Deploy oVirt Engine fail behind proxy
by Matteo Bonardi 21 Mar '24

Hi, I am trying to deploy the ovirt engine following self-hosted engine installation procedure on documentation. Deployment servers are behind a proxy and I have set it in environment and in yum.conf before run deploy. Deploy fails because ovirt engine vm cannot resolve AppStream repository url: [ INFO ] TASK [ovirt.engine-setup : Install oVirt Engine package] [ ERROR ] fatal: [localhost -> ovirt-manager.mydomain]: FAILED! => {"changed": false, "msg": "Failed to download metadata for repo 'AppStream': Cannot prepare internal mirrorlist: Curl error (6): Couldn't resolve host name for http://mirrorlist.centos.org/?release=8&arch=x86_64&repo=AppStream&infra=st… [Could not resolve host: mirrorlist.centos.org]", "rc": 1, "results": []} [ ERROR ] Failed to execute stage 'Closing up': Failed executing ansible-playbook [ INFO ] Stage: Clean up [ INFO ] Cleaning temporary resources [ INFO ] TASK [ovirt.hosted_engine_setup : Execute just a specific set of steps] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.hosted_engine_setup : Force facts gathering] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.hosted_engine_setup : Fetch logs from the engine VM] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.hosted_engine_setup : Set destination directory path] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.hosted_engine_setup : Create destination directory] [ INFO ] changed: [localhost] [ INFO ] TASK [ovirt.hosted_engine_setup : include_tasks] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.hosted_engine_setup : Find the local appliance image] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.hosted_engine_setup : Set local_vm_disk_path] [ INFO ] skipping: [localhost] [ INFO ] TASK [ovirt.hosted_engine_setup : Give the vm time to flush dirty buffers] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.hosted_engine_setup : Copy engine logs] [ INFO ] TASK [ovirt.hosted_engine_setup : include_tasks] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.hosted_engine_setup : Remove local vm dir] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.hosted_engine_setup : Remove temporary entry in /etc/hosts for the local VM] [ INFO ] changed: [localhost] [ INFO ] TASK [ovirt.hosted_engine_setup : Clean local storage pools] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.hosted_engine_setup : Destroy local storage-pool {{ he_local_vm_dir | basename }}] [ INFO ] TASK [ovirt.hosted_engine_setup : Undefine local storage-pool {{ he_local_vm_dir | basename }}] [ INFO ] TASK [ovirt.hosted_engine_setup : Destroy local storage-pool {{ local_vm_disk_path.split('/')[5] }}] [ INFO ] TASK [ovirt.hosted_engine_setup : Undefine local storage-pool {{ local_vm_disk_path.split('/')[5] }}] [ INFO ] Generating answer file '/var/lib/ovirt-hosted-engine-setup/answers/answers-20201109165237.conf' [ INFO ] Stage: Pre-termination [ INFO ] Stage: Termination [ ERROR ] Hosted Engine deployment failed: please check the logs for the issue, fix accordingly or re-deploy from scratch.

Cannot restart ovirt after massive failure.
by Gilboa Davara 18 Jan '24

18 Jan '24

Hello all, During the night, one of my (smaller) setups, a single node self hosted engine (localhost NFS) crashed due to what-looks-like a massive disk failure (Software RAID6, with 10 drives + spare). After a reboot, I let the RAID resync with a fresh drive) and went on to start oVirt. However, no such luck. Two issues: 1. ovirt-ha-broker fails due to broken hosted engine state (log attached). 2. ovirt-ha-agent fails due to network test (tcp) even though both remote-host and DNS servers are active. (log attached). Two questions: 1. Can I somehow force the agent to disable the network liveliness test? 2. Can I somehow force the broker to rebuild / fix the hosted engine state? - Gilboa

how to renew expired ovirt node vdsm cert manually ?

