Terraform provider for oVirt
by Sandro Bonazzola 15 May '18

Hi, just following up from twitter[1], if any developer within oVirt knows about Terraform, there's interest on their side for collaboration developing a provider. For more info, see the github issue: https://github.com/hashicorp/terraform/issues/16150 [1] https://twitter.com/jepeltw/status/955647436931858432 -- SANDRO BONAZZOLA ASSOCIATE MANAGER, SOFTWARE ENGINEERING, EMEA ENG VIRTUALIZATION R&D Red Hat EMEA <https://www.redhat.com/> <https://red.ht/sig> TRIED.

Mailing-Lists upgrade

This is an OpenPGP/MIME signed message (RFC 4880 and 3156) --IfGqXrbgT9wNNdIsvS8kI8WdhEQHlgkiq Content-Type: multipart/mixed; boundary="AUFHCWPQQknM84fF2kF4uGjIv4blC9bMv"; protected-headers="v1" From: =?UTF-8?B?TWFyYyBEZXF1w6huZXMgKER1Y2sp?= <duck(a)redhat.com> To: oVirt Infra <infra(a)ovirt.org>, users <users(a)ovirt.org>, devel <devel(a)ovirt.org> Message-ID: <c5c71fce-0290-e97a-ddd0-eab0e6fccea4(a)redhat.com> Subject: Mailing-Lists upgrade --AUFHCWPQQknM84fF2kF4uGjIv4blC9bMv Content-Type: text/plain; charset=utf-8 Content-Language: en-US Content-Transfer-Encoding: quoted-printable Quack, On behalf of the oVirt infra team, I'd like to announce the current Mailing-Lists system is going to be upgraded to a brand new Mailman 3 installation on Monday during the slot 11:00-12:00 JST. It should not take a full hour to migrate as we already made incremental synchronization with the current system but better keep some margin. The system will then take over delivery of the mails but might be a bit slow at first as it needs to reindex all the archived mails (which might take a few hours). To manage your subscriptions and delivery settings you can do this easily on the much nicer web interface (https://lists.ovirt.org) There is a notion of account so you don't need to login separately for each ML.= You can Sign In using Fedora, GitHub or Google or create a local account if you prefer. Please keep in mind signing in with a different method would create separate accounts (which cannot be merged at the moment). But you can easily link your account to other authentication methods in your settings (click on you name in the up-right corner -> Account -> Account Connections). As for the original mail archives, because the previous system did not have stable URLs, we cannot create mappings to the new pages. We decided to keep the old archives around on the same URL (/pipermail), so the Internet links would still work fine. Hope you'd be happy with the new system. \_o< --AUFHCWPQQknM84fF2kF4uGjIv4blC9bMv-- --IfGqXrbgT9wNNdIsvS8kI8WdhEQHlgkiq Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEcpcqg+UmRT3yiF+BVen596wcRD8FAlmwx0MACgkQVen596wc RD9LTQ/+LtUncsq9K8D/LX8wqUTd6VyPwAD5UnAk5c3H/2tmyVA0u7FIfhEyPsXs Z//LE9FEneTDqDVRi1Dw9I54K0ZwxPBemi71dXfwgBI7Ay0ezkbLWrA168Mt9spE tHAODEuxPt2to2aqaS4ujogrkp/gvEP8ILoxPEqoTPCJ/eDTPAu/I1a2JzjMPK3n 2BBS6D8z0TLAf7w1n72TsgX2QzJW57ig/0HELyjvat2/K8V3HSrkwiKlsdULQDWe zB+aMde7r6UoyVKHqlu4asTl2tU/lGZ+e31Hd9Bnx1/oZOJdzslGOhEo9Qoz6763 AHWU9LKiK4NtxYHj2UQTWhndr8PiTtTmR73eIDmkb0cuRXxzjl9VQbwYJ0Kbrmfp attTqpc2CnEojTNXUUNSmNxotZoYXZiX8ZvjPfSgRVr15TUYujzlOfG+lUynbQMV 9rQ9/m58wgwYUymMpOIsRGaIcAKzjm+WpuuVnO+bS2AfmcBkGMQRoIhfV+3SkS8q kT9cDXgcDZOzVFcnZZB4EjbycMcPgZDcoHxU88VdYH+jFJYvvb21esgswVF/wJ2Z uEI/chp4+ADaQhl8ehZNWMSZq125v6SeirPhBNgLG7zFVZI1S9Tm/6qFmH+ajQY7 nCk1X9HZlB1ubex1X+HibRz9QKOilkMgkADyJ4yMDckwYj93sx0= =l6uN -----END PGP SIGNATURE----- --IfGqXrbgT9wNNdIsvS8kI8WdhEQHlgkiq--

