Please, Please Help - New oVirt Install/Deployment Failing - "Host is not up..."
by Matthew J Black 18 Jan '24

18 Jan '24

Hi Everyone, Could someone please help me - I've been trying to do an install of oVirt for *weeks* (including false starts and self-inflicted wounds/errors) and it is still not working. My setup: - oVirt v4.5.3 - A brand new fresh vanilla install of RockyLinux 8.6 - all working AOK - 2*NICs in a bond (802.3ad) with a couple of sub-Interfaces/VLANs - all working AOK - All relevant IPv4 Address in DNS with Reverse Lookups - all working AOK - All relevant IPv4 Address in "/etc/hosts" file - all working AOK - IPv6 (using "method=auto" in the interface config file) enabled on the relevant sub-Interface/VLAN - I'm not using IPv6 on the network, only IPv4, but I'm trying to cover all the bases. - All relevant Ports (as per the oVirt documentation) set up on the firewall - ie firewall-cmd --add-service={{ libvirt-tls | ovirt-imageio | ovirt-vmconsole | vdsm }} - All the relevant Repositories installed (ie RockyLinux BaseOS, AppStream, & PowerTools, and the EPEL, plus the ones from the oVirt documentation) I have followed the oVirt documentation (including the special RHEL-instructions and RockyLinux-instructions) to the letter - no deviations, no special settings, exactly as they are written. All the dnf installs, etc, went off without a hitch, including the "dnf install centos-release-ovirt45", "dnf install ovirt-engine-appliance", and "dnf install ovirt-hosted-engine-setup" - no errors anywhere. Here is the results of a "dnf repolist": - appstream Rocky Linux 8 - AppStream - baseos Rocky Linux 8 - BaseOS - centos-ceph-pacific CentOS-8-stream - Ceph Pacific - centos-gluster10 CentOS-8-stream - Gluster 10 - centos-nfv-openvswitch CentOS-8 - NFV OpenvSwitch - centos-opstools CentOS-OpsTools - collectd - centos-ovirt45 CentOS Stream 8 - oVirt 4.5 - cs8-extras CentOS Stream 8 - Extras - cs8-extras-common CentOS Stream 8 - Extras common packages - epel Extra Packages for Enterprise Linux 8 - x86_64 - epel-modular Extra Packages for Enterprise Linux Modular 8 - x86_64 - ovirt-45-centos-stream-openstack-yoga CentOS Stream 8 - oVirt 4.5 - OpenStack Yoga Repository - ovirt-45-upstream oVirt upstream for CentOS Stream 8 - oVirt 4.5 - powertools Rocky Linux 8 - PowerTools So I kicked-off the oVirt deployment with: "hosted-engine --deploy --4 --ansible-extra-vars=he_offline_deployment=true". I used "--ansible-extra-vars=he_offline_deployment=true" because without that flag I was getting "DNF timout" issues (see my previous post `Local (Deployment) VM Can't Reach "centos-ceph-pacific" Repo`). I answer the defaults to all of questions the script asked, or entered the deployment-relevant answers where appropriate. In doing this I double-checked every answer before hitting <Enter>. Everything progressed smoothly until the deployment reached the "Wait for the host to be up" task... which then hung for more than 30 minutes before failing. From the ovirt-hosted-engine-setup... log file: - 2022-10-20 17:54:26,285+1100 ERROR otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:113 fatal: [localhost]: FAILED! => {"changed": false, "msg": "Host is not up, please check logs, perhaps also on the engine machine"} I checked the following log files and found all of the relevant ERROR lines, then checked several 10s of proceeding and succeeding lines trying to determine what was going wrong, but I could not determine anything. - ovirt-hosted-engine-setup... - ovirt-hosted-engine-setup-ansible-bootstrap_local_vm... - ovirt-hosted-engine-setup-ansible-final_clean... - not really relevant, I believe I can include the log files (or the relevant parts of the log files) if people want - but that are very large: several 100 kilobytes each. I also googled "oVirt Host is not up" and found several entries, but after reading them all the most relevant seems to be a thread from these mailing list: `Install of RHV 4.4 failing - "Host is not up, please check logs, perhaps also on the engine machine"` - but this seems to be talking about an upgrade and I didn't gleam anything useful from it - I could, of course, be wrong about that. So my questions are: - Where else should I be looking (ie other log files, etc, and possible where to find them)? - Does anyone have any idea why this isn't working? - Does anyone have a work-around (including a completely manual process to get things working - I don't mind working in the CLI with virsh, etc)? - What am I doing wrong? Please, I'm really stumped with this, and I really do need help. Cheers Dulux-Oz

