The version of ovirt-manager is 4.3.6.7。 I have two ovirt-nodes. After I restart one ovirt-node, all the Linux virtual machines on the ovirt-node can startup. But all the Windows virtual machines on the ovirt-node can't startup。 The title show the error: VM ovirt-win10-01 is down with error. Exit message: Unable to get volume size for domain 5cee5082-074e-4a8b-a750-0e8fb0aff63c volume 05063eec-ca54-42c6-92d6-0a6775545eba. How can I solve this problem ?

Removed FC LUN causes multipath to spam syslog
by Juhani Rautiainen 06 Mar '21

06 Mar '21

Hi! We are running ovirt 4.3.10 and we are migrating from 3PAR to Dell SC. I've managed to transfer disks from one LUN away and removed it (put it in maintenanced, detached it and removed it). Now multipath seems to spam the logs for missing disks. How can I stop this? Mar 5 09:58:58 ovirt01 multipathd: 360002ac00000000000000272000057b9: sdr - tur checker reports path is down Mar 5 09:58:59 ovirt01 multipathd: 360002ac00000000000000272000057b9: sdh - tur checker reports path is down And so on. Any idea how I can quiet this? And why didn't oVirt do this automatically? Thanks, Juhani

Create update and security plan
by Gilson Schmidt 04 Mar '21

04 Mar '21

Hi We have a large hypervisors park, and now we are starting to adopt oVirt. And I need an update and security plan for oVirt Nodes. I need to know: - What is the update cycle for oVirt? - How large companies treat the security of oVirt Node. What is the frequency of updates; Is an additional service enabled / installed on oVirt Node? Is SSH enabled maintained? What is the sysadmin access format? Currently on other hypervisors (Xen) using Vault, or we disable SSH on ESXi. How do large companies configure oVirt to comply with the needs passed on by the Security Team? Tks very much.

Difference between edit cluster and upgrade?
by Gianluca Cecchi 04 Mar '21

04 Mar '21

Hello, supposing I upgrade my env from 4.3 to 4.4. Then I can update my clusters' compatibility from 4.3 to 4.5. I can do it in two ways: 1) select cluster line, "edit" button and change "Compatibility Version" from 4.3 to 4.5 2) select cluster line, "upgrade" button correct? What is the difference? Thanks, Gianluca

[ANN] oVirt 4.4.5 Eighth Release Candidate is now available for testing
by Lev Veyde 04 Mar '21

04 Mar '21

oVirt 4.4.5 Eighth Release Candidate is now available for testing The oVirt Project is pleased to announce the availability of oVirt 4.4.5 Eighth Release Candidate for testing, as of March 4th, 2021. This update is the fifth in a series of stabilization updates to the 4.4 series. How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1 Note: Upgrading from 4.4.2 GA or later should not require re-doing these steps, if already performed while upgrading from 4.4.1 to 4.4.2 GA. These are only required to be done once. Due to Bug 1837864 <https://bugzilla.redhat.com/show_bug.cgi?id=1837864> - Host enter emergency mode after upgrading to latest build If you have your root file system on a multipath device on your hosts you should be aware that after upgrading from 4.4.1 to 4.4.5 you may get your host entering emergency mode. In order to prevent this be sure to upgrade oVirt Engine first, then on your hosts: 1. Remove the current lvm filter while still on 4.4.1, or in emergency mode (if rebooted). 2. Reboot. 3. Upgrade to 4.4.5 (redeploy in case of already being on 4.4.5). 4. Run vdsm-tool config-lvm-filter to confirm there is a new filter in place. 5. Only if not using oVirt Node: - run "dracut --force --add multipath” to rebuild initramfs with the correct filter configuration 6. Reboot. Documentation - If you want to try oVirt as quickly as possible, follow the instructions on the Download <https://ovirt.org/download/> page. - For complete installation, administration, and usage instructions, see the oVirt Documentation <https://ovirt.org/documentation/>. - For upgrading from a previous version, see the oVirt Upgrade Guide <https://ovirt.org/documentation/upgrade_guide/>. - For a general overview of oVirt, see About oVirt <https://ovirt.org/community/about.html>. Important notes before you try it Please note this is a pre-release build. The oVirt Project makes no guarantees as to its suitability or usefulness. This pre-release must not be used in production. Installation instructions For installation instructions and additional information please refer to: https://ovirt.org/documentation/ This release is available now on x86_64 architecture for: * Red Hat Enterprise Linux 8.3 or newer * CentOS Linux (or similar) 8.3 or newer This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: * Red Hat Enterprise Linux 8.3 or newer * CentOS Linux (or similar) 8.3 or newer * oVirt Node 4.4 based on CentOS Linux 8.3 (available for x86_64 only) See the release notes [1] for installation instructions and a list of new features and bugs fixed.