You make a good point on why it is not (at least for existing apps). However, since this was optional, the way this would look without the XML abstraction is that both input and output would be valid domain definitions, ultimately resulting in something similar to virt-xml with the added benefit of applying a policy from a file/string either supplied by the application itself. Whether that policy was taken from a common repository of such knowledge is orthogonal to this idea. Since you would work with the same data, the upgrade could be incremental as you'd only let virtuned fill in values for new options and could slowly move on to using it for some pre-existing ones. None of the previous approaches did this, if I'm not mistaken. Of course it gets more difficult when you need to expose all the bits libvirt does and keep them in sync (as you write below).

I did a tiny PoC based on the code from virt-manager, which was trivial mainly thanks to the XMLBuilder for the domain objects. Maybe exposing an easy way to work with the XML would be enough for some projects. Little birdie from oVirt told me that they would like some of sort of thing that does what you can achieve with virt-xml if we, for example, made it work on pure XML definitions without connecting to libvirt. >> - I know KubeVirt has VirtualMachinePresets.

I didn't feel very optimistic about the upstream acceptance for that idea, so I figured that there could be something that lives beside libvirt, helps with some policies if requested and then the resulting XML could be fed into libvirt for determining the rest. >There's also the problem with use of native libraries that would >impact many apps.

So maybe instead of focusing on de-duplication of existing codebases we could _at least_ aim at future mgmt apps.

oVirt log analyzer
by Milan Zamazal 04 Apr '18

04 Apr '18

Hi, during last year Outreachy internship a tool for analyzing oVirt logs was created. When it is provided with oVirt logs (such as SOS reports, logs gathered by Lago, single or multiple log files) it tries to identify and classify important lines from the logs and present them in a structured form. Its primary purpose is to get a quick and easy overview of actions and errors. The tool analyses given logs and produces text files with the extracted information. There is an Emacs user interface that presents the output in a nice way with added functionality such as filtering. Emacs haters can use the plain text files or write another user interface. :-) You can get ovirt-log-analyzer from https://github.com/mz-pdm/ovirt-log-analyzer README.md explains how to use it. Note that ovirt-log-analyzer has been created within the limited resources of an Outreachy internship with some additional work and not everything is perfect. Feel free to make improvements. Regards, Milan

new time-based test randomly failing
by Dan Kenigsberg 29 Mar '18

I suppose this test should be reworked, or at least, have its constants tweaked.

OST Failure - Weekly update [24/03/2018-29/03/2018]
by Dafna Ron 29 Mar '18

29 Mar '18

Hello, I would like to update on this week's failures and OST current status. This week I am sending the report a bit earlier due to the holidays. We had a few failures this week but I am glad to report that the issues were fixed quickly. on 23-03-2018 we started getting a random failure which seems to be an issue with the ost test hotplug_cpu This fix was submitted by Milan to fix the issue: https://gerrit.ovirt.org/89589 On the 27-03-2018 we had a failure on basic_sanity.disk_operations This seems to be related to locking race and was fixed by Benny on 3 different fixes: https://gerrit.ovirt.org/#/c/89534/ https://gerrit.ovirt.org/#/c/89537/ https://gerrit.ovirt.org/#/c/89577/ There was an issue with build-artifacts on the vdsm project which was an infra failure as well as a code issue (2 different builds). this was also resolved quickly. Infra issues: The ci team discovered and fixed a failure in container cleanup on the the hosts. Daniel submitted this patch: https://gerrit.ovirt.org/#/c/89402/ and it seemed to have resolved the issue. Gal has been investigating an issue which causes failure due to lack of memory on the host. for now, Gal submitted a fix: https://gerrit.ovirt.org/#/c/89588/ Lastly we had a packaging issue on 4.2 which was resolved as well. *Below you can see the chart for this week's resolved issues but cause of failure:Code* = regression of working components/functionalities *Infra* = infrastructure/OST Infrastructure/Lago related issues/Power outages *OST* Tests - package related issues, failed build artifacts *Below is a chart of resolved failures based on ovirt version* *Below is a chart showing failures by suite type: * *Thanks, * *Dafna*
