Processors compatibility matrix oVirt
by Jorge Visentini 21 Jul '23

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?

How to re-enroll a host with an active workload whose certificate expired
by David Johnson 20 Jul '23

20 Jul '23

Good evening all, I have a three host installation with a separate dedicated bare metal system for the engine, running Ovirt 4.5.2.4-1.el8. This afternoon, the engine lost communication with one of the hosts. The engine log says the certificate is expired. The official solution appears to be to put the host into maintenance mode then re-enroll it. Unfortunately, because the certificate is expired, the engine cannot switch to maintenance mode or control the VM's to shut them down. Error while executing action: Cannot switch Host to Maintenance mode. Host still has running VMs on it and is in Non Responsive state. See log excerpt below What is the correct way to update/reinstate a certificate in a running cluster when the engine does not acknowledge the host is operational due to an expired certificate? Thank you. *David Johnson* Log excerpt: 2023-07-20 16:27:46,904-05 INFO [org.ovirt.vdsm.jsonrpc.client.reactors.ReactorClient] (SSL Stomp Reactor) [] Connecting to /192.168.2.18 2023-07-20 16:27:46,904-05 INFO [org.ovirt.vdsm.jsonrpc.client.reactors.ReactorClient] (SSL Stomp Reactor) [] *Connected to /192.168.2.18:54321 <http://192.168.2.18:54321>* 2023-07-20 16:27:46,912-05 ERROR [org.ovirt.vdsm.jsonrpc.client.reactors.Reactor] (SSL Stomp Reactor) [] *Unable to process messages Received fatal alert: certificate_expired* 2023-07-20 16:27:46,914-05 ERROR [org.ovirt.engine.core.vdsbroker.monitoring.HostMonitoring] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-52) [] Unable to RefreshCapabilities: VDSNetworkException: VDSGenericException: VDSNetworkException: Received fatal alert: certificate_expired 2023-07-20 16:27:47,356-05 ERROR [org.ovirt.engine.core.vdsbroker.monitoring.HostMonitoring] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-34) [] Unable to RefreshCapabilities: ClientConnectionException: SSL session is invalid 2023-07-20 16:27:47,356-05 WARN [org.ovirt.engine.core.bll.lock.InMemoryLockManager] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-34) [] Trying to release exclusive lock which does not exist, lock key: 'f69d35b2-7666-4ac6-8645-2f119cf2ce1cVDS_INIT' 2023-07-20 16:27:47,356-05 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.GetCapabilitiesAsyncVDSCommand] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-34) [] Command 'org.ovirt.engine.core.vdsbroker.vdsbroker.GetCapabilitiesAsyncVDSCommand' return value 'org.ovirt.engine.core.vdsbroker.vdsbroker.VDSInfoReturn@7d03f4f0' 2023-07-20 16:27:47,356-05 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.GetCapabilitiesAsyncVDSCommand] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-34) [] HostName = ovirt-host-03 2023-07-20 16:27:47,356-05 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.GetCapabilitiesAsyncVDSCommand] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-34) [] Command 'GetCapabilitiesAsyncVDSCommand(HostName = ovirt-host-03, VdsIdAndVdsVDSCommandParametersBase:{hostId='f69d35b2-7666-4ac6-8645-2f119cf2ce1c', vds='Host[ovirt-host-03,f69d35b2-7666-4ac6-8645-2f119cf2ce1c]'})' execution failed: org.ovirt.vdsm.jsonrpc.client.ClientConnectionException: *SSL session is invalid*

First time user/setup
by jmred88＠gmail.com 20 Jul '23

Could someone explain to me the proper documentation I should be using for a standalone setup? I have one host with local storage/resources and would like that to both host and manage my VMs but I keep getting into the weeds with which documentation to follow.

Hi. I'm following the release of the 4.5.5 isos and I see that new isos are coming out almost every day. Is there any place where I can keep track of the changes that were made from one iso to another? Is it open for us to follow? Cheers! -- Att, Jorge Visentini +55 55 98432-9868

Hi. I am testing oVirt 4.5.5-0.master.20230712143502.git07e865d650.el8. I missed the python scripts to download and upload discs and images... Will it still be possible to use them or should I consider using Ansible? BR. -- Att, Jorge Visentini +55 55 98432-9868

oVirt 4.4. Engine Deployment: Problems with Gluster Storage Domain
by Thyen, Niko 18 Jul '23

