Hi! I would need some help removing a snapshot that looks like this. How do i remove it manually or fix snapshot definition? ----------------- Error while executing action: TUN_SALDC01: * The requested snapshot has an invalid parent, either fix the snapshot definition or remove it manually to complete the process. ----------------- And when i look at the disk on tha tnapshot it show as this: [cid:98462a7f-dbb6-447e-925a-5b170883d7c7] And general info: [cid:9264e2e0-459f-4b54-aba7-08b3bf1f4068]

How to diable dhcp in ovirt network
by Adam Xu 17 Aug '20

17 Aug '20

Hi everyone Recently, when I install okd on ovirt. The installation process was failed because the vm automatically acquired an IP address from DHCP before the installer assigned it. Our DHCP is enabled by a layer 3 switch, I tried to diable dhcp using network filter. but there is no entry related to blocking the DHCP feature. Is there any way for ovirt to disable DHCP? -- Adam Xu

oVirt nested on oVirt works, when you enable MAC spoofing on host VMs
by thomas＠hoberg.net 13 Aug '20

13 Aug '20

Howto: Create a new network profile that doesn't have the MAC spoofing filter included. In my case I used one without any filters, you may want to be more careful. Background: I had tried the nested approach with the default settings and found that the hosted-engine setup worked just find to the point where it was running as a nested VM on the install node, but that it failed to tie in the other gluster nodes or to communicate to the outside: There was something wrong with the network, but no obivous failures. I tried using other, simpler "client hypervisors" (it's all KVM anyway) VirtualBox and 'native' KVM and the symptoms were the same: The VMs ran just fine, but the network didn't connect. And then I remembered that obviously a Hypervisor need to override the MAC for each client VM if you want full network access and I had come across "no-mac-spoofing" often enough it somehow stayed on my mind... and finally it clicked. Anyhow, validing full functionality now and the main interest in this is the ability to do a full simulation/testing of oVirt 4.3->4.4 upgrades on 3-node HCI setups, which I'd rather not do on the live physical system. Of course, it's also quite cool!

Support for Shared SAS storage
by Vinícius Ferrão 13 Aug '20

13 Aug '20

Hello, I’ve two compute nodes with SAS Direct Attached sharing the same disks. Looking at the supported types I can’t see this on the documentation: https://www.ovirt.org/documentation/admin-guide/chap-Storage.html There’s is local storage on this documentation, but my case is two machines, both using SAS, connected to the same machines. It’s the VRTX hardware from Dell. Is there any support for this? It should be just like Fibre Channel and iSCSI, but with SAS instead. Thanks,

Is the udev settling issue more wide spread? Getting failed 'qemu-img -convert' also while copying disks between data and vmstore domains
by thomas＠hoberg.net 12 Aug '20

12 Aug '20

While trying to diagnose an issue with a set of VMs that get stopped for I/O problems at startup, I try to deal with the fact that their boot disks cause this issue, no matter where I connect them. They might have been the first disks I ever tried to sparsify and I was afraid that might have messed them up. The images are for a nested oVirt deployment and they worked just fine, before I shut down those VMs... So I first tried to hook them as secondary disks to another VM to have a look, but that just cause the other VM to stop at boot. Also tried downloading, exporting, and plain copying the disks to no avail, OVA exports on the entire VM fail again (fix is in!). So to make sure copying disks between volumes *generally* work, I tried copying a disk from a working (but stopped) VM from 'vmstore' to 'data' on my 3nHCI farm, but that failed, too! Plenty of space all around, but all disks are using thin/sparse/VDO on SSD underneath. Before I open a bug, I'd like to have some feedback if this is a standard QA test, this is happening to you etc. Still on oVirt 4.3.11 with pack_ova.py patched to wait for the udev settle, This is from the engine.log on the hosted-engine: 2020-08-12 00:04:15,870+02 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-engineScheduled-Thread-67) []

