Get Involved with the oVirt Project! Autumn 2016 Edition
by Sandro Bonazzola 29 Sep '16

29 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? You count stable builds in jenkins ci while trying to fall asleep? Then oVirt infra team is looking for you! Join the infra team and dive in to do the newest and coolest devops tools today! 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, .... Take a look at Fedora Artworks[9 <https://fedoraproject.org/wiki/Artwork#Resources>] as an example of what you can do Do you love alternative architectures? You can test ppc64le and aarch64 packages from CentOS Virt SIG: - https://cbs.centos.org/repos/virt7-ovirt-40-release/ppc64le/ - https://cbs.centos.org/repos/virt7-ovirt-40-release/aarch64/ Is this the first time you try to contribute to the oVirt project? You can start from here [1 <http://www.ovirt.org/develop/>][2 <http://www.ovirt.org/develop/dev-process/working-with-gerrit/>]! You don't know gerrit very well? You can find some more docs here [3 <https://gerrit-review.googlesource.com/Documentation>]. Any other question about development? Feel free to ask on devel(a)ovirt.org or on irc channel[4]. You don't really have time / skills for any development / documentation / testing related task? Spread the word[8 <http://www.zdnet.com/article/how-much-longer-can-red-hats-ovirt-remain-cove…> ]! Let us know you're getting involved, present yourself and tell us what you're going to do, you'll be welcome!

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.

[Input/output error] Now, how is it possible to have a split brain if I stopped just ONE server which had just ONE of six bricks, and it was cleanly shut down with maintenance mode from ovirt? I created the volume originally this way: # gluster volume create data_ssd replica 3 arbiter 1 vm01.storage.billy:/gluster/ssd/data/brick vm02.storage.billy:/gluster/ssd/data/brick vm03.storage.billy:/gluster/ssd/data/arbiter_brick vm03.storage.billy:/gluster/ssd/data/brick vm04.storage.billy:/gluster/ssd/data/brick vm02.storage.billy:/gluster/ssd/data/arbiter_brick # gluster volume set data_ssd group virt # gluster volume set data_ssd storage.owner-uid 36 && gluster volume set data_ssd storage.owner-gid 36 # gluster volume start data_ssd -- Davide Ferrari Senior Systems Engineer

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

oVirt 4.0.x - hosted-engine was not starting properly
by Gervais de Montbrun 29 Sep '16

29 Sep '16

--Apple-Mail=_36EF5248-AA3D-484E-8A71-55F0C8DF8023 Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset=us-ascii Hey All, Since updating to 4.0.x of oVirt, I have had an issue with my hosted = engine. After a some poking around, I think I have figured out my issue = and thought I would share to see what others think. The issue has existed with 4.0, 4.0.1, 4.0.2, 4.0.3, and still exists in = 4.0.4. Description: When my hosted engine starts it reports that it is in a degraded state = with 7 or 8 services still not started when I run systemctl status. It = takes about 6 or 7 minutes to eventually start all the services and come = online. If I don't set my cluster to Global-Maintenance mode it = eventually thinks that my hosted-engine needs to be rebooted and = restarts it before it can start everything. Solution: I realized that Apache was the culprit and found that the proxy to the = ovirt-engine in /etc/httpd/conf.d/z-ovirt-engine-proxy.conf has a super = long timeout with many retries. I changed the settings and now = everything works for me. -> Before change: <LocationMatch = ^/(ovirt-engine($|/)|api($|/)|RHEVManagerWeb/|OvirtEngineWeb/|ca.crt$|engi= ne.ssh.key.txt$|rhevm.ssh.key.txt$)> ProxyPassMatch ajp://127.0.0.1:8702 timeout=3D3600 retry=3D5 <IfModule deflate_module> AddOutputFilterByType DEFLATE text/javascript text/css = text/html text/xml text/json application/xml application/json = application/x-yaml </IfModule> </LocationMatch> -> After change: <LocationMatch ^/ovirt-engine($|/)> ProxyPassMatch ajp://127.0.0.1:8702 timeout=3D5 retry=3D2 <IfModule deflate_module> AddOutputFilterByType DEFLATE text/javascript text/css = text/html text/xml text/json application/xml application/json = application/x-yaml </IfModule> </LocationMatch> If I read the timeout settings correctly, it will wait 60 minutes with 5 = retries. 5 hours is way too long for my little server to hold onto all = those apache processes. The change I made allows for there to be an = error, and also releases apache's hold on the process. Once everything = is ready, apache is ready to serve requests and everything/everyone is = happy. Before making the change, I just get a whitescreen in my browser = and then nothing works until I restart Apache (or I end up in an endless = loop of ovirt-ha services restarting my hosted-engine. I noticed that this setting reverts to the original setting, so oVirt = must be writing this file. Perhaps these number can be changed in oVirt? = If not, I will just setup and ansible play to revert the settings with = working values and restart apache on my engine. :-) Cheers, Gervais --Apple-Mail=_36EF5248-AA3D-484E-8A71-55F0C8DF8023 Content-Transfer-Encoding: quoted-printable Content-Type: text/html; charset=us-ascii <html><head><meta http-equiv=3D"Content-Type" content=3D"text/html = charset=3Dus-ascii"></head><body style=3D"word-wrap: break-word; = -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" = class=3D"">Hey All,<div class=3D""><br class=3D""></div><div = class=3D"">Since updating to 4.0.x of oVirt, I have had an issue with my = hosted engine.

vioscsi.sys BSOD with Win 7
by Cam Mac 29 Sep '16

29 Sep '16

Hi, I'm running oVirt 3.6.3.4-1.el7.centos and when I install a Win 7 guest VM, using VirtIO disk, networking etc, it goes through the install process ok, but blue screens upon boot with a vioscsi.sys error (attached). I have tried the official version ovirt-guest-tools-iso 3.6.0 0.2_master.fc22, as well as some earlier and later versions. I am using a PXE boot method with a Windows deployment server, which has the drivers from the oVirt tools ISO installed (indeed, it picks up the drive and networking and I can see it installing the drivers). I have tried with the generic IDE and rtl8139 config on the guest, and it also fails with the same vioscsi.sys error after rebooting upon finishing installation even though I'm using IDE as the disk driver. I have uploaded a win 7 x64 ISO and tried installing that, and it loads the VirtIO viostor driver (using the method at: https://www.ovirt.org/documentation/how-to/virtual-machines/create-a-window…) and even manages to partition the disks, but fails to install on the disk (screenshot attached). I've tried temporarily removing the vioscsi files from the install server as a last resort, but as expected it fails to install properly, though I thought it used the viostor driver instead. Thanks for any help. Regards, Cam

Windows VDI Licensing
by Maxence Sartiaux 29 Sep '16

29 Sep '16

Hello, I currently work on a Windows VDI infrastructure based on ovirt, i'm looking for informations or experiences about Windows/Office VDI Licensing. My pool is stateless and the domain controller is a Samba 4.5. I called Microsoft for informations they told me i need a Windows Server Active Directory because it's impossible to activate the Windows with a Samba 4 AD. Can someone confirm ? If it's possible with a Samba AD, what license do i need for Windows and for Office ? I don't know which one is better, SA / VDA / RDS CAL / ... Thank you.

Replacing Certificates in hosted-engine cluster
by Joshua Doll 29 Sep '16

29 Sep '16

Hi, I have a two node cluster running a hosted-engine setup. I have stood up an enterprise CA and would like to replace the ovirt self signed certificates. I can't find a list of all the certificates online. Is there a list, or can someone point me in the right direction? Thanks, Josh
