Re: Cannot enable maintenance mode
by Lukas Svaty 16 Oct '19

Did you "Consider manual intervention" such as "stopping" or "migrating Vms" which are running on that host? If you are trying to put host to maintenance, it will migrate all the VMs somewhere else, thus... you might have problem with migrations (try to migrate them to other destination host) or power them off.

Clarifications on support@
by Marc Dequènes (Duck) 16 Oct '19

16 Oct '19

Quack, We do as a community provide help on the MLs and reply to JIRA tickets but there is no customer support as it is not a product but a community project. Historically, probably for some other purpose, support@ was created, but noone remembers why. Anyway, the alias redirected to postmaster so it was not very useful. There was also a ML which could not receive mails because of the alias but probably got noticed in the new ML UI when we migrated. Recently more people subscribed and posted requests using the UI. After discussing with the infra team, and to avoid confusion and unreplied requests on this channel, we decided to remove it. I thus unsubscribed people from the list so that they would notice it and then purged the list and alias. Regards. \_o<

Hi Sir/Madaam, I'm trying to search for hours now but still no luck I can already access the oVirt engine web port via IP address. I'm running via Virtualbox machine. Configured data center, cluster. Then after adding new host. Error occur "Install failed". Tried to check the engine log. It says "EVENT ID: VDS INSTALL_FAILED(505), Host ovirt host installation failed. Command returned failure code 1 during SSH session" My IP address and password is exact. And edited the /etc/host IP_ADDRESS localhost.localdomain My hostname is default, BTW Any help what's wrong with the configuration.

Clean up engine database?
by Chris Adams 14 Oct '19

14 Oct '19

On my oVirt 4.1.9 cluster, the hosted engine filled up its disk last night (it was deployed from the engine appliance image and had a 20G root and 5G swap). I gained a little space by trimming down swap, but I need to clean it up. It looks like the problem is the Postgres database - /var/lib/pgsql/data is using 16G. Is there some cleanup I can do (and then some way to keep it from happening again)? Also, is there a way to extend the hosted engine disk? It's on iSCSI storage, and the LUN has free space. -- Chris Adams <cma(a)cmadams.net>

Bridge issue
by con_louca＠hotmail.com 14 Oct '19

14 Oct '19

Hello all, I am trying to setup a bridge. I have 3 virtual machines. The 1st acting as router, the second acting as bridge and the 3rd is the client, like the following diagram ROUTER BRIDGE CLIENT internet(ovirtmng network) ----- [eth0 router --eth1 ] -------[eth0 --[br0]-- eth1] -------[--eth Windows 10] The problem is that windows 10 is not able to connect the internet although is able to allocate ip. I use ovirt external network to connect the VMs to each other. It seems that Windows 10 sends ARP to BRIDGE, the BRIDGE sends the ARP to ROUTER but the replies are not passing the br0 when it comes a reply from ROUTER to Windows 10. I use oVirt 4.3.6. Do you know what should be the issue ? Is there a chance that ovirt blocking the bridge? Thanks

New Certificate -> Image-IO-Proxy Errors
by Markus Schaufler 14 Oct '19

14 Oct '19

Hi, I've changed the cert to an official cert using the howto at https://www.ovirt.org/documentation/admin-guide/appe-oVirt_and_SSL.html Got two problems/questions now: 1. The image-io-proxy doesn't work now 2. I tried to upload an ISO image, which is stuck and locked now @1: Which logs should I watch and are there any troubleshooting tips at front? @2: I've already tried the "unlock_entity.sh" script, which didn't help. So I tried to login to the CLI to have a look, if there's some kind of "upload" job still active - but there's no more CLI. How can I check actual running or stuck jobs? Many thanks in advance

Import OVA Error - HE version Version 4.3.5.4-1.el7
by paul.christian.suba＠cevalogistics.com 14 Oct '19

14 Oct '19

Hi, We have 2 oVirt Lab environments. Trying to copy the VM templates or OVA files to Lab2 from Lab1. I have copied the ovas in the NFS share of LAB1 to the NFS ISO Domain of Lab2. The NFS ISO Domain of Lab2 can be seen mounted on all hosts via df -h. If I do a template import with OVA as source and the /rhev/data-center/mnt/XX_XX defined path of the ISP domain, I either get nothing or an error. I get nothing if I do not include the file name. If i include the file name, i get "Uncaught exception occurred. Please try reloading the page. Details: (TYpeError): Cannot read property 'ob' of null. Please have your administrator check the UI logs" I created an NFS ExportDomain in lab2. Copied the files again from the NFS appliance. Did a repeat of the steps, but selected export domain. Same results.

