Dear All, In our Ovirt Engine Infrastructure, recently we have received an alert for one of our "Storage Domain" The alert is as mentioned below---- =================================== Storage domains with IDs [fb34e5b7-e850-4d66-ab47-3011d2000338] could not be synchronized. To synchronize them, please move them to maintenance and then activate. ========================================================== What is the consequence of this alert, if we ignore this what can happen to the infra, are we going to face any issue with the VMs, currently this infra is under production

Hello! We have a oVirt 4.5.6-1.el8 cluster. oVirt node Centos Stream 8 based. (5pcs) oVirt Hosted Engine Centos stream 8 based. We installed the hosts from an ISO image and the Hosted Engine we deployed from such a host. Link: https://resources.ovirt.org/pub/ovirt-4.5/iso/ovirt-node-ng-installer/4.5.5… How can we switch to Centos Stream 9 OS in the simplest way without downtime? Thanks in advance for the answer!

oVirt networks
by Enrico Becchetti 28 Aug '24

28 Aug '24

Dear all, Ineed your help to understand how to configure the network of a new oVirt cluster. Mynew system will have a 4.3 engine thatruns in a virtual machine, andsome Dell R7525 AMD EPYC hypervisors, eachholding two 4-port PCI network cards. These servers will have node-ovirt image again in version 4.3. As for the network, there are two HPE Aruba 2540G, non-stackable, with 24 1Gbs ports and 2 10Gbs uplinks to the star center. This is a simplified scheme: My goal is to make the most of the server's 8 ethernet interfaces to have both reliability and maximum possible throughput. This cluster will have two virtual networks, one forovirt management and one for the traffic of individual virtual machines. With that said here's what my idea is. I would like to have two links aggregated by 4Gbs, one for ovrtmgt and the other for vmnet. With the ovirt web interface I can createan active-passive "Mode 1" bond, but this won'tallow me to go beyond 1Gbs. Alternatively I could create a "Mode 4" bond 802.3ad but unfortunately the switches are not stacked and therefore not even this solution applies. This is an example with active passive configuration: Can you tell me if ovirt can generate//nested bonds? Or do you have other solutions ? Thanks a lot !

Hi. I have created a new storage domain (data domain, storage type nfs) to use it to upload iso images. I have so uploaded a new iso and then attach the iso to a new vm. But when I try to boot the vm I obtain this error: booting from dvd/cd... boot failed: could not read from cdrom (code 0005) no bootable device The iso file has been uploaded with success in the data storage domain and so the vm lets my attach the iso to the vm in the boot settings. Can you help me? Thank you

Hi, Migrating VMs from Vmware works nice in the UI but it's slow. With https://blogs.oracle.com/scoter/post/how-to-migrate-vmware-vsphere-to-oracl… i'm trying to import exported VM virt-v2v \ –o rhv-upload \ –oc https://<OLVM-ENGINE-PORTAL>/ovirt-engine/api \ -op /root/olvm-admin-password-file \ -oo rhv-cacert=/root/ovirt-cacert.pem \ -oo rhv-cluster=<OLVM-CLUSTER> \ -os <OLVM_STORAGE_DOMAIN> \ -of qcow2 \ -oo rhv-direct \ --network <OLVM-NETWORK> \ -i libvirtxml <LOCAL-XML-FILE> I tried everything possible but still there is an error virt-v2v: error: no -oo (output options) are allowed here If reporting bugs, run virt-v2v with debugging enabled and include the complete output: virt-v2v -v -x [...] Any idea?