18 Jul '23

Hi everybody! I am having a hard time getting oVirt 4.4 to work. We want to update our 4.3 Cluster and i am trying to set up a fresh 4.4 Cluster (and restore the backup later on) in order to update to 4.5. It fails at the end of the engine deloyment, when the Gluster Storage Domain should be added. I installed oVirt Node 4.4.10 on an old PC and made the following modifications to the engine deployment process: - altered defaults in /usr/share/ansible/collections/ansible_collections/ovirt/ovirt/roles/hosted_engine_setup/defaults/main.yml: - "he_pause_before_engine_setup: true" (in this pause before engine setup, i ssh into the engine and exclude the package postgresql-jdbc from update, which otherwise breaks the deployment [1]) - "he_remove_appliance_rpm: false" (to avoid the large download every single try, i tried a lot) - "he_force_ip4: true" (to avoid problems with IPv6, see below) - in /usr/share/ansible/collections/ansible_collections/ovirt/ovirt/roles/hosted_engine_setup/tasks/fetch_host_ip.yml i added after "- name: Get host address resolution:" the following lines (to avoid a problem with an "invalid" IPv6-Adress, which otherwise breaks the deployment [2]): - name: Get host IP addresses ansible.builtin.command: hostname -I register: hostname_addresses_output changed_when: true Most times, i started deployment via shell but tried via webinterface of the node as well. It fails at the task "Add glusterfs storage domain" with the following message: "[ ERROR ] ovirtsdk4.Error: Fault reason is "Operation Failed". Fault detail is "[Failed to fetch Gluster Volume List]". HTTP response code is 400." (See also [3]) When the setup asks for storage, i tried different answers (gluster.local:/volume, gluster.local:/path/to/brick/volume, 192.168.8.51:/volume ...), no mount options. I added firewall rules for glusterfs at node and engine. Even tried disabling the firewall. No firewall on the gluster servers running. On the Node, i also tested setting SELinux to permissive. Recorded the traffic at different interfaces ("ovirtmgmt" and "virbr0" on the node and "eth0" on the engine) and i can see the node and the gluster server talking: Node gets the volume with options (which are, btw, compliant to the docs, "storage.owner-gid: 36" "storage.owner-uid: 36" etc) but thats it, no further packets to mount the volume. I noticed some ARP packets as well, the node asks the IP from the engine (the configured static IP, which is not yet active). And the engine sends a dns request for the gluster server to the node (via interface virbr0), but doesnt connect to the gluster server. At least, thats what i can see, most of the traffic is TLS, which i couldnt decrypt yet. I appreciate any hint where to find the right keys. Anyway, i can ssh from the engine to the gluster server and mount the gluster volume manually on the node (mount -t glusterfs gluster.local:/volume /local/path), so there seem no connectivity issues. Since the engine deployment log is around 30MB i attached a log summary with findings i found relevant. I'll provide more logs if needed. I really wanna put this huge timesink to an end. Can anyone help me or point me in the right direction? Many thanks in advance :) Regards, Niko [1] This was the error message i got: "[ ERROR ] fatal: [localhost -> 192.168.222.195]: FAILED! => {"attempts": 30, "changed": false, "connection": "close", "content": "Error500 - Internal Server Error", "content_encoding": "identity", "content_length": "86", "content_type": "text/html; charset=UTF-8", "date": "Wed, 17 May 2023 22:42:27 GMT", "elapsed": 0, "msg": "Status code was 500 and not [200]: HTTP Error 500: Internal Server Error", "redirected": false, "server": "Apache/2.4.37 (centos) OpenSSL/1.1.1k mod_auth_gssapi/1.6.1 mod_wsgi/4.6.4 Python/3.6", "status": 500, "url": "http://localhost/ovirt-engine/services/health"}" [2] This was the error message i got: "VDSM ovirt.martinwi.local command HostSetupNetworksVDS failed: Internal JSON-RPC error: {'reason': "Invalid IP address: 'fe80::ea3f:67ff:fe7f:a029%ovirtmgmt' does not appear to be an IPv4 or IPv6 address"}" [3] /var/log/ovirt-hosted-engine-setup/ovirt-hosted-engine-setup-20230718140628-rryscj.log: 2023-07-18 16:32:35,877+0200 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:106 {'msg': 'Fault reason is "Operation Failed".

Local physical disk directly on the VM
by Jorge Visentini 17 Jul '23

17 Jul '23

Hi. Is it possible to deliver a physical disk straight to the VM? What's my idea... I have a local disk on the server and I want to deliver it directly to a VM, is it possible? For example, take the hypervisor disk /dev/disk/by-id/ata-INTEL_SSDSC2KB480G8_PHYF117203AA480BGN and hand it to the VM. BR. -- Att, Jorge Visentini +55 55 98432-9868
