So I tried cobbler instead and I had it working in just a couple of hours! I'm further along today than a week of foreman's constant problems. Hooray! Here's where I am at now, if I manually configure a VM in Ovirt I can provision it from Cobbler. Great! What I would like to do is to have an easy way from Ovirt say "Grab this cobbler profile and build me a new VM with this template". In my searches on line, I haven't found anything like that. It seems the closest I'm going to get is to use Koan. However, I've not found great information for using Koan with Ovirt. My attempts so far of installing Koan on the Ovirt Management host and trying to get it to provision have all resulted in Koan trying to build a KVM _on_ the management host; not in Ovirt. Does anyone have any good documentation for setting up Cobbler integration into Ovirt? Or at least getting Koan to work with the two?

Hi, looking at https://translate.zanata.org/iteration/view/ovirt/ovirt-4.2?dswid=-6249 I see Russian translation is the only one under 80% for 4.2. If you have some time and know Russian, it's a good time for contributing translations.

GlusterFS performance questions
by Jayme 16 Oct '17

16 Oct '17

I am currently in the process of researching converting an existing SMB infra to virtual. Ovirt/RHEV is a strong contender and checks off a lot of boxes on our list. GlusterFS is appealing but I am finding it very difficult to find any answers or stats/numbers regarding how well it can perform as backend storage for VMs, especially VMs with medium to high workloads, and possibly some or many in a dev environment where many small files are interacted with very frequently. >From my research on GlusterFS in general some people tend to say that it is not the best performer and it's not the best choice for handling small files. How true is this? I understand that there are many variables such as hardware, drives, proper configuration, internal network etc. but what I'm trying to avoid here is going through the whole process of spendng a lot of money building out an ovirt gluster with a proper SSD glusterFS configuration w/ 10gbe internal network only to find out some day down the road that it cannot meet our I/O needs. Can anyone comment on how I can best determine the performance level to expect from a typical ovrt w/ glusterfs replica 3 arbiter 1 configuration. Or perhaps any use cases with people/companies running a similar setup in production with high VM workloads? Right now I'm leaning toward using a SAN due to the simplicity and predictable performance. Although this will definitely cost a lot more money for something that glusterFS *may* be able to handle. Thanks! James

