UPS with USB Support
by florentl 30 Nov '18

30 Nov '18

Hi everybody, I'm currently setting up an ovirt solution. I have three servers with glusterfs. They run hosted engine. I configured the power management of the node for using idrac agent (I have Dell servers). The communication is ok but I don't really know if configuring power management is very usefull with only three servers. My three servers are powered via an ups which have only one usb port. I'm wondering what is the best option to shutdown the datacenter in case of power failure. I have read in previous posts that I have to write a script. So I think I'm going to : - install apcupsd on the node connected with the ups via usb - configure apcupsd.conf to lanch a script and send a mail - write a script to shutdown properly all the wm and to put the datacenter in maintenance mode What do you think about this solution ? Is there a better way to manage the vm's and datacenter's shutdown with the power management solution associated with ovirt host ? Regards, Florent

oVirt Node on CentOS 7.5 and AMD EPYC Support
by Tobias Scheinert 30 Nov '18

30 Nov '18

Hi, I am currently building a new virtualization cluster with oVirt, using AMD EPYC processors (AMD EPYC 7351P). At the moment I'm running oVirt Node Version 4.2.3 @ CentOS 7.4.1708. We have the situation that the processor type is recognized as "AMD Opteron G3". With this type of instruction set the VMs are not able to do AES in hardware, this results in poor performance in our case. I found some information that tells me that this problem should be solved with CentOS 7.5 --> <https://access.redhat.com/errata/RHEA-2018:1488> My actual questions: - Are there any further information about the AMD EPYC support? - Any information about an update of the oVirt node to CentOS 7.5? Greeting Tobias

About Windows guest agent
by Jingjie Jiang 29 Nov '18

29 Nov '18

Hi, I am new in oVirt and I'd like to get the clarification about the packages which support the function of Window guest agent from 4.2 release and how to build it. I looked through the document from ovirt.org, such as https://www.ovirt.org/documentation/internal/guest-agent/guest-agent-for-wi… It mentioned: /With the release of oVirt 3.5 we have introduced the oVirt WGT (Windows Guest Tools)./ // /The oVirt WGT provides an ISO with all the tools and drivers one needs to install on a Windows VM, with an easy to use installer to install it all in one step./ // /So manual compilation and installation of oVirt Guest Agent is no longer necessary./ // /The oVirt WGT ISO is included in //ovirt-guest-tools-iso-3.5-7.noarch.rpm <http://resources.ovirt.org/pub/ovirt-3.5/rpm/fc20/noarch/ovirt-guest-tools-…>//package./ Now, ovirt-guest-tools-iso is up to 4.2.4. I found the src rpm from https://resources.ovirt.org/pub/ovirt-4.2/rpm/el7/SRPMS/ovirt-guest-tools-i…, but I could not find ovirt-guest-tools-iso from github, only found ovirt-wgt. After clone the ovirt-wgt, I got the SPICE-tools-0.141.iso built. My question is : 1. Is ovirt-wgt used for Windows guest? 2. If so, how can I build ovirt-guest-tools-iso package or ovirt-tools-setup.iso Thanks, Jingjie // //

problems with aaa auth
by cmcl＠dneg.com 29 Nov '18

29 Nov '18

Hi, We've got problems authenticating using ldap accounts on the admin/vm portal. It reports: "Unable to log in. Verify your login information or contact the system administrator." We're running RHEV version 4.2.4.5-0.1.el7_3. I've tested ovirt-engine-extensions-tool using 'aaa login-user' with my profile name and a username and it auths fine. I can't find any log that might give a hint as to why it is failing. The ui.log is empty. It is also extremely slow (it spends a lot of time "waiting for cache..." just to load the administration portal, as well as to log in. Thanks for any help, Cam

AMD Threadripper support
by Darin Schmidt 29 Nov '18

29 Nov '18

My Issue is that there isnt an option to select anything other than Opteron based AMD chips. Is there a way to add my CPU to the list? I have an AMD 2970wx Threadripper. I found an article stating that you can edit the postre database. But where do I find the info needed to add a CPU to the list? Also when I tried to follow the instructions, I get: -bash-4.2$ /opt/rh/rh-postgresql95/root/bin/psql -h localhost -p 5432 -U engine -W /opt/rh/rh-postgresql95/root/bin/psql: error while loading shared libraries: libpq.so.rh-postgresql95-5: cannot open shared object file: No such file or directory

renewing 3rd-party certificate
by p.staniforth＠leedsbeckett.ac.uk 29 Nov '18

29 Nov '18

Hello, our system was using a certificate from a third-party CA that needed to be renewed. I created a CSR from the certificate and key, I replaced the certificate with the new one ( I also had to replace the CA certificate-chain). restarted the apache server but could no longer authenticate to our AD. I ran engine-setup, restarted the engine and also reinstalled the ROOTCA of our AD in the keystore. I got the system running but is there a documented procedure for updating 3rd-party certificates when authenticating to AD. Thanks, Paul S.