Grafana - Origin Not Allowed
by Maton, Brett 14 Dec '23

14 Dec '23

oVirt 4.5.0.8-1.el8 I tried to connect to grafana via the monitoring portal link from the dash and all panels are failing to display any data with varying error messages, but all include 'Origin Not Allowed' I navigated to Data Sources and ran a test on the PostgreSQL connection (localhost) which threw the same Origin Not Allowed error message. Any suggestions?

Multiple hosts stuck in Connecting state waiting for storage pool to go up.
by ivan.lezhnjov.iv＠gmail.com 06 Nov '23

06 Nov '23

Hi! We have a problem with multiple hosts stuck in Connecting state, which I hoped somebody here could help us wrap our heads around. All hosts, except one, seem to have very similar symptoms but I'll focus on one host that represents the rest. So, the host is stuck in Connecting state and this what we see in oVirt log files. /var/log/ovirt-engine/engine.log: 2023-04-20 09:51:53,021+03 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.GetCapabilitiesAsyncVDSCommand] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-37) [] Command 'GetCapabilitiesAsyncVDSCommand(HostName = ABC010-176-XYZ, VdsIdAndVdsVDSCommandParametersBase:{hostId='2c458562-3d4d-4408-afc9-9a9484984a91', vds='Host[ABC010-176-XYZ,2c458562-3d4d-4408-afc9-9a9484984a91]'})' execution failed: org.ovirt.vdsm.jsonrpc.client.ClientConnectionException: SSL session is invalid 2023-04-20 09:55:16,556+03 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-67) [] EVENT_ID: VDS_BROKER_COMMAND_FAILURE(10,802), VDSM ABC010-176-XYZ command Get Host Capabilities failed: Message timeout which can be caused by communication issues /var/log/vdsm/vdsm.log: 2023-04-20 17:48:51,977+0300 INFO (vmrecovery) [vdsm.api] START getConnectedStoragePoolsList() from=internal, task_id=ebce7c8c-6ded-454e-9aee-86edf72764ef (api:31) 2023-04-20 17:48:51,977+0300 INFO (vmrecovery) [vdsm.api] FINISH getConnectedStoragePoolsList return={'poollist': []} from=internal, task_id=ebce7c8c-6ded-454e-9aee-86edf72764ef (api:37) 2023-04-20 17:48:51,978+0300 INFO (vmrecovery) [vds] recovery: waiting for storage pool to go up (clientIF:723) Both engine.log and vdsm.log are flooded with these messages. They are repeated at regular intervals ad infinitum. This is one common symptom shared by multiple hosts in our deployment. They all have these message loops in engine.log and vdsm.log files. On all Running vdsm-client Host getConnectedStoragePools also returns an empty list represented by [] on all hosts (but interestingly there is one that showed Storage Pool UUID and yet it was still stuck in Connecting state). This particular host (ABC010-176-XYZ) is connected to 3 CEPH iSCSI Storage Domains and lsblk shows 3 block devices with matching UUIDs in their device components. So, the storage seems to be connected but the Storage Pool is not? How is that even possible? Now, what's even more weird is that we tried rebooting the host (via Administrator Portal) and it didn't help. We even tried removing and re-adding the host in Administrator Portal but to no avail. Additionally, the host refused to go into Maintenance mode so we had to enforce it by manually updating Engine DB. We also tried reinstalling the host via Administrator Portal and ran into another weird problem, which I'm not sure if it's a related one or a problem that deserves a dedicated discussion thread but, basically, the underlying Ansible playbook exited with the following error message: "stdout" : "fatal: [10.10.10.176]: UNREACHABLE! => {\"changed\": false, \"msg\": \"Data could not be sent to remote host \\\"10.10.10.176\\\". Make sure this host can be reached over ssh: \", \"unreachable\": true}", Counterintuitively, just before running Reinstall via Administrator Portal we had been able to reboot the same host (which as you know oVirt does via Ansible as well). So, no changes on the host in between just different Ansible playbooks. To confirm that we actually had access to the host over ssh we successfully ran ssh -p $PORT root(a)10.10.10.176 -i /etc/pki/ovirt-engine/keys/engine_id_rsa and it worked. That made us scratch our heads for a while but what seems to had fixed Ansible's ssh access problems was manual full stop of all VDSM-related systemd services on the host. It was just a wild guess but as soon as we stopped all VDSM services Ansible stopped complaining about not being able to reach the target host and successfully did its job. I'm sure you'd like to see more logs but I'm not certain what exactly is relevant. There are a ton of logs as this deployment is comprised of nearly 80 hosts. So, I guess it's best if you just request to see specific logs, messages or configuration details and I'll cherry-pick what's relevant. We don't really understand what's going on and would appreciate any help. We tried just about anything we could think of to resolve this issue and are running out of ideas what to do next. If you have any questions just ask and I'll do my best to answer them.