EL7 Host support in 4.4.x
by Vrgotic, Marko 04 Mar '21

Hi oVirt, After reviewing the https://access.redhat.com/articles/973163 I wonder is it possible to have a Host running EL7, in oVirt 4.4 to support ability to still run OSs like Win 2008R2, or is it a hard NO? ----- kind regards/met vriendelijke groeten Marko Vrgotic Sr. System Engineer @ System Administration ActiveVideo o: +31 (35) 6774131 m: +31 (65) 5734174 e: m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com> w: www.activevideo.com<http://www.activevideo.com> ActiveVideo Networks BV.

What happens in loss of network scenarios?
by David White 04 Mar '21

04 Mar '21

I tested oVirt (4.3? I can't remember) last fall on a single host (hyperconverged). Now, I'm getting ready to deploy to a 3 physical node (possibly 4) hyperconverged cluster, and I guess I'll go ahead and go with 4.4. Although Red Hat's recent shift of CentOS 8 to the Stream model, as well as the announcement that RHV is going away makes me nervous. I really don't see any other virtualization software doing quite the same stuff as oVirt at the moment. One of my questions is around the back end out-of-band network for data replication. What happens if all 3 servers are healthy and the normal network is fine for serving traffic to the VM consumers, but the switching network for data replication goes down? Is it possible to configure oVirt to "fail over" to the front-end network?I'm also wondering if its possible to do away with a switch all together, and just link the physical hosts together directly (like a cross-over cable) for the data replication. I'm also wondering what would happen in the following scenario: - All 3 servers are healthy - The out-of-band data replication network is healthy - 1 or 2 of the servers suddenly lost network connectivity on the front-end network What then? Would everything just keep working, and network traffic be forced to go out the healthy interface(s) on the remaining hosts? Sent with ProtonMail Secure Email.

Cloud-init confusion
by Shantur Rathore 04 Mar '21

04 Mar '21

Hi Users, I am new to oVirt and having some confusion with cloud-init. I have a VM which supports Cloud Init and when I enable Cloud Init under Initial boot settings of VM, the cloud-init config disk isn't attached to the VM. If I use Run-Once and enable Cloud-Init the config disk is attached to the VM and works as expected. Is cloud-init only supposed to work with Run-Once or am I missing something? Thanks in advance.

Template backing disks on different storage
by Shantur Rathore 04 Mar '21

04 Mar '21

Hi Users, I am evaluating oVirt coming from a VMware background. I have a test cluster with 6 machines running oVirt Node providing compute + gluster services. There are 2 storage domains 1. Gluster backed 2. iSCSI SAN I use iSCSI SAN for the templates (backing disks) and would like to use Gluster storage domain for template instances. In VMware I could create a linked clone on one storage linked to a template on another. Is this possible with oVirt? via GUI or API? Thanks in advance, Shantur

Hello On a fresh installation of a 4.4.4 node, I configured network so as to get dhcp delivered IP for gluster and migration services. After IPs have been delivered, they can't be pingued and vms migrations fail. All work as expected once I reactivate each bridge with nmcli/nmtui...

Right Glusterfs Config on HA Server
by Marcel d'Heureuse 04 Mar '21

04 Mar '21

Hi Guys or Girls, I have a problem in a productive system. We use three Servers which have a Raid 5 with four Harddrives SATA 8 TB 7200 rpms. The Systems are interconnected for Glusterfs with 1 GB/s. The Network Load between all three servers are between 5 and 8 % of the network. The Glusterfs has a separate VLAN which complete isolated from other networks. Find attached a small drawing. On that server we rum as HA and there are 8 VMs installed. Most of the VMs working well but if there is high load on the system some of the VM can't write the Data in a "good" speed on the disks. The Glusterfs is configured as Replica on the Raid5 disk which is as Jbob in Glusterfs defined. If i take a look on the iostats i can see that the Harddisk have round 50 open connections some of the glusterfs and a lot of the vms. In side the VMs i can see long iowaiting times from 300 up to 600 ms. With is on case of a Posgresql database very long. Should we configure the Raid5 controller out that the controller only should 4 disks with 8 TB and Glusterfs should connect directly to the /dev/sd[b-e]? What do you think? Will SSD HDD will help on performance but the same config with Raid5 and Jbod could be the bigger problem. Thanks Marcel