Change self-hosted engine storage domain
by Strahil 12 Oct '19

12 Oct '19

Hello All, Recently I wanted to enable nested virtualization on my cluster and thus I had to redeploy the first host. Sadly, some time ago I have taken the shortcut and changed the values in /etc/ovirt-hosted-engine/hosted-engine.conf locally in order to replace the gluster host and mount options. Thus, after the redeploy, I had to restore the old config in order to be able to mount the shared storage. Now I want to make the proper changes and according to an old thread I need to run the following commands , but they fail. Can some one advise what is the correct syntax ? [root@ovirt1 ~]# hosted-engine --set-shared-config storage gluster1:/engine Duplicate key storage, please specify the key type. Available types are: ['he_local', 'he_shared'] [root@ovirt1 ~]# hosted-engine --set-shared-config mnt_options backup-volfile-servers=gluster2:ovirt3 Duplicate key mnt_options, please specify the key type. Available types are: ['he_local', 'he_shared'] Best Regards, Strahil Nikolov

Move Hosted Engine to external oVirt or VMware
by Markus Schaufler 11 Oct '19

11 Oct '19

Hi, I've got a oVirt Infrastructure with 4 nodes and a self-hosted engine. The hosted engine also manages additional 4 nodes in 4 datacenters. Two tasks: - Re installation of our infrastructure without interfering or interrupting the external nodes. - Separate the external hosts from our infrastructure by either leaving them in the old hosted engine or setting up a new hosted engine on VMware or the new Ovirt Infrastructure We've already drained 2 of our 4 nodes, re-installed them with ovirt node and a new self-hosted engine and moved our VMs onto it. On the two remaining nodes only runs the old self-hosted engine which still manages the 4 external hosts - which prevents me from reinstalling that remaining hosts. I'd prefer to move the old HE to the new oVirt Installation or to our VMware infrastructure. Is that possible and what pitfalls do I have to care of? Many thanks for any hint on this! Markus

FOSDEM 2020 Virtualization & IaaS Devroom CfP
by Piotr Kliczewski 11 Oct '19

11 Oct '19

We are excited to announce that the call for proposals is now open for the Virtualization & IaaS devroom at the upcoming FOSDEM 2020, to be hosted on February 1st 2020. This year will mark FOSDEM’s 20th 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 1st & 2nd, 2020. 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, 2019. 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: 10 December 2019 Final schedule announcement: 15th December 2019 Devroom: 1st February 2020 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.) 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. 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 devroom mailing list [2] 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!

Bridge Issue
by Constantinos L 11 Oct '19

11 Oct '19

Hello all, I am trying to setup a bridge. I have 3 virtual machines. The 1st acting as router, the second acting as bridge and the 3rd is the client, like the following diagram ROUTER BRIDGE CLIENT internet(ovirtmng network) ----- [eth0 router --eth1 ] -------[eth0 --[br0]-- eth1] -------[--eth Windows 10] The problem is that windows 10 is not able to connect the internet although is able to allocate ip. I use ovirt external network to connect the VMs to each other. It seems that Windows 10 sends ARP to BRIDGE, the BRIDGE sends the ARP to ROUTER but the replies are not passing the br0 when it comes a reply from ROUTER to Windows 10. I use oVirt 4.3.6. Do you know what should be the issue ? Is there a chance that ovirt blocking the bridge?

Re: owner of vm paused/unpaused operation

You can always check the queue_if_no_path multipath.conf option and give it a try. But if your system that is queue-ing get's rebooted - that will be data loss -> use on your own risk. Don't forget that the higher in I/O chain you go - the higher the timeout is needed, so your VM should also use multipath with that option, in addition to the host. Still, we can't help you if you use that feature and you loose data.

iSCSI storage domain with no switch
by MIMMIK _ 10 Oct '19

10 Oct '19

Is it possibile to have a storage domain on an iSCSI LUN if the storage is connected to the cluster physical nodes with no switch and only direct connections? This is the scenario: - we have two physical nodes with 2 iSCSI ports each. - the storage has 2 controllers, 2 iSCSI ports on each controller - each server is directly connected with a port to a storage port on a controller and to another storage port on the other controller. Do you think is this possibile, maybe using any trick or workaround? Thanks. Regards

owner of vm paused/unpaused operation
by Gianluca Cecchi 10 Oct '19

10 Oct '19

Hello, I'm doing some tests related to storage latency or problems manually created to debug and manage reactions of hosts and VMs. What is the subsystem/process/daemon responsible to pause a VM when problems arise on storage for the host where the VM is running? How is determined the timeout to use to put the VM in pause mode? Sometimes I see after clearing the problems that the VM is automatically un-paused, sometimes no: how is this managed? Are there any counters so that if VM has been paused and and problems are not solved in a certain timeframe the unpause can be done only manually by the sysadmin? Thanks in advance, Gianluca
