that the KVM supported, these addtional features may contains features that the host doesn't support. In the code, the compatibility of the target host is check by calling compareCPU()(libvirt API). The compareCPU() can only recongnize the features probed by cpuid instruction on the host, but it may not recognize the features of cpu definition of domain xml (virsh dumpxml domainname) when the domain running. So the compatibility check will fail when KVM support one or more features which is considerd as disabled by the cpuid instuction. I think we should call compareHypervisorCPU() or something like that (supported by libvirt since v4.4.0) instead of compareCPU() to check the migration compatibility. My test environment is as follow: host cpu: Cascadelake libvirt-6.9 qemu-5.0 host-model cpu: <mode name='host-model' supported='yes'> <model fallback='forbid'>Cascadelake-Server</model> <vendor>Intel</vendor> <feature policy='require' name='ss'/> <feature policy='require' name='hypervisor'/> <feature policy='require' name='tsc_adjust'/> <feature policy='require' name='umip'/> <feature policy='require' name='pku'/> <feature policy='require' name='md-clear'/> <feature policy='require' name='stibp'/> <feature policy='require' name='arch-capabilities'/> <feature policy='require' name='xsaves'/> <feature policy='require' name='invtsc'/> <feature policy='require' name='rdctl-no'/> <feature policy='require' name='ibrs-all'/> <feature policy='require' name='skip-l1dfl-vmentry'/> <feature policy='require' name='mds-no'/> <feature policy='require' name='pschange-mc-no'/> <feature policy='disable' name='hle'/> <feature policy='disable' name='rtm'/> </mode> The hypervisor, umip, pschange-mc-no features block the compatibility check -- Best Regards, Guoyi Tu

How to modify staging-ovirt parameters
by Gianluca Cecchi 07 Apr '21

07 Apr '21

Hello, I have a test lab with Queens on CentOS 7 deployed with TripleO, that I use sometimes to mimic an OSP 13 environment. The Openstack nodes are oVirt VMS. I moved these VMs from one oVirt infrastructure to another one. The Openstack environment starts and operates without problems (3 controllers, 2 computes and 3 cephs), but I don't know how to modify the staging-ovirt parameters. At oVirt side I re-created as before a user ostackpm@internal with sufficient power and I also set the same password. But the ip address of the engine cannot be the same. When I deployed the environment I put all the parameters inside the instackenv.json file to do introspection and deploy. Where are they put on undercloud? Is there a way to update them? Perhaps some database entries or other kind of repos where I can update the ip? Thanks in advance, Gianluca

Unable to retrieve ceph docker image for Queens
by Gianluca Cecchi 07 Apr '21

07 Apr '21

Hello, I'm trying to extend an old small test lab Queens environment with dedicated Ceph Storage nodes. I would like to add some disks to the storage nodes and so I customize my original templates/ceph-config.yaml adding them under devices section: parameter_defaults: CephAnsibleDisksConfig: osd_scenario: lvm osd_objectstore: bluestore devices: - /dev/sda - /dev/sdb - /dev/sdc . . . When I run the overcloud deploy I get this in ceph-install-workflow.log 2021-04-06 21:24:57,955 p=32618 u=mistral | TASK [ceph-docker-common : pulling docker.io/ceph/daemon:v3.2.10-stable-3.2-luminous-centos-7-x86_64 image] *** 2021-04-06 21:24:57,955 p=32618 u=mistral | Tuesday 06 April 2021 21:24:57 +0200 (0:00:00.153) 0:06:17.978 ********* 2021-04-06 21:25:13,206 p=32618 u=mistral | FAILED - RETRYING: pulling docker.io/ceph/daemon:v3.2.10-stable-3.2-luminous-centos-7-x86_64 image (3 retries left). . . . 2021-04-06 21:26:03,715 p=32618 u=mistral | FAILED - RETRYING: pulling docker.io/ceph/daemon:v3.2.10-stable-3.2-luminous-centos-7-x86_64 image (1 retries left). 2021-04-06 21:26:28,839 p=32618 u=mistral | fatal: [172.23.0.232]: FAILED! => {"attempts": 3, "changed": false, "cmd": ["timeout", "300s", "docker", "pull", "docker.io/ceph/daemon:v3.2.10-stable-3.2-luminous-centos-7-x86_64"], "delta": "0:00:15.022274", "end": "2021-04-06 21:25:48.701980", "msg": "non-zero return code", "rc": 1, "start": "2021-04-06 21:25:33.679706", "stderr": "Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)", "stderr_lines": ["Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)"], "stdout": "Trying to pull repository docker.io/ceph/daemon ...

[all] Octavia LoadBalancer Error
by Adekunbi Adewojo 06 Apr '21

06 Apr '21

Hi there, I recently deployed a load balancer on our openstack private cloud. I used this manual - https://docs.openstack.org/octavia/latest/user/guides/basic-cookbook.html to create the load balancer. However, after creating and trying to access it, it returns an error message saying "No server is available to handle this request". Also on the dashboard, "Operating status" shows offline but "provisioning status" shows active. I have two web applications as members of the load balancer and I can individually access those web applications. Could someone please point me in the right direction? Thanks.

[tripleo] master and victoria promotions delayed
by Wesley Hayutin 06 Apr '21

06 Apr '21

0/ Hey just want to communicate that promotions for master and victoria are being delayed due to promotion-blockers. If you have a merged patch in a repo that is not gated by tripleo jobs you will NOT be able to use that patch until we promote. http://dashboard-ci.tripleo.org/d/HkOLImOMk/upstream-and-rdo-promotions?org… Please review the following bugs to better understand what is blocking. https://bugs.launchpad.net/tripleo/+bugs?field.tag=promotion-blocker&orderb… I'll note, any tempest test results logged in bugs are most likely already skipped and not blocking upstream via https://opendev.org/openstack/openstack-tempest-skiplist/src/branch/master/… Your focus should be on deployment failures, not tempest failures at this time. Thank you!
