It doesn't matter if it's a fresh install or import. I go to ui and edit vm and change to one of the default size templates, usually large, it boots with no nic and I can add a nic once it's booted and restart it, then it gets an IP and is fine unless you shut it down. In that case, you have to go through setting size and adding nic after vm boot. Any help would be appreciated. Thanks in advance/

import VM from Qemu-KVM
by Enrico Becchetti 15 Dec '25

15 Dec '25

Dear all, I've a question about import VM from an external hypervisor. My oVirt is 4.3: N. 3 Dell R7525 servers with CentOS 7 SAN BROCADE and HPE MSA P 2050 (domain: DATA_FC_P2050) 10Gbps network, NFS Server (domain: NFS) I need to import a virtual machine running on a Qemu-KVM server into ovirt. The file type is qcow2, about 100GB. I tried with GUI "Storage->Disk->Upload" but I've got an error: "Connection to ovirt-imageio-proxy service has failed. Make sure the service is installed, configured, and the ovirt-engine certificate is registered as a valid CA in the browser." Can you tell me the correct sequence for this operation and for importing and running the virtual machine in ovirt? Thanks a lot Best Regards Enrico -- __________________________________________________________________________ Enrico Becchetti Servizio di Calcolo e Reti Istituto Nazionale di Fisica Nucleare - Sezione di Perugia Via Pascoli,c/o Dipartimento di Fisica 06123 Perugia (ITALY) Phone:+39 075 5852777 Mobile: +39 075 9696225 FAX: +39 075 5847296 Microsoft Teams: becchett(a)infn.it Mail: Enrico.Becchetti<at>pg.infn.it Pagina web personale: https://www.pg.infn.it/home/enrico-becchetti _________________________________________________________________________

swtpm
by Winfried de Heiden 12 Dec '25

12 Dec '25

Hi all, I'm currently running oVirt 4.5.7 and added a (virtual) tpm2 device to one of my VM's for the sake of experimenting with tpm2 and it's commands. Experimenting means breaking stuff :) and I need to reset the tpm device on a regular base. Using kvm and virsh; this is fairly easy: "rm -rf /var/lib/libvirt/swtpm/$(virsh domuuid tpm2)/tpm2" will do to start with a new virtual tpm device. On oVirt, how can I reset (destroy, create new one) the virtual tpm device? Thanks! Winfried

Installing oVirt 4.5 on RHEL 9 (Offline / NIST 800-53 Compliance)
by Rockwell, Jenn - US 11 Dec '25

11 Dec '25

Hi all, I’m working on setting up production oVirt 4.5 with a self-hosted engine on RHEL 9 in an offline, NIST 800-53 environment. The server does not have internet access, but I can download repositories and packages separately and hand transfer them over. I’ve looked through the available documentation, but aside from https://www.ovirt.org/download/install_on_rhel.html, I haven’t found details on which additional repositories (RHEL, oVirt, dependencies, etc.) are required for a full installation. I’m looking for guidance on the best approach for this type of setup. Ideally, whether there’s a simpler or supported method to get a self-hosted engine running in an offline environment without having to mirror all repositories manually. Thanks in advance for any advice or pointers.

Need advice with 3 servers and 1 SAN
by provensen＠aol.com 11 Dec '25

11 Dec '25

I am new to oVirt, and I am trying to find the right solution for my LAN. On an air-gapped network, I have 3 Dell PowerEdge servers running Alma Linux 9 and 1 IBM SAN. I have 3 iSCSI connections from the IBM SAN to the 3 Dell servers. I am looking to install oVirt as 3 Enterprise Linux hosts on the 3 Dell servers. I need the 3 Enterprise Linux hosts to have shared storage, so all 3 hosts can access all of the virtual machines. I need the storage to have high availability, so if 1 host goes down the virtual machines can run on the other hosts. Which kind of storage do I use for this? NFS, iSCSI, cluster...etc? Also, do I connect the IBM SAN to only 1 host, and share that IBM SAN storage with the other 2 hosts, or would I create 3 separate iSCSI connections to each host? I would really appreciate any assistance from anyone. Thank you.

