oVirt on Fedora 28 for developers
by Nir Soffer 29 Jun '18

29 Jun '18

I want to share the current state of oVirt on Fedora 28, hopefully it will save time for other developers. 1. Why should I run oVirt on Fedora 28? - Fedora is the the base for future CentOS. The bugs we find *today* on Fedora 28 are the bugs that we will not have next year when we try oVirt on CentOS. - I want to contribute to projects that require python 3. For example, virt-v2v require python 3.6 in upstream. If you want to contribute you need to test it on Fedora 28. - I need to develop with latest libvirt and qemu. One example is incremental backup, you will need Fefora 28 to work on this. - CentOS is old and boring, I want to play with the newest bugs :-) 2. How to install oVirt with Fedora 28 hosts Warning: ugly hacks bellow! - Install ovirt-release-master.rpm on all hosts dnf install http://resources.ovirt.org/pub/yum-repo/ovirt-release-master.rpm - Install or build engine on CentOS 7.5 (1804)[1] - When provisioning a host, make sure you have lvm2-2.02.177-5.fc28 without it, no block storage you[2] - When adding a host, disable "Configure host firewall" - it does not work now I hope that Sandro team will fix this issue soon. - Adding a host will fail, because without firewall setup, port 54321 is not reacable. to fix this, configure the firewall manually, or disable it iptables -F This is pretty lame because you have to apply it again after restart, but it was good enough for now. - Because the host was not reachable, we don't configure the host network so the host will be non-operational. To fix this, open host > network > setup networks and assign ovirtmgmt to the host management nic. The host will become UP after that. I hope that Dan team will fix it soon. - Adding storage will fail because sanlock selinux issue[3] To fix, set selinux to permissive mode: setenforce 0 At this point you should have a working setup. 3. Building and instaling vdsm from source on Fedora 28 - Install build dependencies using dnf install `cat automation/check-patch.packages.fc28` - Clean the source (needed if you rerun ./autogen.sh with different options) git clean -dxf - Configure vdsm with hooks - for some reason 2 hooks are required on Fedora but not on EL. ./autogen.sh --system --enable-hooks - Build make make rpm - Install the packages at /home/user/rpmbuild/RPMS/{noarch,x86_64} - if vdsm was never installed, you need to configure and enable it vdsm-tool configure --force systemctl enable vdsmd systemctl start vdsmd At this point you can test the new bugs you added to vdsm :-) [1] I did not try to install engine on Fedora 28. I guess engine folks can share if there are issues with this. [2] https://bugzilla.redhat.com/1575762 LVM team fixed the issue couple of hours after I asked about it in #lvm We had a build for testing couple of days later. [3] https://bugzilla.redhat.com/1593853 We are still waiting for selinux folks response. Happy hacking! Nir

[VDSM] Why hooks are required for installing vdsm?
by Nir Soffer 28 Jun '18

28 Jun '18

Trying to update vdsm master, my update script fail with: installing... error: Failed dependencies: vdsm = 4.30.0-429.git05bfb8731.fc28 is needed by (installed) vdsm-hook-fcoe-4.30.0-429.git05bfb8731.fc28.noarch vdsm = 4.30.0-429.git05bfb8731.fc28 is needed by (installed) vdsm-hook-ethtool-options-4.30.0-429.git05bfb8731.fc28.noarch I tried to remove these hooks, since I'm not interested in any of them, but removing them try to remove 136 packages including libvirt. Why do we have these dependencies? hook should be optional. Who owns these hooks? Nir

Adding Fedora 28 host to engine 4.2 (NotImplementedError: Packager install not implemented)
by Nir Soffer 27 Jun '18

27 Jun '18

I'm trying to add a host running Fedora 28 to engine 4.2, and installation fails with: 2018-06-20 01:14:26,137+0300 DEBUG otopi.context context._executeMethod:143 method exception Traceback (most recent call last): File "/tmp/ovirt-Z5BGYej3Qa/pythonlib/otopi/context.py", line 133, in _executeMethod method['method']() File "/tmp/ovirt-Z5BGYej3Qa/otopi-plugins/ovirt-host-deploy/vdsm/vdsmid.py", line 84, in _packages self.packager.install(('dmidecode',)) File "/tmp/ovirt-Z5BGYej3Qa/pythonlib/otopi/packager.py", line 102, in install raise NotImplementedError(_('Packager install not implemented')) NotImplementedError: Packager install not implemented 2018-06-20 01:14:26,138+0300 ERROR otopi.context context._executeMethod:152 Failed to execute stage 'Environment packages setup': Packager install not implemented Do we have a way to workaround this? I must have a host when I can build and test virt-v2v upstream from source, and virt-v2v requires python 3. So I need some workaround to get the host connected to engine. Nir

