User cannot create VMs having sufficient permissions to do so
by nicolas＠devels.es 18 Oct '17

18 Oct '17

Hi, We're running ovirt-4.1.6.2-1. We have a user that logs into the user portal and tries to create a VM, but a message claiming that "There is no Cluster on which you can create a VM. Please check Data Center status and Cluster permissions." shows up. However, this user has permissions on the cluster (both VmCreator and DiskProfileUser, and also has a Quota created on the Cluster which allows him to create VMs). When clicking on the 'New VM' button, all we see in the engine.log is: 2017-10-18 10:59:31,825+01 ERROR [org.ovirt.engine.core.bll.GetAllLabelsQuery] (default task-103) [c23549c6-37a4-48d7-923d-6618e027cdca] Query execution failed due to insufficient permissions. This user has pretty much the same permissions as thousands of users who can create VMs, but this one can't. How can we debug what's happening and how to solve it? Thanks.

Hosted Engine storage on management IP
by TranceWorldLogic . 18 Oct '17

18 Oct '17

Hi, I was trying to setup separate gluster network in ovirt. But I saw hosted-storage volume which I had created for hosted-engine still running on managment network. Can I move that hosted-storage gluster volume on gluster network ? Thanks, ~Rohit

Unresponsive instance
by JC Clark 18 Oct '17

18 Oct '17

Dear Team, After a power failure and restart, one of my instances would not display properly from the Ovirt User Portal. This error would scroll down the screen repeatly to infinitum. XFS (dm-0): Metadata CRC error detected at xfs_inobt_read_verify+0x79/0xb0 [xfs], xfs_inobt block 0x1df188 XFS (dm-0): Unmount and run xfs_repair XFS (dm-0): First 64 bytes of corrupted metadata buffer: (Hex Dump) I detached the boot disk and attached to another instance and ran xfs_repair on it, to no avail. The instance boots fine and I am able to access via XRDP. When I try to access via spice or VNC I get the error. Suggestions? Thanks

Ovirt + Cobbler + Koan ?

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!