RAID L1/L5/L10 + NFS Loopback Benchmarks
by Andrei Verovski 28 Nov '18

28 Nov '18

Hi ! I run a series of benchmarks with IOZONE testing performance of different RAID configurations on HP ProLiant DL380 + impact of NFS loopback. NFS loopback is necessary even for very small systems (e.g. just 2 nodes), since oVirt local storage setup is limited to single (only one) node per data center and this is quite useless from the point of view of functionality. Full article: http://www.vacuum-tube.eu/wp/?p=537 Short YouTube slide show: https://www.youtube.com/watch?v=Xw_VN9G8jSI Related video: Moving away from local storage setup to NFS/GlusterFS https://www.youtube.com/watch?v=2ebhZ5U6x_Y

Re: AffinityGroup API
by Ondra Machacek 28 Nov '18

28 Nov '18

Can you please share the script? And also what's the permission of the user you are executing the script. When see error 'User is not authorized to perform the action', we print in engine.log, what's exactly wrong meaning we print what permissions the user is missing in order to execute that action. So it may help you find out what's wrong as well.

vGPU not available in "type mdev"
by Marc Le Grand 27 Nov '18

27 Nov '18

Hello I followed the tutorial regarding vGPU but it's not working, i i guess it's a Nvidia licence issue, but i need to be sure. My node is installed using the node ISO image. I just removed the nouveau driver ans installed the nVidia one. My product is : "GK106GL [Quadro K4000]" My driver is : NVIDIA-Linux-x86_64-390.87 In the host peripherals I see my card (pci_0000_05_00_0) listed, but the column "type mdev" is empty, as the doc says I should see vGPU i guess something is missing. I took a look, there seems to be nVidia vGPU copatible driver, but no trace of it. The only vGPU stuff i found it's "NVIDIA VIRTUAL GPU" and i understand I have to pay to use vGPU on my nVidia card. is this correct or no ? If i'm supposed to pay is there a free workaround ? thanks for your help marc

Remote console access for old Ovirt 3.6 install
by David Gossage 27 Nov '18

27 Nov '18

I have an older 3.6.7 setup I am still using at a location. The hosted-engine is up but not responding {"reason": "failed liveliness check", "health": "bad", "vm": "up", "detail": "up"} I am guessing it got into some paused or halted state after a power outage and storage went offline for a short bit and I may need to manually perform some tasks. When I attempt the suggested method of hosted-engine --set-maintenance --mode=global hosted-engine --console I get an error about Use the password you've set using --add-console-password for logging in ** (remote-viewer:11479): WARNING **: Could not open X display Cannot open display: Run 'remote-viewer --help' to see a full list of available command line options Their are 7 other VM's running I was able to manually continue from vdsClient Is their a way to get remote access to this engine? *David Gossage* *Carousel Checks Inc. | System Administrator* *Office* 708.613.2284

Upgrade 4.0 to 4.1: Global Maintenance Mode not recognized
by gregor 27 Nov '18

27 Nov '18

Hello, I upgraded one host from 4.0 to 4.1 without problems. Now I have a problem with another host, in another network, where the Global Maintenance mode is not recognized by engine-setup. Is there a way to force the setup or set the maintenance mode inside the database? One problem can be that an the host was accidentally upgraded to 4.1 before I upgraded the engine. kind regards gregor

oVirt impersonation and sessions
by Anastasiya Ruzhanskaya 26 Nov '18

26 Nov '18

Hello everyone! I wanted to find out how the impersonation technique used in oVirt works? I know from libvirt developers, that oVirt opens one connection only for multiple clients. How does this work? Also I found out in source code that in ActionParameterBase class the sessionId field is marked transient but, for example, for GWT rpc message, which goes to the server and says what action will be made (shut down, pause vm) this is the only field in all sent information which says what the session is. Where is the session sent instead? There was also a field with session id in https headers, but this was related to cookie so I am not completely sure if this can help to identify the current user.

How to kill hanged task listed in engine but not in vdsm-client?

However, I can't kill task from the hosts itself since vdsm-client returns zero task on any host: # vdsm-client Host getAllTasksInfo {} How can I deal with it? I already tried to restart ovirt-engine.service but task is still there and prevent me to put the involved storage domain into maintenance. I also tried the "clear" method for service "job" via RestAPI but it fails since it's not an external job. Thank you, -- Stefano Stagnaro Prisma Telecom Testing S.r.l.

IPA Users via AD DC's
by TomK 26 Nov '18

26 Nov '18

Hello, I've configured LDAP via IPA in oVirt 4.X. It works for locally defined users in IPA but not those mapped from the AD DC. So I had two questions: 1) Is there a format of the username and password I need to type in for this to work? Or is retrieving AD DC mapped users not possible with oVirt right now? 2) Can I use two providers in oVirt simultaneously? One IPA and the other AD? -- Cheers, Tom K. ------------------------------------------------------------------------------------- Living on earth is expensive, but it includes a free trip around the sun.

VM has snapshots with disks in illegal status
by Markus Schaufler 26 Nov '18

26 Nov '18

Hi! I've testet a backup solution which turned out to work not as expected. It left some VM's turned off which cannot be restarted. When trying to delete the snapshot(s) of the vms following error message occurs: "Cannot remove Snapshot. The following attached disks are in ILLEGAL status: System, Disk2 - please remove them and try again" Also I cannot detach any disk because of: Cannot remove Snapshot. The following attached disks are in ILLEGAL status: System, SRV_Metrics-Store_Disk1 - please remove them and try again. I already tried via "unlock_entity" script to remove either the snapshots or the disks (after backing them up) and via CLI but without success (same error message). Any idea on that?

NFS storage and importation
by AG 26 Nov '18

26 Nov '18

Hello, Our cluster use NFS storage (on each node as data, and on a NAS for export) We currently have a huge problem on our cluster, and export VM as OVA takes lot's of time. I checked on the NFS storage, and it looks like there's files who might be OVA in the images directory, and OVF files in the the master/vms Can someone tell me if, when i install a new engine, there's a way to get this VMs back inside the new engine (like the import tools by example) Thank you a lot for your answers, Regards, Alexis ps : it should be said in the documentation to NEVER use backup of an engine when he is in a NFS storage domain on a node. It looks like it's working, but all the data are unsynch with reality.

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