FOSDEM18 Virt & IaaS Devroom CFP
by Piotr Kliczewski 16 Oct '17

16 Oct '17

On behalf of oVirt and the Xen Project, we are excited to announce that the call for proposals is now open for the Virtualization & IaaS devroom at the upcoming FOSDEM 2018, to be hosted on February 3 and 4, 2017. This year will mark FOSDEM’s 18th anniversary as one of the longest-running free and open source software developer events, attracting thousands of developers and users from all over the world. FOSDEM will be held once again in Brussels, Belgium, on February 3 & 4, 2018. This devroom is a collaborative effort, and is organized by dedicated folks from projects such as OpenStack, Xen Project,, oVirt, QEMU, and Foreman. We would like to invite all those who are involved in these fields to submit your proposals by December 1st, 2017. About the Devroom The Virtualization & IaaS devroom will feature session topics such as open source hypervisors and virtual machine managers such as Xen Project, KVM, bhyve, and VirtualBox, and Infrastructure-as-a-Service projects such as Apache CloudStack, OpenStack, oVirt, QEMU, OpenNebula, and Ganeti. This devroom will host presentations that focus on topics of shared interest, such as KVM; libvirt; shared storage; virtualized networking; cloud security; clustering and high availability; interfacing with multiple hypervisors; hyperconverged deployments; and scaling across hundreds or thousands of servers. Presentations in this devroom will be aimed at developers working on these platforms who are looking to collaborate and improve shared infrastructure or solve common problems. We seek topics that encourage dialog between projects and continued work post-FOSDEM. Important Dates Submission deadline: 01 December 2017 Acceptance notifications: 14 December 2017 Final schedule announcement: 21 December 2017 Devroom: 03 and 04 February 2018 (two days- different rooms) Submit Your Proposal All submissions must be made via the Pentabarf event planning site[1]. If you have not used Pentabarf before, you will need to create an account. If you submitted proposals for FOSDEM in previous years, you can use your existing account. After creating the account, select Create Event to start the submission process. Make sure to select Virtualization and IaaS devroom from the Track list. Please fill out all the required fields, and provide a meaningful abstract and description of your proposed session. Submission Guidelines We expect more proposals than we can possibly accept, so it is vitally important that you submit your proposal on or before the deadline. Late submissions are unlikely to be considered. All presentation slots are 45 minutes, with 35 minutes planned for presentations, and 10 minutes for Q&A. All presentations will be recorded and made available under Creative Commons licenses. In the Submission notes field, please indicate that you agree that your presentation will be licensed under the CC-By-SA-4.0 or CC-By-4.0 license and that you agree to have your presentation recorded. For example: "If my presentation is accepted for FOSDEM, I hereby agree to license all recordings, slides, and other associated materials under the Creative Commons Attribution Share-Alike 4.0 International License. Sincerely, <NAME>." In the Submission notes field, please also confirm that if your talk is accepted, you will be able to attend FOSDEM and deliver your presentation. We will not consider proposals from prospective speakers who are unsure whether they will be able to secure funds for travel and lodging to attend FOSDEM. (Sadly, we are not able to offer travel funding for prospective speakers.) Speaker Mentoring Program As a part of the rising efforts to grow our communities and encourage a diverse and inclusive conference ecosystem, we're happy to announce that we'll be offering mentoring for new speakers. Our mentors can help you with tasks such as reviewing your abstract, reviewing your presentation outline or slides, or practicing your talk with you. You may apply to the mentoring program as a newcomer speaker if you: Never presented before or Presented only lightning talks or Presented full-length talks at small meetups (<50 ppl) Submission Guidelines Mentored presentations will have 25-minute slots, where 20 minutes will include the presentation and 5 minutes will be reserved for questions. The number of newcomer session slots is limited, so we will probably not be able to accept all applications. You must submit your talk and abstract to apply for the mentoring program, our mentors are volunteering their time and will happily provide feedback but won't write your presentation for you! If you are experiencing problems with Pentabarf, the proposal submission interface, or have other questions, you can email our devroom mailing list[2] and we will try to help you. How to Apply In addition to agreeing to video recording and confirming that you can attend FOSDEM in case your session is accepted, please write "speaker mentoring program application" in the "Submission notes" field, and list any prior speaking experience or other relevant information for your application. Call for Mentors Interested in mentoring newcomer speakers? We'd love to have your help! Please email iaas-virt-devroom at lists.fosdem.org with a short speaker biography and any specific fields of expertise (for example, KVM, OpenStack, storage, etc.) so that we can match you with a newcomer speaker from a similar field. Estimated time investment can be as low as a 5-10 hours in total, usually distributed weekly or bi-weekly. Never mentored a newcomer speaker but interested to try? As the mentoring program coordinator, email Brian Proffitt[3] and he will be happy to answer your questions! Code of Conduct Following the release of the updated code of conduct for FOSDEM, we'd like to remind all speakers and attendees that all of the presentations and discussions in our devroom are held under the guidelines set in the CoC and we expect attendees, speakers, and volunteers to follow the CoC at all times. If you submit a proposal and it is accepted, you will be required to confirm that you accept the FOSDEM CoC. If you have any questions about the CoC or wish to have one of the devroom organizers review your presentation slides or any other content for CoC compliance, please email us and we will do our best to assist you. Call for Volunteers We are also looking for volunteers to help run the devroom. We need assistance watching time for the speakers, and helping with video for the devroom. Please contact me, Brian Proffitt, for more information. Questions? If you have any questions about this devroom, please send your questions to our devroom mailing list. You can also subscribe to the list to receive updates about important dates, session announcements, and to connect with other attendees. See you all at FOSDEM!

4.1 to 4.2 upgrade
by Charles Kozler 15 Oct '17

15 Oct '17

hello, What would be the process to go from current 4.1 to 4.2-pre? I have been demoing 4.2 on my own lab environment and the WebUI, for my user base, is entirely more intuitive than the previous My 4.1 is relatively new so there isnt much config done to it, that said, wondering what it would take to update ovirt HE w/ 3 nodes + GlusterFS (not managed via ovirt) to 4.2-pre and what it would like like to move back from a -pre channel to mainline Alternatively, I could wait for 4.2 to go main, do you have an estimated date for that? Thanks!

