How to configure HA virtual machine on hosts without IPMI
by samuel.xhu＠horebdata.cn 12 Oct '22

12 Oct '22

Dear Ovirt folks, I am thinking of deploly an experimental Ovirt 3-node Cluster on servers without IPMI. As far i know, Ovirts needs each host to have fence agent working for any HA virtual machine. My question is, are there any other ways in Ovirt to support fencing without using IPMI? thanks a lot, Samuel Do Right Thing (做正确的事) / Pursue Excellence (追求卓越) / Help Others Succeed (成就他人)

Re: OVS Task Error when Add EL Host

Hi, I'm having the exact same problem doing a fresh install of RHEL and setting up (command line: hosted-engine --deploy --4) the ovirt-engine. I assume it must have been some kind of update to the base OS - (in my case RHEL 8.6 (Ootpa), because i have done previous installations with this exact OS and centos-release-ovirt45 repos without having an issues. The failed task is: TASK [ovirt.ovirt.hosted_engine_setup : Wait for the host to be up] and, on the hosted-engine log: /var/log/ovirt-hosted-engine-setup/engine-logs-2022-10-11T18:43:29Z/log/ovirt-engine/host-deploy I see: "stdout" : "fatal: [xxxxx]: FAILED! => {\"msg\": \"The conditional check 'cluster_switch == \\\"ovs\\\" or (ovn_central is defined and ovn_central | ipaddr)' failed. The error was: The ipaddr filter requires python's netaddr be installed on the ansible controller\\n\\nThe error appears to be in '/usr/share/ovirt-engine/ansible-runner-service-project/project/roles/ovirt-provider-ovn-driver/tasks/configure.yml': line 3, column 5, but may\\nbe elsewhere in the file depending on the exact syntax problem.\\n\\nThe offending line appears to be:\\n\\n- block:\\n - name: Install ovs\\n ^ here\\n\"}",

SSL error on oVirt 4.2.4

Hello I have oVirt cluster with 25 hypervisors that has been running fine for a couple of years and today all of a sudden engine was getting ssl errors talking to the hypervisors. Error in engine.log is: 2022-10-10 16:20:23,562-05 ERROR [org.ovirt.engine.core.vdsbroker.monitoring.HostMonitoring] (EE-ManagedThreadFactory-engineScheduled-Thread-47) [] Unable to RefreshCapabilities: VDSNetworkException: VDSGenericException: VDSNetworkException: Received fatal alert: unknown_ca Certificates don't seem expired and I ran the command: openssl x509 -noout -in /etc/pki/ovirt-engine/ca.pem -fingerprint openssl x509 -noout -in /etc/pki/vdsm/certs/cacert.pem -fingerprint # openssl x509 -noout -in /etc/pki/vdsm/libvirt-spice/ca-cert.pem -fingerprint # openssl x509 -noout -in /etc/pki/vdsm/libvirt-vnc/ca-cert.pem -fingerprint # openssl x509 -noout -in /etc/pki/CA/cacert.pem -fingerprint Those commands show that the fingerprints are the same. openssl verify -CAfile /etc/pki/ovirt-engine/ca.pem /etc/pki/ovirt-engine/certs/engine.cer # openssl verify -CAfile /etc/pki/ovirt-engine/ca.pem /etc/pki/ovirt-engine/certs/apache.cer # openssl verify -CAfile /etc/pki/ovirt-engine/ca.pem /etc/pki/ovirt-engine/certs/websocket-proxy.cer # openssl verify -CAfile /etc/pki/ovirt-engine/ca.pem /etc/pki/ovirt-engine/certs/jboss.cer # openssl verify -CAfile /etc/pki/ovirt-engine/ca.pem /etc/pki/ovirt-engine/certs/imageio-proxy.cer # openssl verify -CAfile /etc/pki/ovirt-engine/ca.pem /etc/pki/ovirt-engine/certs/ovirt-provider-ovn.cer These verification commands come back as OK. I am having trouble finding my problem. Does anyone have any suggestions? I am not finding any hits on google and unknown_ca. Also the vdsm log on hypervisors has this: 2022-10-10 15:54:42,843-0500 ERROR (Reactor thread) [ProtocolDetector.SSLHandshakeDispatcher] ssl handshake: SSLError, address: ::ffff:192.168.50.26 (sslutils:263) Thanks Don

Convert raw images to qcow format
by Jonas 11 Oct '22

11 Oct '22

Hi there I want to create incremental backups of a few imported VMs, but the VM disks are in the raw disk format which does not support incremental backup. Is there a way to convert existing disks from raw to qcow in oVirt? Since qemu-img can do this,I assume there must be a way.. Thank you Jonas

Pre-Installing OpenVSwitch For oVirt Self-Hoster Install - Issues?
by Matthew J Black 11 Oct '22

11 Oct '22

Hi All, Is anyone aware of any issues (ie "gotchas") with pre-installing OpenVSwitch in preparation for an oVirt Self-Hosted install? We're trying to work around an error we're getting with `hosted-engine --deploy` which spits out: `error: Failed to start network default\nerror: internal error: Network is already in use by interface bond1.a`. What we're thinking is if we pre-create the OVS Network (ie ovirtmgmt) then `hosted-engine --deploy` won't baulk and fail to install. We've been grinding away at this and other issues for several weeks now and we're getting pretty desperate at this stage, to the point that we're starting to seriously consider giving up on oVirt completely - which would be a shame because it seems to be made for the job we want to do, but if we can't get it installed, let along working, then what's the point? (Plus I hate the thought of all the wasted time and effort - but that may just be the "suck cost fallacy" at work). Anyway, if anyone has any insights we'd appreciate them. Cheers Dulux-Oz

Re: OVS Task Error when Add EL Host
by Łukasz Pelczyk 09 Oct '22

I just hit the same error. Initially I got it on the beginning of installation (both netaddr and jmespath were not found). Seems that python3.9 is used so initially I solved it via pip3.9 install. Alternatively you can get the rpm packages from epel. The same issues is on ovirt VM side. As a workaround I started deployment with pause (hosted-engine --deploy --ansible-extra-vars=he_pause_host=true). With that you can ssh to the instance, and manually run pip install which got me: 'Successfully installed jmespath-1.0.1 netaddr-0.8.0'. This is just a workaround and proper fix should be reflected in engine VM image, or on the repos side.

Hi, please try to downgrade ansible-core-2.13 to 2.12, oVirt doesn't support 2.13 on EL8 yet.

Question: How does ovirt storage domain differ from VMFS?
by jstk888＠gmail.com 07 Oct '22

07 Oct '22

Hello, I was asked the other day what file system oVirt uses to store virtual machine images and how it differed from VMware VMFS. I had to admit that I didn't quite understand this aspect of oVirt. I've had a look around but haven't found an answer. I was wondering if someone could explain at a high level, how the underlying oVirt VM storage domain differs from VMFS? What file system is used? Does it use a file system at all? Thank you.