Newly uploaded disk stuck in 'Finalizing Failure' status
by n.bouwhuis＠speakup.nl 03 Mar '21

03 Mar '21

Hey there, A few days ago, I tried to create a new template using one of the Ansible playbooks I frequently use. This time, the upload of the disk failed, possibly due to an unrelated error. The disk is now stuck in Ovirt. It has the status 'Finalizing Failure' and it's locked, thus I cannot remove it. Trying to unlock the disk with the 'unlock_entity.sh' helper utility does not help. The utility says it has completed it task successfully but the disk remains in this state. I decided to check the logs, and see that `engine.log` gets spammed with these lines every 10 seconds ``` 2021-03-03 09:05:38,335Z WARN [org.ovirt.engine.core.bll.storage.disk.image.TransferDiskImageCommand] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-45) [redacted] Failed to stop image transfer session. Ticket does not exist for image '[disk uuid]' ``` How can I force Ovirt to remove this disk? I presume the upload failure itself is a different error, possibly related to our setup. Hence this is not the topic of this thread. I just want to know how I can remove these disks. Thanks, Nick

SHE upgrade from 4.3 to 4.4 doubts
by Gianluca Cecchi 03 Mar '21

03 Mar '21

Hello, I would like to get some clarifications about the SHE environment upgrade from 4.3.10 to 4.4.4. Example scenario two hosts, both configured as HE hosts. Interested both in iSCSI environment and in FC environment. Going through here: https://www.ovirt.org/documentation/upgrade_guide/#Upgrading_the_Manager_to… I have some doubts: 1) general one between step 5 and 6 in section 4.4, actually the current 4.3 engine VM is still running its OS (even if with ovirt-engine service stopped) and the VM is running on the host you are going to scratch. So I think before scratching the host and reinstalling it (step 6), it should be clarified some step like - shutdown engine VM - shutdown host (is it ok in clean way or do I have to simply power off it....?) - install from scratch ovirt-ng node 4.4.4 on host 2) general one why in external engine upgrade guide it is not specified to stop ovirt-engine service before executing the backup, while in SHE it is specified? See steps on section 2.3 here: https://www.ovirt.org/documentation/upgrade_guide/#Upgrading_from_4-3 expected different behaviour? Or any change needed in the doc? 3) SHE when iSCSI and FC It is clear that one new domain is to be provided, intended for the new engine 4.4 VM It is clear that during install of the new host in 4.4 it is safe to have shared LUNs masked / not accessible so that you don't risk to corrupt current 4.3 data It is not clear in my opinion what to do before running the step 8 of 4.4 section: hosted-engine --deploy --restore-from-file=backup.bck a) iSCSI in general the configured iSCSI sessions are activated only when the host is being activated. So for example when you put host into maintenance, they are logged off. In this stage of upgrade what is expected I execute before running the hosted-engine --deploy command? Will the command log in into iSCSI sessions during itsmexecution (because of the restore) or do I have to create / log in the connections before running it? b) FC what should I have on host before running the command? Only the current LUns (+ the new one intended for new hosted engine VM) visible, so that I see all of them as output of "multipath -l" command and then the hosted-engine --deploy command would mount the related filesystems and so on..? Possibly it would be nice to have an example output of the hosted-engine --deploy --restore-from-file=backup.bck command inside the doc page.... to see its expected workflow Thanks for reading, Gianluca