Configuring ilo4 on hp blade gen 9
by Gianluca Cecchi 15 Oct '17

15 Oct '17

Hello, on 4.1.6 I'm configuring fencing on HP blades Gen9. It seems I'm able to use ilo_ssh as agent and that I have only to set 22 as the port and ssh=1 in options Question: why ssh=1??? the agent is named ilo_ssh.... shouldn't be obvious??? The same form command line I MUST set -x even if I use fence_ilo_ssh command Nevertheless, this way I get successful test Sometimes I don't get the same result if I run from shell eg: fence_ilo_ssh -a ilo_ip -l fenceuser -S /usr/local/bin/my_fence_script.sh -x -o status I get sometimes: Unable to connect/login to fencing device I think it could be some sort of delay timeout. In fence_ilo_ssh I see these kinds of timeouts in help --power-timeout=[seconds] Test X seconds for status change after ON/OFF --shell-timeout=[seconds] Wait X seconds for cmd prompt after issuing command --login-timeout=[seconds] Wait X seconds for cmd prompt after login --power-wait=[seconds] Wait X seconds after issuing ON/OFF --delay=[seconds] Wait X seconds before fencing is started How do they map with gui settings options in case I would use some of them? Also, how do I map the command line option -4, --inet4-only Perhaps inet4_only=1 ? I see that ssh=1,inet4_only=1 works but also ssh=1,inet4_only=1,foo=1 works So it is not a reliable test to verify syntax... All in all do you think it is the best agent for ilo4 based blades? I have made some test with fence_ilo4 but unable to get success... what should I enable on ilo web administration page in this case, if you think the agent would be better for any reason? Thanks, Gianluca

How to change network card configuration under bridge on host?
by Derek Atkins 13 Oct '17

13 Oct '17

Hi, I've got a single host running CentOS 7.3 + Ovirt 4.0.6 with hosted engine. I'm having network issues (see previous email thread) and the next thing I'm going to try is to add a new network card and use that instead of the onboard ethernet on the mobo. However it looks like /etc/sysconfig/network-scripts/ifcfg-* get replaced every time the host restarts. Right now it's configured with: eno1, eno2 -> bond0 -> ovirtmgmt I accomplished this by setting up the bond by hand on the host before I installed the hosted engine, but then ovirt "took control" of the configuration. I want to change this to replace eno1 and eno2 with the two new devices when I add the new card tomorrow. What's the best way to do this? I suppose I can just add the new devices as bond0 slaves pretty easily by creating new ifcfg-xxx files for the new devices (I'm assuming they will be eno3 and eno4) that looks similar to the eno1 and eno2 files. However I'd like to also remove eno1 and eno2 from bond0. Yet I suspect if I change ifcfg-eno1 and ifcfg-eno2 by hand, they will just get replaced at the next reboot by ovirt. How do I convince ovirt to stop overwriting those files? Or how do I tell ovirt about the new configuration?

Issues with Windows 7 VM
by Marc Turner 12 Oct '17

12 Oct '17

Hello, I'm a Systems Administrator at Wolfram Research, and we've been having an issue with a Windows 7 x64 VM. This is a new VM with a newly created Cinder VM image attached to it, which was working without issue last week. Earlier today I performed a Windows update and shutdown the VM. When trying to start it back up, it does nothing but fail with the message "Failed to start VM on host. We have several VM hosts set up, so it will bounce around between a few of them, failing each time before giving up entirely. Myself and another SysAdmin have looked through the logs and have not been able to find any reason as to why this VM won't start. No other VM's are having problems, and Cinder is working correctly. If you would have any idea as to why this is happening, or where we could look to figure out what may be going on, it would be much appreciated. Thank you, Marc Turner Systems Administrator Wolfram Research

Add FC domain failed - but reported as used
by Roberto Nunin 11 Oct '17

11 Oct '17

I've tried to add a second FC data domain to our oVirt remote infra, built with 6 hosts in remote and 4 local, where hosted-engine is running. Currently, we are using 4.0.1.1-1.el7.centos. After FC storage setup (zoning/masking), tried to add the new volume to the remote DC. Process was failing with: 2017-10-11 12:57:31,174 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (default task-5) [bfcbca2] Correlation ID: bfcbca2, Job ID: 0850b9ba-a898-472c-9dbd-3ae4f27b2992, Call Stack: null, Custom Event ID: -1, Message: Failed to attach Storage Domain oVirt_datastore_2_NO to Data Center CompanyDCoVirt4.