below are the steps to renew the expired vdsm cert of ovirt node # To check CERT expired # openssl x509 -in /etc/pki/vdsm/certs/vdsmcert.pem -noout -dates 1. Backup vdsm folder # cd /etc/pki # mv vdsm vdsm.orig # mkdir vdsm ; chown vdsm:kvm vdsm # cd vdsm # mkdir libvirt-vnc certs keys libvirt-spice libvirt-migrate # chown vdsm:kvm libvirt-vnc certs keys libvirt-spice libvirt-migrate 2. Regenerate cert & keys # vdsm-tool configure --module certificates 3. Copy the cert to destination location chmod 440 /etc/pki/vdsm/keys/vdsmkey.pem chown root /etc/pki/vdsmcerts/*pem chmod 644 /etc/pki/vdsmcerts/*pem cp /etc/pki/vdsm/certs/cacert.pem /etc/pki/vdsm/libvirt-spice/ca-cert.pem cp /etc/pki/vdsm/keys/vdsmkey.pem /etc/pki/vdsm/libvirt-spice/server-key.pem cp /etc/pki/vdsm/certs/vdsmcert.pem /etc/pki/vdsm/libvirt-spice/server-cert.pem cp /etc/pki/vdsm/certs/cacert.pem /etc/pki/vdsm/libvirt-vnc/ca-cert.pem cp /etc/pki/vdsm/keys/vdsmkey.pem /etc/pki/vdsm/libvirt-vnc/server-key.pem cp /etc/pki/vdsm/certs/vdsmcert.pem /etc/pki/vdsm/libvirt-vnc/server-cert.pem cp -p /etc/pki/vdsm/certs/cacert.pem /etc/pki/vdsm/libvirt-migrate/ca-cert.pem cp -p /etc/pki/vdsm/keys/vdsmkey.pem /etc/pki/vdsm/libvirt-migrate/server-key.pem cp -p /etc/pki/vdsm/certs/vdsmcert.pem /etc/pki/vdsm/libvirt-migrate/server-cert.pem chown root:qemu /etc/pki/vdsm/libvirt-migrate/server-key.pem cp -p /etc/pki/vdsm.orig/keys/libvirt_password /etc/pki/vdsm/keys/ mv /etc/pki/libvirt/clientcert.pem /etc/pki/libvirt/clientcert.pem.orig mv /etc/pki/libvirt/private/clientkey.pem /etc/pki/libvirt/private/clientkey.pem.orig mv /etc/pki/CA/cacert.pem /etc/pki/CA/cacert.pem.orig cp -p /etc/pki/vdsm/certs/vdsmcert.pem /etc/pki/libvirt/clientcert.pem cp -p /etc/pki/vdsm/keys/vdsmkey.pem /etc/pki/libvirt/private/clientkey.pem cp -p /etc/pki/vdsm/certs/cacert.pem /etc/pki/CA/cacert.pem 3. cross check the backup folder /etc/pki/vdsm.orig vs /etc/pki/vdsm # refer to /etc/pki/vdsm.orig/*/ and set the correct owner & group permission in /etc/pki/vdsm/*/ 4. restart services # Make sure both services are up systemctl restart vdsmd libvirtd

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?

4.4.9 -> 4.4.10 Cannot start or migrate any VM (hotpluggable cpus requested exceeds the maximum cpus supported by KVM)
by Jillian Morgan 11 Apr '23

11 Apr '23

After upgrading the engine from 4.4.9 to 4.4.10, and then upgrading one host, any attempt to migrate a VM to that host or start a VM on that host results in the following error: Number of hotpluggable cpus requested (16) exceeds the maximum cpus supported by KVM (8) While the version of qemu is the same across hosts, ( qemu-kvm-6.0.0-33.el8s.x86_64), I traced the difference to the upgraded kernel on the new host. I have always run elrepo's kernel-ml on these hosts to support bcache which RHEL's kernel doesn't support. The working hosts still run kernel-ml-5.15.12. The upgraded host ran kernel-ml-5.17.0. In case anyone else runs kernel-ml, have you run into this issue? Does anyone know why KVM's KVM_CAP_MAX_VCPUS value is lowered on the new kernel? Does anyone know how to query the KVM capabilities from userspace without writing a program leveraging kvm_ioctl()'s? Related to this, it seems that ovirt and/or libvirtd always runs qmu-kvm with an -smp argument of "maxcpus=16". This causes qemu's built-in check to fail on the new kernel which is supporting max_vpus of 8. Why does ovirt always request maxcpus=16? And yes, before you say it, I know you're going to say that running kernel-ml isn't supported. -- Jillian Morgan (she/her) 🏳️‍⚧️ Systems & Networking Specialist Primordial Software Group & I.T.

oVirt host deploy: disable multipath

https://bugzilla.redhat.com/show_bug.cgi?id=1472356 There are 2 drives in my install that oVirt is claiming as multipath. I have tried blacklisting at /etc/multipath/ but that hasn't worked. Any better solutions? I need these 2 drives to be non-multipathed.

Hi, I have a 3-node oVirt cluster. I have configured 2 logical networks: ovirtmgmt and public.