Problem with Glusterfs Distributed-Replicated volume almost full but only less than 50% used by files.
by Olivier 22 Jul '24

22 Jul '24

Hi, I have a weird problem with my couple Glusterfs-oVirt: I had two data domain for my VMs on oVirt. The main one (data) is a Distributed-Replicate with 2 x 3 = 6 bricks of ~ 1,4 Tb on 3 servers (2 bricks by server). It was an extend of a previous 1 x 3 = 3 Replicated volume on the same servers. I had one new disk (and one new brick) on each of these 3 servers. My concern is the reported use of this volume (almost 100%). a df -h give me : df -h . Filesystem Size Used Avail Use% Mounted on ovirt1.pmmg.priv:/data 3.4T 3.3T 84G 98% /rhev/data-center/mnt/glusterSD/ovirt1.pmmg.priv:_data but a du of the same partition give me : du -hs /rhev/data-center/mnt/glusterSD/ovirt1.pmmg.priv:_data 1.4T /rhev/data-center/mnt/glusterSD/ovirt1.pmmg.priv:_data and there no hidden folder I could miss in this mount point. The weird point (the second one) is when I delete a VMs and is disks (main disk and snapshot) I doesn't get back some space on these volume. Does anyone have an idea of these problem ? Thank's Here the Info of the gluster volume : gluster volume info data Volume Name: data Type: Distributed-Replicate Volume ID: 22b7942e-2952-40d4-ab92-64636e3ce409 Status: Started Snapshot Count: 0 Number of Bricks: 2 x 3 = 6 Transport-type: tcp Bricks: Brick1: ovirt1.pmmg.priv:/gluster_bricks/data/data Brick2: ovirt2.pmmg.priv:/gluster_bricks/data/data Brick3: ovirt3.pmmg.priv:/gluster_bricks/data/data Brick4: ovirt1.pmmg.priv:/gluster_bricks/data_extend1/data Brick5: ovirt2.pmmg.priv:/gluster_bricks/data_extend1/data Brick6: ovirt3.pmmg.priv:/gluster_bricks/data_extend1/data Options Reconfigured: features.shard-block-size: 128MB cluster.lookup-optimize: off server.keepalive-count: 5 server.keepalive-interval: 2 server.keepalive-time: 10 server.tcp-user-timeout: 20 performance.client-io-threads: on nfs.disable: on storage.fips-mode-rchecksum: on transport.address-family: inet performance.quick-read: off performance.read-ahead: off performance.io-cache: off performance.low-prio-threads: 32 network.remote-dio: disable cluster.eager-lock: enable cluster.quorum-type: auto cluster.server-quorum-type: server cluster.data-self-heal-algorithm: full cluster.locking-scheme: granular cluster.shd-max-threads: 8 cluster.shd-wait-qlength: 10000 features.shard: on user.cifs: off cluster.choose-local: off client.event-threads: 4 server.event-threads: 4 storage.owner-uid: 36 storage.owner-gid: 36 network.ping-timeout: 20 performance.strict-o-direct: on cluster.granular-entry-heal: enable features.trash: off

oVirt 4.5.5 compatibility with CPU
by jakov.jelinic＠adriatic.hr 18 Jul '24

18 Jul '24

Hi, We plan to install ovirt node 4.5.5 (https://resources.ovirt.org/pub/ovirt-4.5/iso/ovirt-node-ng-installer/) on our 2 new servers, but looking at the documentation (https://www.ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engin…) it seems that oVirt is not compatible with our CPU Intel Xeon Silver 4410Y 12C 150 W 2 .0 GHz processor? Can you help us?

Start VM with option -machine smm=off
by Kalil de A. Carvalho 16 Jul '24

16 Jul '24

Hello all. I'm trying to workaround the problem reported here: https://gitlab.com/qemu-project/qemu/-/issues/1198 but I did not find out how to start up the VM with the option -machine smm=off like sead on the lsit above. I guess that it is possible to run the command using the qemu command but I think that I will lose the management of it. It is possible to startup up a VM with this option using the oVirt GUI ou virsh? Best regards -- Atenciosamente, Kalil de A. Carvalho

New oVirt release ???
by Diggy 15 Jul '24

15 Jul '24

Any movement towards a new oVirt release now that CentOS Stream 8 is officially at EOL and the current engine is based on it? Do I see oVirt v4.6 in my near future? I'm looking for a reason to build a fresh oVirt environment and migrate our 100+ VMs to it. :) ---
