VM support for Infiniband
by Kevin Hung 01 Oct '16

01 Oct '16

Hello, I have been trying (unsuccessfully) to add my Infiniband HCAs on my VM hosts to oVirt 4.0.4. I am not using IBoIP, just plain Infiniband. I would like to be able to pass through the card (or better yet the VF from SR-IOV) to the guest VM. From what I can figure out, oVirt is trying to bridge the interface but I don't think that will work as shown here [1]. Does oVirt currently have support for passing through Infiniband to VMs? If not, are there any plans to support it? [1] http://lists.ovirt.org/pipermail/users/2016-July/040898.html Thanks, Kevin Hung

Migrating self hosted engine from iSCSI to NFS ?
by Matteo 30 Sep '16

30 Sep '16

Hi all, I've a 2 hosts setup with ovirt 4, with a bunch of machines on it. I started with an old iSCSI unit, then added a new NFS storage server and started moving all VMs. All VMs have been migrated over NFS (live storage migration works great!), but now I need to move also the hosted engine, in order to dismiss the iSCSI storage. So, what're the best guidelines to migrate ? I suspect that simply doing live storage migration will not work :) All backups of the hosted engine are available. Thanks! Matteo

Get Involved with the oVirt Project! Autumn 2016 Edition
by Sandro Bonazzola 30 Sep '16

30 Sep '16

Hi, Have you got some free time? Do you want to get involved in the oVirt project? Do you like the idea of having fresh disk images of your favorite distribution in the oVirt Glance repository? You can help by testing existing online images ensuring they work with cloud-init, or creating one yourself and report your success to devel(a)ovirt.org. We'll be happy to upload the images once these are ready. Do you like Debian? Do you have some programming or packaging skills? Help getting Vdsm running on it! There is some on-going work [14 <https://www.ovirt.org/develop/release-management/features/debian-support-fo…>] on inclusion of Vdsm into Debian. We wish to test and fix Vdsm Debian packages to make them working before the next Debian freeze. You can find all current Debian work (Vdsm and related packages) in Debian git repositories [10 <http://git.debian.org>]. You can follow the progress and participate on oVirt development mailing list [11 <http://lists.ovirt.org/mailman/listinfo/devel>]. Here are some bugs you can try to help with: Bug ID Product oVirt Team Summary 1159784 ovirt-engine Docs [RFE] Document when and where new features are available when upgrading cluster / datacenters 1115059 ovirt-engine Network Incomplete error message when adding VNIC profile to running VM 1237132 ovirt-engine Integration [TEXT] New package listing of engine-setup when upgrading packages is not user friendly 1120585 ovirt-image-uploader Docs update image uploader documentation 1120586 ovirt-iso-uploader Docs update iso uploader documentation 1120588 ovirt-log-collector Docs update log collector documentation 1227019 ovirt-log-collector Integration Require sos >= 3.3 when available - ovirt sosreport plugin doesn't obfuscate password used in aaa extensions Are you great at packaging software? Do you prefer a distribution which is currently unsupported by oVirt? Do you want to have packages included in your preferred distribution? Help getting oVirt ported there! Fedora: http://lists.ovirt.org/pipermail/devel/2015-September/011426.html CentOS: https://wiki.centos.org/SpecialInterestGroup/Virtualization Gentoo: https://wiki.gentoo.org/wiki/OVirt (GSoC: https://wiki.gentoo.org/wiki/Google_Summer_of_Code/2016/Ideas ) Debian: http://www.ovirt.org/develop/release-management/features/debian-support-for… Archlinux: http://www.ovirt.org/develop/developer-guide/arch-linux/ OpenSUSE: https://build.opensuse.org/project/show/Virtualization:oVirt Do you love DevOps?

Here are some of our open tasks you can help with: https://ovirt-jira.atlassian.net/secure/RapidBoard.jspa?rapidView=6 You can also help by sharing how you use oVirt in your DevOps environment (please use [DevOps] in the subject). You can check out more docs on the DevOps side of oVirt in [12 <http://ovirt-infra-docs.readthedocs.org/en/latest/>][13 <http://www.ovirt.org/develop/infra/infrastructure-documentation/>] Do you want to improve oVirt System Testing[15] and the Lago[16] system running them? We have all the documentation[17] you need to get started! Check it out and run the test suite yourself! You don't have programming skills, not enough time for DevOps, but still want to contribute? Here are some bugs you can take care of, also without writing a line of code: https://bugzilla.redhat.com/buglist.cgi?quicksearch=classification%3Aovirt%… Do you prefer to test things? We have some test cases[5 <http://www.ovirt.org/develop/infra/testing/>] you can try, using nightly snapshots[6 <http://www.ovirt.org/develop/dev-process/install-nightly-snapshot/>]. For 4.1 we're rebasing Fedora support on Fedora 24, you can help by running nightly snapshots[6 <http://www.ovirt.org/develop/dev-process/install-nightly-snapshot/>] on it and reporting issues. Do you want to contribute test cases? Most of the features[7 <http://www.ovirt.org/develop/release-management/features/>] included in oVirt are missing a test case, you're welcome to contribute one! Do you want to contribute artworks? oVirt Live backgrounds and covers, release banners, stickers, ....