Upgrade from 4.3.5 to 4.3.10 HE Host issue
by Vrgotic, Marko 03 Mar '21

03 Mar '21

Hi oVirt, Yesterday I upgraded one of my oVIrt platform from 4.3.5 to 4.3.10. Platform has 10Hosts with 3Hosts as Hosts for HA. Before upgrade, all three Hosts were acknowledged Hosts for HE (little happy crown). Pre upgrade: Host1 – HE available host Host2 – HE current host Host3 – HE available host Upgraded first HE to 4.3.10, than started with HE Hosts – post upgrade of Host2, the crown disappeared and did not show up. This happens sometimes, and I usually reinstall the host, than execute HE UNDEPLOY and DEPLOY, which fixes the state. However, this time, after such actions, the server is still not an acknowledged HE host – no crown. However, if I try to remove it, oVIrt says that looks like HE is deploy on it and need to be removed, but command “hosted-engine –vm-status” says you must deploy first. I removed the Host, reinstalled the OS on it, deployed it again as new, synced all networks, than deploy once more with HE Deploy, still same issue. Any suggestions? ----- kind regards/met vriendelijke groeten Marko Vrgotic Sr. System Engineer @ System Administration ActiveVideo o: +31 (35) 6774131 m: +31 (65) 5734174 e: m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com> w: www.activevideo.com<http://www.activevideo.com> ActiveVideo Networks BV.

How to enable nested virtualization
by miguel.garcia＠toshibagcs.com 02 Mar '21

02 Mar '21

Hi all, We are trying to run virtual box in a vm that is running over ovirt platform. I had followed the instruction to enable nested virtualization on host as described in this document https://ostechnix.com/how-to-enable-nested-virtualization-in-kvm-in-linux/ However I was not able to enable nested virtualization to the vm since nothing is listed from virsh console. Also tryed to edit vm configuration lookig up for "cpu mode" or "copy cpu configuration as host" Also from oVirt admin portal I had enabled host for nested virtualization through Compute > Host > selected Host > edit > Kernel Nested virtualization checked. But the host still returns: $ cat /sys/module/kvm_intel/parameters/nested N

Hi I have created a couple of bonding interfaces in the administrator portal, due to some miss configuration I had to break the bond interfaces, what I observe is that after breaking the bonding interfaces the KVM host becomes non operational and it stays in such state unless I add the bonding interfaces back. Anyone have observed this behaviour? Thanks

2 Node oVirt Cluster
by justin.lamp96＠gmail.com 01 Mar '21

01 Mar '21

Hey there, I tried using oVirt for some time now and like to convert my main Proxmox Cluster (2 Nodes + RPI for Quorum) to oVirt. But I obvioulsy need three servers to do HA. Now I am asking myself: can't I just use the PI as an arbiter node for the Selfhosted-Engine on gluster? I tried running the playbook already, but it's always failing and even if the gluster deployment would go through, it would most likely fail aftwards, right? Before I waste too much energy and time into that, does anyone of you guys use a 2 node cluster? And no I can't add another node (energy + space + money)! Also I know with doing that I'm totally on my own etcetera Thanks!

oVirt4.1 add host error. can i upgrade from 4.1 to 4.4? without updating sequentially 4.1-4.2-4.3-4.4
by grig.4n＠gmail.com 01 Mar '21

01 Mar '21

HI! There is an oVirt 4.1 self-hosted engine cluster of two hosts and a storage connected via iscsi. When trying to add another host, it gives an error: "ERROR otopi.context context._executeMethod:151 Failed to execute stage 'Setup validation': Cannot locate vdsm package, possible cause is incorrect channels". Older hosts on Centos 7.5.1804, last on Centos 7.9.2009. Is it possible to go from 4.1 to 4.4 using the third host as the main one for the transfer?

Cant add vm network with vlan to bonded interface
by murat.celebi＠dbpro.com.tr 01 Mar '21

01 Mar '21

Hello, I am new to ovirt and try to migrate my companies vmware infra to ovirt. The Engine setup went fine without any problems. These are the steps which I am doing and having problems. 1. Prepare the KVM host by installing the RPM's. 2. Add the kvm host to the engine. Everything is working fine at this point. 3. I am creating a new Network for vm usage named VLAN10. And I am tagging the network with vlan id 10. 4. I am bonding two 25Gb/s interface's with balance-xor mode with the name bond1. 5. When I add the network VLAN10 to the bond1 interface I cant see the logical network assigned to the bond. After this step I am not able to delete the bond since I am getting errors when I try to delete the bond. Any help would be greatly appreciated. Thank you