oVirt 4.4.0 Release is now generally available
by Sandro Bonazzola 12 Aug '20

12 Aug '20

oVirt 4.4.0 Release is now generally available The oVirt Project is excited to announce the general availability of the oVirt 4.4.0 Release, as of May 20th, 2020 This release unleashes an altogether more powerful and flexible open source virtualization solution that encompasses hundreds of individual changes and a wide range of enhancements across the engine, storage, network, user interface, and analytics, as compared to oVirt 4.3. Important notes before you install / upgrade Some of the features included in the oVirt 4.4.0 release require content that will be available in CentOS Linux 8.2 but cannot be tested on RHEL 8.2 yet due to some incompatibility in the openvswitch package that is shipped in CentOS Virt SIG, which requires rebuilding openvswitch on top of CentOS 8.2. The cluster switch type OVS is not implemented for CentOS 8 hosts. Please note that oVirt 4.4 only supports clusters and datacenters with compatibility version 4.2 and above. If clusters or datacenters are running with an older compatibility version, you need to upgrade them to at least 4.2 (4.3 is recommended). Please note that in RHEL 8 / CentOS 8 several devices that worked on EL7 are no longer supported. For example, megaraid_sas driver is removed. If you use Enterprise Linux 8 hosts you can try to provide the necessary drivers for the deprecated hardware using the DUD method (See users mailing list thread on this at https://lists.ovirt.org/archives/list/users@ovirt.org/thread/NDSVUZSESOXEFJ… ) Installation instructions For the engine: either use the oVirt appliance or install CentOS Linux 8 minimal by following these steps: - Install the CentOS Linux 8 image from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x8… - dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44.rpm - dnf update (reboot if needed) - dnf module enable -y javapackages-tools pki-deps postgresql:12 - dnf install ovirt-engine - engine-setup For the nodes: Either use oVirt Node ISO or: - Install CentOS Linux 8 from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x8…, selecting the minimal installation. - dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44.rpm - dnf update (reboot if needed) - Attach the host to the engine and let it be deployed. Update instructionsUpdate from oVirt 4.4 Release Candidate On the engine side and on CentOS hosts, you’ll need to switch from ovirt44-pre to ovirt44 repositories. In order to do so, you need to: 1. dnf remove ovirt-release44-pre 2. rm -f /etc/yum.repos.d/ovirt-4.4-pre-dependencies.repo 3. rm -f /etc/yum.repos.d/ovirt-4.4-pre.repo 4. dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44.rpm 5. dnf update On the engine side you’ll need to run engine-setup only if you were not already on the latest release candidate. On oVirt Node, you’ll need to upgrade with: 1. Move node to maintenance 2. dnf install https://resources.ovirt.org/pub/ovirt-4.4/rpm/el8/noarch/ovirt-node-ng-imag… 3. Reboot 4. Activate the host Update from oVirt 4.3 oVirt 4.4 is available only for CentOS 8. In-place upgrades from previous installations, based on CentOS 7, are not possible. For the engine, use backup, and restore that into a new engine. Nodes will need to be reinstalled. A 4.4 engine can still manage existing 4.3 hosts, but you can’t add new ones. For a standalone engine, please refer to upgrade procedure at https://ovirt.org/documentation/upgrade_guide/#Upgrading_from_4-3 If needed, run ovirt-engine-rename (see engine rename tool documentation at https://www.ovirt.org/documentation/admin-guide/chap-Utilities.html ) When upgrading hosts: You need to upgrade one host at a time. 1. Turn host to maintenance. Virtual machines on that host should migrate automatically to a different host. 2. Remove it from the engine 3. Re-install it with el8 or oVirt Node as per installation instructions 4. Re-add the host to the engine Please note that you may see some issues live migrating VMs from el7 to el8. If you hit such a case, please turn off the vm on el7 host and get it started on the new el8 host in order to be able to move the next el7 host to maintenance. What’s new in oVirt 4.4.0 Release? - Hypervisors based on CentOS Linux 8 (rebuilt from award winning RHEL8), for both oVirt Node and standalone CentOS Linux hosts. - Easier network management and configuration flexibility with NetworkManager. - VMs based on a more modern Q35 chipset with legacy SeaBIOS and UEFI firmware. - Support for direct passthrough of local host disks to VMs. - Live migration improvements for High Performance guests. - New Windows guest tools installer based on WiX framework now moved to VirtioWin project. - Dropped support for cluster level prior to 4.2. - Dropped API/SDK v3 support deprecated in past versions. - 4K block disk support only for file-based storage. iSCSI/FC storage do not support 4K disks yet. - You can export a VM to a data domain. - You can edit floating disks. - Ansible Runner (ansible-runner) is integrated within the engine, enabling more detailed monitoring of playbooks executed from the engine. - Adding and reinstalling hosts is now completely based on Ansible, replacing ovirt-host-deploy, which is not used anymore. - The OpenStack Neutron Agent cannot be configured by oVirt anymore, it should be configured by TripleO instead. This release is available now on x86_64 architecture for: * Red Hat Enterprise Linux 8.1 * CentOS Linux (or similar) 8.1 This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: * Red Hat Enterprise Linux 8.1 * CentOS Linux (or similar) 8.1 * oVirt Node 4.4 based on CentOS Linux 8.1 (available for x86_64 only) See the release notes [1] for installation instructions and a list of new features and bugs fixed. If you manage more than one oVirt instance, OKD or RDO we also recommend to try ManageIQ <http://manageiq.org/>. In such a case, please be sure to take the qc2 image and not the ova image.

Reverting to Snapshot
by Christian Reiss 12 Aug '20

12 Aug '20

Hey folks, this, I hope, is a trivial question. But I really can't find the button for it. If you take a snapshot of any vm - how do you revert to that snapshot, discarding all changes after? I see options to clone, delete, take snapshot, preview... but revert? Really in the true sense of "discard all changes, go back to this snapshot state". What am I not seeing here? :) -- with kind regards, mit freundlichen Gruessen, Christian Reiss

oVirt Node 4.1.1 Hosted Engine Deployment Fibre Channel No LUNS found
by hkexdong＠yahoo.com.hk 12 Aug '20