Ovirt/Gluster replica 3 distributed-replicated problem
by Davide Ferrari 29 Sep '16

29 Sep '16

Hello maybe this is more glustefs then ovirt related but since OVirt integrates Gluster management and I'm experiencing the problem in an ovirt cluster, I'm writing here. The problem is simple: I have a data domain mappend on a replica 3 arbiter1 Gluster volume with 6 bricks, like this: Status of volume: data_ssd Gluster process TCP Port RDMA Port Online Pid ------------------------------------------------------------------------------ Brick vm01.storage.billy:/gluster/ssd/data/ brick 49153 0 Y 19298 Brick vm02.storage.billy:/gluster/ssd/data/ brick 49153 0 Y 6146 Brick vm03.storage.billy:/gluster/ssd/data/ arbiter_brick 49153 0 Y 6552 Brick vm03.storage.billy:/gluster/ssd/data/ brick 49154 0 Y 6559 Brick vm04.storage.billy:/gluster/ssd/data/ brick 49152 0 Y 6077 Brick vm02.storage.billy:/gluster/ssd/data/ arbiter_brick 49154 0 Y 6153 Self-heal Daemon on localhost N/A N/A Y 30746 Self-heal Daemon on vm01.storage.billy N/A N/A Y 196058 Self-heal Daemon on vm03.storage.billy N/A N/A Y 23205 Self-heal Daemon on vm04.storage.billy N/A N/A Y 8246 Now, I've put in maintenance the vm04 host, from ovirt, ticking the "Stop gluster" checkbox, and Ovirt didn't complain about anything. But when I tried to run a new VM it complained about "storage I/O problem", while the storage data status was always UP. Looking in the gluster logs I can see this: [2016-09-29 11:01:01.556908] I [glusterfsd-mgmt.c:1596:mgmt_getspec_cbk] 0-glusterfs: No change in volfile, continuing [2016-09-29 11:02:28.124151] E [MSGID: 108008] [afr-read-txn.c:89:afr_read_txn_refresh_done] 0-data_ssd-replicate-1: Failing READ on gfid bf5922b7-19f3-4ce3-98df-71e981ecca8d: split-brain observed.

Ansible modules supporting oVirt 4
by Martin Perina 29 Sep '16

29 Sep '16

Hi, we have a great news regarding Ansible modules for oVirt 4 management. As you may have already noticed in [1] and thanks to Ondra's hard work we were able to push following modules into Ansible 2.2: ovirt_auth - manages authentication against oVirt engine instance ovirt_vms - manages VM lifecycle - manages VM's disks and NICs (more advanced disks and NICs management will be provided by specialized modules) ovirt_disks - manages VM's disks and floating disks You can find more details about those modules at [2]. But this is not end of our effort, we are working on other modules that should cover most of functionality provided by oVirt SDK and hopefully will be included in Ansible 2.3 (more info also at [2]). Any feedback on those modules would be very welcome. Regards Martin Perina [1] http://www.ovirt.org/blog/2016/09/manage-ovirt-with-ansible-playbooks/ [2] http://www.ovirt.org/develop/release-management/features/infra/ansible_modu…

oVirt 3.6 and Fedora 24: How to change display resolution?
by Richard Harmonson 29 Sep '16

29 Sep '16

I am unable to change the display for a Fedora 24 Workstation using Gnome 3.20 from its default 1024 x 768. I, also, tried a number of spins but the behavior persist. Installing on a physical desktop does not reproduce the symptom. Installing CentOS 7 does not reproduce the symptom. Under the virtual machine "Applications" it shows: kernel-4.7.4-200.fc24 ovirt-guest-agent-common-1.0.12-3.fc24 xorg-x11-drv-qxl-0.1.4-7.fc24