Unable to upload or download iso via admin portal
by Igor Filipovic 09 Dec '25

09 Dec '25

Hi, I'm having a trouble on fresh 4.4.10.7 installation (on oracle linux), I'm not able to upload or download any file using storage domain upload image function. I've imported CA certificate and have tried on several browsers (firefow, chrome,edge), on different computers (and browsers are green - claiming that I'm securely connected), but I'm always getting error regarding CA certificate when I test connection, or when I try to upload ISO image. I've tried to upload ISO image via cli commands (upload_disk.py), and that scenario was successful, however this method It is not very convenient for my co-workers. I have 5 physical hosts, one is dedicated to run ovirt-engine, and other 4 are kvm hypervisors. When I try to upload ISO this is what engine.log logs: 2023-04-08 11:00:28,339+02 INFO [org.ovirt.engine.core.bll.storage.disk.image.TransferImageStatusCommand] (default task-2) [f6b62add-0a0c-45ee-a985-a76171843382] Running command: TransferImageStatusCommand internal: false.

"400 Bad request" error logging in
by Dan O'Brien 19 Nov '25

19 Nov '25

This is even more mysterious now that I've discovered it's only a problem for ME and only when I'm logged in to Chrome. Safari and Edge work, and so does a Chrome private browsing window. Nonetheless, there seems to be a fix on the server side, if I'm correct. After entering credentials on the logon screen (internalsso), I get a "400 Bad Request" error in the browser and I'm seeing these errors in /var/log/httpd/error_log: [Wed Nov 19 14:37:04.988719 2025] [proxy_ajp:error] [pid 2364:tid 2392] AH03229: ajp_msg_append_cvt_string(): BufferOverflowException 4 8159 I found this post on the list https://lists.ovirt.org/archives/list/users@ovirt.org/thread/K4MBGS3ZD4LK6S… and these in the Red Hat knowledge base (must log in to view) https://access.redhat.com/solutions/1525873 https://access.redhat.com/solutions/732343 (for JBoss 6) https://access.redhat.com/solutions/6166212 (For JBoss 7, which I think oVirt 4.5 uses) The solution is to change a couple of settings in httpd.conf (or in httpd.conf.d): LimitRequestFieldsize 65536 ProxyIOBufferSize 65536 There's a corresponding setting that needs to be changed in JBoss/Wildfly. I think the standalone.xml file referred to in the KB articles is in /usr/share/ovirt-engine-wildfly/standalone/configuration Can someone confirm? Also, is oVirt 4.5 (4.5.7-0.master.20251029141850.git6e58a03353.el9, specifically) using 6 or 7? Running ./jboss-cli.sh from /usr/share/ovirt-engine-wildfly/bin fails with the error Failed to connect to the controller: The controller is not available at localhost:9990: java.net.ConnectException: WFLYPRT0053: Could not connect to remote+http://localhost:9990. The connection failed: WFLYPRT0053: Could not connect to remote+http://localhost:9990. The connection failed: Connection refused Is it listening on another port? I tried ./jboss-cli.sh --version but it wants to be connected

certs expired, now engine won't start
by Michael Thomas 18 Nov '25

18 Nov '25

I seem to have gotten myself into a bit of a pickle. My ovirt host certs (4-node 4.4.1 cluster) expired recently and I didn't notice until one of my hosts got fenced on Friday. I was finally able to get it back online by rebooting, telling the ovirt-engine the host had been rebooted (so that it didn't think VMs were running on it), and then going into maintenance mode and 'enroll certificates' to renew the certs. This worked with the second host as well. But I was unable to put the third host into maintenance mode because the engine claimed "Another power management action is already in progress". Sure enough, the task list showed the engine trying to take action against this host. It was stuck in that state for over an hour, so I finally poked the ovirt-engine database directly to fail these tasks: psql engine -c "UPDATE job SET status = 'FAILED', end_time = NOW() WHERE status NOT IN ('FINISHED', 'FAILED');" psql engine -c "UPDATE step SET status = 'FAILED', end_time = NOW() WHERE status NOT IN ('FINISHED', 'FAILED');" This got the tasks to clear, but the engine UI still claimed that the stuck host still had "Another power management action is already in progress". Then I made the fatal mistake of rebooting the ovirt-engine (which was still running on the fourth host with expired certs). Now my engine won't start, even when I try to start it on one of the host that had certs renewed. The libvirt logs indicate that it's because the vnc cert is expired: qemu-kvm: -object tls-creds-x509,id=vnc-tls-creds0,dir=/etc/pki/vdsm/libvirt-vnc,endpoint=server,verify-peer=no: The server certificate /etc/pki/vdsm/libvirt-vnc/server-cert.pem has expired Since I don't care about vnc access to the engine, is there a way to get the engine running again without vnc? Alternately, is there a way that I can manually get some of the more critical VMs running without an engine running? FWIW, I tried searching the list archives, but I get a 500 server error when trying to go to lists.ovirt.org. --Mike
