Hi, i'm new to Ovirt. Can i create qcow2 images with l2-cache-size parameter? Qemu supports it, see http://blogs.igalia.com/berto/2015/12/17/improving-disk-io-performance-in-q… But i'm not sure if the Ovirt frontend can handle it? thanks, Kai

Best way to add qcow2 file to block storage domain
by Gianluca Cecchi 22 Nov '18

22 Nov '18

Hello, I have a qcow2 image file with these details with "qemu-img info" command: file format: qcow2 virtual size: 66G (70866960384 bytes) disk size: 1.5G cluster_size: 65536 Format specific information: compat: 0.10 I'm on 4.2.6 and If I try to upload as a disk from the GUI it seems it tries to upload full 66Gb, not 1.5Gb... And it goes paused after the probably transferred 1.5Gb... Also, I would like it to be qcow2 1.1 and not 0.10 I have run: qemu-img convert -O qcow2 -o compat=1.1 source.qc2 source.qc2_v3 and now I have file format: qcow2 virtual size: 66G (70866960384 bytes) disk size: 4.2G cluster_size: 65536 Format specific information: compat: 1.1 lazy refcounts: false refcount bits: 16 corrupt: false Is it expected to pass from 1.5Gb to 4.2Gb after conversion? Anyway also in 1.1 format, if I try to upload It keeps sending the whole 66Gb and now it goes in paused after about 1 minute (at rate of 60MB/s) that lets me think that once arrived at the 4.2Gb size it has problems... Any hint? Thanks, Gianluca

FOSDEM‘19 Virtualization & IaaS Devroom CfP
by Piotr Kliczewski 22 Nov '18

22 Nov '18

We are excited to announce that the call for proposals is now open for the Virtualization & IaaS devroom at the upcoming FOSDEM 2019, to be hosted on February 2nd 2019. This year will mark FOSDEM’s 19th 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 2nd & 3rd, 2019. This devroom is a collaborative effort, and is organized by dedicated folks from projects such as OpenStack, Xen Project, oVirt, QEMU, KVM, and Foreman. We would like to invite all those who are involved in these fields to submit your proposals by December 1st, 2018. 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 KubeVirt, Apache CloudStack, OpenStack, oVirt, QEMU and OpenNebula. 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: 1 December 2019 Acceptance notifications: 14 December 2019 Final schedule announcement: 21 December 2019 Devroom: 2nd February 2019 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 30 minutes, with 20 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 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!

how to edit a floating disk
by Gianluca Cecchi 22 Nov '18

22 Nov '18

Hello, sometimes I need to modify a not assigned disk, eg change description, change alias or extend in size. Nowadays I do it through temporary assignment to a VM from where I can "edit" the disk. Instead in Storage --> Disks or Storage --> Domains --> Domain Name --> Disks I cannot do it Is it intended by design? Do you think it could be useful to be able to edit in some way also in these two modes and not only when attached to a VM? Gianluca

OVF update failure? Export domain.
by Jacob Green 21 Nov '18

21 Nov '18

So, I found this bug report Bug 1554116 <https://bugzilla.redhat.com/show_bug.cgi?id=1554116#c1>, and it looks like it was squashed(fixed) in ovirt 4.2.2. I am running 4.2.6 and yesterday when I was placing our export domain in maintenance and detaching, I saw this message about ignoring OVF update failure. I was able to Detach and Reattach the export Domain without any problems. But I wanted to know if this is normal or not? I did not check the box on either occasion. Thank you -- Jacob Green Systems Admin American Alloy Steel 713-300-5690