UI plugin API updates
by Vojtech Szocs 26 Jun '18

26 Jun '18

Hi everyone, just a heads-up on recent UI plugin API changes. *oVirt 4.2* 4.2.5+ will support "icon" option when adding new menu item & content via addMainTab API function [1]. Both Font Awesome and PatternFly icons are supported [2]. api.addMainTab('Test', 'fooBar', 'plugin/plugin-name/test.html', { icon: 'fa-lock' // icon: 'pficon-security' }); [1] https://bugzilla.redhat.com/1591730 [2] https://www.patternfly.org/styles/icons/ *oVirt** master* You can now use showToast API function [3] to render "toast" notifications in top right corner of the page. api.showToast('success', 'Operation completed successfully.'); The first parameter can be "info" (white), "success" (green), "warning" (yellow) or "danger" (red). [3] https://gerrit.ovirt.org/#/c/92354/ Regards, Vojtech

vm portal UI redesign -- weekly report Hi, Note: A team is working on redesigning the UI of vm portal. This is the first edition of my weekly status report on this project. [tl;dr pretty screens: https://github.com/oVirt/ovirt-design/pull/6] project book: n/a (using github issues [1] and ovirt-design [2]) trello: none (Note: we have been using a google doc [3], but because it's not publicly visible upstream, we are transitioning to github [2].) Status: * last week we iterated on Jenny's design updates. * Tomas posted a patch to give us everything needed in the API. * The inline edit page is very close to final UI. * Liz is beginning interaction design on Add VM. * Current designs a missing the network graph -- that can come back. It should look identical to the CPU and Memory, a single total Bandwidth. So three pies. * 'Other OS' icon looks awesome but will neutralize the color (gray) * change 'asleep' --> 'suspended' * Marek + Bohdan + Scott are now coding. * Scott can begin immediately with cards that talk to the stats service, and probably others, and will demo a prototype this week *Action items* *Scott*: prototype of the VM details page - functioning CPU, Memory, and Network cards - and as much as possible of everything else :) *Jenny*: - confirmation popups for 'Remove' VM and other actions (ask Marek / Scott for all such actions -- stop, force stop, delete, others?) - console dialog (console options, edit connection type) - options dialog (ssh key) - add a network card, connect it to a network (just a listbox) - button bar changing when VM is in different states - add disks - create snapshot - gray the Other OS icon *Liz*: - new VM flow (could feature explode -- may want to mimic cockpit's design) *Marek / Bohdan*: - continue coding / creating github issues [1] github issues: Redesign main page · Issue #641 · oVirt/ovirt-web-ui https://github.com/oVirt/ovirt-web-ui/issues/641 Designer review of VM Detail page · Issue #596 · oVirt/ovirt-web-ui https://github.com/oVirt/ovirt-web-ui/issues/596 convert 'force' actions to secondary dropdown pattern · Issue #588 · oVirt/ovirt-web-ui https://github.com/oVirt/ovirt-web-ui/issues/588 use modal dialog pattern instead of popover · Issue #587 · oVirt/ovirt-web-ui https://github.com/oVirt/ovirt-web-ui/issues/587 [2] https://github.com/oVirt/ovirt-design/pull/6 [3] https://docs.google.com/presentation/d/1UavAccggYAqLeXZYnVpyiE6h5tnCJJQMq_f… Best wishes, Greg -- GREG SHEREMETA SENIOR SOFTWARE ENGINEER - TEAM LEAD - RHV UX Red Hat NA <https://www.redhat.com/> gshereme(a)redhat.com IRC: gshereme <https://red.ht/sig>

Deprecating direct RPM downloads from Jenkins
by Barak Korren 24 Jun '18

24 Jun '18

Hi there, TL;DR: Is your build/CI/other process consuming RPMs directly from Jenkins? Could it be changed to consume from other available places? In STDCI V1 we supported obtaining of the latest CI build for a particular project in a particular branch on a particular platform directly from Jenkins, by using the "latestSuccessfulBuild" dynamic link that Jenkins generates. This was possible in STDCI V1 because we had one-to-one correlation between jenkins jobs and project/branch/platform combinations. That is no longer the case in STDCI V2 where each project gets just two fixed jobs that adjust themselves automatically to run needed functionality. We could implement some equivalent functionality in STDCI V2 by for e.g. uploading builds to some predictable locations on an artifact server, but that will take some non-trivial amount of work, so it leads us to the question if this functionality is really needed. There are a couple of alternatives locations to get recently built packages from: - The 'tested' repo which contains all the packages that passed CQ/OST - The 'snapshot' repo which contains a nightly snapshot of 'tested'. So given the options above, if you have a build/CI/other process that currently consumes builds from Jenkins, could it be changed to consume from the other available locations? -- Barak Korren RHV DevOps team , RHCE, RHCi Red Hat EMEA redhat.com | TRIED.