Unable to enable HPET component of an specific VM in oVirt 4.7
by ricardoot＠gmail.com 24 Oct '23

24 Oct '23

Hello community members, I'm currently using oVirt 4.7 as my virtualization environment, and I'm facing an issue with enabling the HPET (High Precision Event Timer) component in the XML configuration file of virtual machine (VM). Upon inspecting the XML file, I noticed that the `<timer name='hpet' present='no'/>` line is missing, indicating that the HPET component is disabled. Here are the steps I have taken so far: 1. I verified that the VM's XML configuration file does not include the `<timer name='hpet' present='yes'/>` line. 2. While the VM was powered on, I used the following command to edit the XML configuration file: ``` virsh edit VM_NAME ``` I added the `<timer name='hpet' present='yes'/>` line to the XML file. However, the changes did not persist after restarting the VM. To provide additional information, on the host where oVirt is running, the available clock sources can be viewed by executing the following command: ``` cat /sys/devices/system/clocksource/clocksource0/available_clocksource ``` The output shows the available clock sources, such as `tsc`, `hpet`, and `acpi_pm`. To resolve the authentication issue with the `virsh` command, I created a user with appropriate privileges using the following command: ``` sudo saslpasswd2 -a libvirt USERNAME ``` After creating the user, I was able to authenticate successfully with the `virsh` command using the newly created credentials. However, I'm unable to find an option to add the HPET parameter in the web console of oVirt. It seems that the option to configure HPET is not available in the web console. Has anyone else encountered a similar issue in oVirt 4.7? Could you please provide guidance or suggest a solution to enable the HPET component in the XML configuration file of a powered-off VM in oVirt 4.7? Any insights, experiences, or suggestions would be greatly appreciated. Thank you in advance for your assistance! Best regards,

Processors compatibility matrix oVirt
by Jorge Visentini 21 Jul '23

Do you have any documentation or compatibility matrix between oVirt and processors? How can I know if a processor is compatible? I ask because in the *lscpu* command I see 2 sockets, but in the *engine* I only see 1 socket. BR. -- Att, Jorge Visentini +55 55 98432-9868

ovirt with rocky linux kvm
by cynthiaberbery＠outlook.com 21 Jul '23

21 Jul '23

Hello, after installing multiple machines as rocky linux, Ovirt was chosen to be used to manage this infra. But adding these machines as "hosts" on ovirt always give: Error while executing action: Cannot add Host. Connecting to host via SSH has failed, verify that the host is reachable (IP address, routable address etc.) You may refer to the engine.log file for further details. Is rocky kvm supported on ovirt 4.3.10.4-1.el7? Do you have any contact with a supporting company/team for ovirt to check their support plan?