All are ok. Another attempt to add the volume to the remote DC, was failing blocking me to chosse the volume ID into the GUI interface, because "the LUN is already part of a Storage DOmain". I think that something is still marking as used the new volume into the host-engine DB, even if it isn't available into the GUI interface. If this could be the reason, how to correctly manage this issue ? (apart update the entire installation, planned :) ) Thanks in advance -- Roberto

Show all tasks: *# vdsClient -s 0 getAllTasksInfofd319af4-d160-48ce-b682-5a908333a5e1 : verb = createVolume id = fd319af4-d160-48ce-b682-5a908333a5e19bbc2bc4-3c73-4814-a785-6ea737904528 : verb = prepareMerge id = 9bbc2bc4-3c73-4814-a785-6ea737904528e70feb21-964d-49d9-9b5a-8e3f70a92db1 : verb = prepareMerge id = e70feb21-964d-49d9-9b5a-8e3f70a92db1cf064461-f0ab-4e44-a68f-b2d58fa83a21 : verb = prepareMerge id = cf064461-f0ab-4e44-a68f-b2d58fa83a2185b7cf4e-d658-4785-94f0-391fe9616b41 : verb = prepareMerge id = 85b7cf4e-d658-4785-94f0-391fe9616b417416627a-fe50-4353-b129-e01bba066a66 : verb = prepareMerge id = 7416627a-fe50-4353-b129-e01bba066a66* 2.

Then I tried to add in Foreman.

Yet there it is! Well after poking at it for a while, I realized that the cert Foreman was auto-resolving was still the /OLD/ cert! Step #2 in those ovirt directions says to break the symbolic link to /etc/pki/ovirt-engine/ca.pem. But it doesn't say what to do with that file. So I replaced it with my cert. Restarted ovirt and now Foreman resolves the correct X509 cert! (I have no idea if that broke something else.) But I still get the error in foreman. :-( I feel like I'm still missing something in the ovirt configs. Something needs to be updated/replaced in ovirt that isn't in those docs. Can anyone help me out please? I've been trying for hours and not making progress.

[ANN] oVirt 4.1.7 Third Release Candidate is now available
by Sandro Bonazzola 11 Oct '17

11 Oct '17

The oVirt Project is pleased to announce the availability of the Third Release Candidate of oVirt 4.1.7, as of October 11th, 2017 This update is the seventh in a series of stabilization updates to the 4.1 series. Starting from 4.1.5 oVirt supports libgfapi [5]. Using libgfapi provides a real performance boost for ovirt when using GlusterFS . Due to a known issue [6], using this will break live storage migration. This is expected to be fixed soon. If you do not use live storage migration you can give it a try. Use [7] for more details on how to enable it. This release is available now for: * Red Hat Enterprise Linux 7.4 or later * CentOS Linux (or similar) 7.4 or later This release supports Hypervisor Hosts running: * Red Hat Enterprise Linux 7.4 or later * CentOS Linux (or similar) 7.4 or later * oVirt Node 4.1 See the release notes draft [3] for installation / upgrade instructions and a list of new features and bugs fixed. Notes: - oVirt Appliance is already available - oVirt Live is already available[4] - oVirt Node is already available[4] Additional Resources: * Read more about the oVirt 4.1.7 release highlights: http://www.ovirt.org/release/4.1.7/ * Get more oVirt Project updates on Twitter: https://twitter.com/ovirt * Check out the latest project news on the oVirt blog: http://www.ovirt.org/blog/ [1] https://www.ovirt.org/community/ [2] https://bugzilla.redhat.com/enter_bug.cgi?classification=oVirt [3] http://www.ovirt.org/release/4.1.7/ [4] http://resources.ovirt.org/pub/ovirt-4.1-pre/iso/ [5] http://staged-gluster-docs.readthedocs.io/en/release3.7.0beta1/Features/lib… [6] https://bugzilla.redhat.com/show_bug.cgi?id=1306562 [7] http://www.ovirt.org/develop/release-management/features/storage/glusterfs-… -- SANDRO BONAZZOLA ASSOCIATE MANAGER, SOFTWARE ENGINEERING, EMEA ENG VIRTUALIZATION R&D Red Hat EMEA <https://www.redhat.com/> <https://red.ht/sig> TRIED.