12 Aug '20

I've an external RAID subsystem connect to the host by SAS cable (SFF-8644). I follow the instructions of the RAID card manufacture. Include the driver during host installation. And I can see the created RAID volumes (LUNs) available in "Installation Destination". Although I choose to install the engine in host local disk. The installation success and I proceed to hosted engine deployment by Cockpit. And now I stuck at part 4 Storage. I believe "Storage Type" select "Fibre Channel" is correct even I'm not using fibre cable. As NFS and iSCSI are utilize network. I confirm there are 2 RAID volume (LUN0 & LUN1) created in the external RAID subsystem. Why oVirt cannot discover them. What could be wrong :(

Hosted Engine Deployment stuck at 3. Prepare VM
by hkexdong＠yahoo.com.hk 12 Aug '20

12 Aug '20

oVirt Node version is 4.4.1. This version can successful deploy before. But after I compile the RAID driver. It now stuck at Prepare VM. The last message is "[ INFO ] TASK [ovirt.hosted_engine_setup : Install ovirt-engine-appliance rpm]" According to the instructions from RAID controller manufacture. I'd install the "kernel-headers-xxx.rpm" and "kernel-devel-xxx.rpm" which extracted from official CentOS 8.2.2004 ISO. Also include a bunch of packages for compile driver (e.g. gcc, make, zlib-devel, etc.) I think those packages ruined the deployment. But I still want to know it actually stuck at which part and the reason. Is there any way to check the deployment log?

migrating standalone engine to selfhosted and upgrade from 4.3 to 4.4 in one step
by Jiří Sléžka 11 Aug '20

11 Aug '20

Hello, I have 4 host cluster managed with standalone engine in version 4.3 and I would like to migrate this standalone engine to 4.4 as hosted engine. I have two new hosts which I would like to use as base for new HE cluster. (new hosts are Intel based, old ones are AMD Opteron based - new cluster will have 4.4 compatibility, old one have to stay at 4.2 compatibility level). I red this https://www.ovirt.org/documentation/migrating_from_a_standalone_manager_to_… but the question is: Can I migrate and upgrade in one step? Have anybody did that already? If it is not possible what is a suggested approach? Thanks for help Jiri

OVA export creates empty and unusable images
by thomas＠hoberg.net 10 Aug '20

10 Aug '20

I've tested this now in three distinct farms with CentOS7.8 and the latest oVirt 4.3 release: OVA export files only contain an XML header and then lots of zeros where the disk images should be. Where an 'ls -l <vmname>.ova' shows a file about the size of the disk, 'du -h <vmname>.ova' shows mere kilobytes, 'strings <vmname>.ova' dumps the XML and then nothing but repeating zeros until the end of the file. Exporting existing VMs from a CentOS/RHEL 7 farm and importing them after a rebuild on CentOS/RHEL 8 would seem like a safe migration strategy, except when OVA export isn't working. Please treat with priority!

Hi all, I am planning to build a 3 nodes hyperconverged system with oVirt, but I have a question. After having the system up and running with 3 nodes (compute and storage), if I need some extra compute power can I add some other "compute" (with no storage) nodes as glusterfs clients to enhance the total compute power of the cluster and using the actual storage? Thank you and Best Regards. -- Benedetto Vassallo Responsabile U.O.

Do distinct export domains share a name space? Can't export a VM, because it already exists in an unattached export domain...
by thomas＠hoberg.net 10 Aug '20

10 Aug '20

After OVA export/import was a) recommended against b) not working with the current 4.3 on CentOS 7, I am trying to make sure I keep working copies of critical VMs before I test if the OVA export now works properly, with the Redhat fix from 4.4. applied to 4.3. Long story short, I have an export domain "export", primarily attached to a 3 node HCI gluster-cluster and another domain "exportMono", primarily attached to a single node HCI gluster-cluster. Yes I use an export domain for backup, because, ...well there is no easy and working alternative out of the box, or did I overlook something? But of course, I also use an export domain for shipping between farms, so evidently I swap export domains like good old PDP-11 disk cartridges.... or at least I'd like to. I started by exporting VM "tdc" from the 1nHCI to exportMono, reattached that to 3nHCI for am import. Import worked everything fine, transfer succeed. So I detach exportMono, which belongs to the 1nHCI cluster. Next I do the OVA export on 1nHCI, but I need to get the working and reconfigured VM "tdc" out of the way on 3nHCI, so I dump it into the "export" export domain belonging to 3nHCI, because I understand I can't run two copies of the same VM on a single cluster. Turns out I can' export it, because even if the export domain is now a different one and definitely doesn't contain "tdc" at all, oVirt complains that the volume ID that belongs to "tdc" already exists in the export domain.... So what's the theory here behind export domains? And what's the state of their support in oVirt 4.4? I understand that distinct farms can't share an export domain, because they have no way of coordinating properly. Of course I tried to use one single NFS mount for both farms but the second farm properly detected the presense of another and required a distinct path. But from the evidence before me, oVirt doesn't support or like the existance of more than one export domain, either: Something that deserves a note or explanation. I understand they are deprecated in 4.3 already, but since they are also the only way to manage valuable VM images moving around, that currently works with the GUI on oVirt 4.3 it would be nice to have these questions answered.
