Ovirt CSI driver
by Nathanaël Blanchet 03 May '23

03 May '23

Hello, According to https://docs.openshift.com/container-platform/4.11/storage/container_storag… Ovirt CSI driver doesn't support snapshots. This is annoying because we can't backup Persistent Volume. Is there a technical reason for that? Can we hope any development for this?

Hi, Could somebody comment on storage options i.e Gluster or Ceph and when to use each one? Looking for an architecture which is fully redundant, both at the hypervisor level and at the storage level so needs to include data replication. thx

VDSM certs expired, manual renewal not working
by cen 02 May '23

02 May '23

Hi Our VDSM certs have expired, both hosts are unassigned and can't be put into maintenance from UI. vdsm-client is not working, times out even with --insecure flag. Does host and port need to be specified when run locally or should defaults work? Error in console events is: Get Host Capabilities Failed: PKIX path validation failed... I followed a RHV guide for this exact situation and generated new vdsm certificate using the ovirt-engine CA. The new cert seems identical to the old one, everything matches (algos, extensions, CA, CN, SAN etc) just new date. After restarting libvirtd and vdsmd on the host with new cert in place the host is still not reachable. However, error message is now slightly different: get Host Capabilities failed: Received fatal error: certificate_expired Cert was replaced in the following locations: /etc/pki/vdsm/certs/vdsmcert.pem /etc/pki/vdsm/libvirt-spice/server-cert.pem /etc/pki/libvirt/clientcert.pem Is there another location missing? What else can I try? All help appreciated in advance

checking engine vm status during global maintenance
by Alexey Valkov 02 May '23

02 May '23

Hi all, I tried to check engine status (via hosted-engine --vm-status) during global maintenance in oVirt 4.5.1 and discovered that it showed me status as it was just before entering global maintenance. Is it by design? And HA agent doesn't monitor and therefore doesn't update Engine VM status? If I remember right in oVirt 4.2 hosted-engine --vm-status showed correct status of Engine VM regardless of Global maintenance. I shutted down the engine but the output of hosted-engine --vm-status was Engine status : {"vm": "up", "health": "good", "detail": "Up"} Notice !! Cluster is in GLOBAL MAINTENANCE mode !! existed in the output. Host timestamp and extra metadata was up to date. All rest info looked good. Thi is my second attempt to ask the question (first was at 24/04 and still is being moderated). -- Best regards Alexei

Disable SSL for ovirt-ha-broker?
by phil.gardnerjr＠gmail.com 02 May '23

02 May '23

I have a neglected oVirt 4.3 cluster that consists of two hosts with a hosted engine. Unfortunately, the host SSL certificates on both hosts are expired, and now the hosted engine is down from a power loss event. I don't see a way to get ovirt-ha-broker functioning again if the vdsm certificates are expired, since I can't get the hosted engine VM to start in order to generate new host certificates. My sledgehammer approach was to just disable SSL in the configuration for vdsm and libvirt, but I can't seem to figure out how to disable SSL for ovirt-ha-broker. Is this possible? I don't know what else to try. I figure if I can just get the hosted-engine back up, and I can maybe proceed with getting one of the hosts back up and functional in some way, and maybe getting the single VM that I am concerned about started up. If the hosted engine isn't recoverable, is it possible to get another VM up and running with just standard kvm/libvirt/virsh if I still have access to the storage?

Serial console VMs (vmconsole) only listed when admin user is logged into Manager WebUI?
by aleblanc＠lbl.gov 28 Apr '23

28 Apr '23

I am running a test\POC oVirt configuration with the following... oVirt engine: ovirt-engine-4.5.4-1.el8 engine OS: Rocky Linux release 8.7 (Green Obsidian) install type: stand-alone engine install I am able to access the serial console of VMs successfully, using the proper SSH command directly on the engine or remotely. Problem is, the VMs only show up in the list IF the 'admin' or 'admin@ovirt' user is presently logged into the manager UI. If I log out of the manager UI, the serial console returns 'no VMs'. Is there a setting or something that I am missing? ==== logged out of manager UI: [ovirt-vmconsole-proxy-helper]# /usr/libexec/ovirt-vmconsole-proxy-helper/ovirt-vmconsole-list.py --version "1" consoles --entityid "d55e4ab6-0318-46b0-95bc-12b21144eb88" {"consoles": [], "version": 1, "content": "console_list"} ==== logged into manager UI: [ovirt-vmconsole-proxy-helper]# /usr/libexec/ovirt-vmconsole-proxy-helper/ovirt-vmconsole-list.py --version "1" consoles --entityid "d55e4ab6-0318-46b0-95bc-12b21144eb88" {"consoles": [{"console": "3ecd0eda-130d-434b-9ece-32bbcc3b3e5a.sock", "vmid": "3ecd0eda-130d-434b-9ece-32bbcc3b3e5a", "host": "dldvovirt01", "vmname": "mytestvm_2", "vm": "mytestvm_2"}, {"console": "4e6abfbe-ede3-4e87-8d07-4ed1d6cb715c.sock", "vmid": "4e6abfbe-ede3-4e87-8d07-4ed1d6cb715c", "host": "dldvovirt02", "vmname": "testvm_4", "vm": "testvm_4"}, {"console": "dc4d017b-4f68-4eee-b80e-e49122345139.sock", "vmid": "dc4d017b-4f68-4eee-b80e-e49122345139", "host": "dldvovirt01", "vmname": "mytestvm_3", "vm": "mytestvm_3"}], "version": 1, "content": "console_list"} Any help would be appreciated.

Getting to the consoles of the Virtual machines
by destfinal＠googlemail.com 28 Apr '23

28 Apr '23

Hi, I have just deployed a functional oVirt cluster. I have created a few virtual machines and am able to ssh into them. However, I could not connect to the consoles of any of the running virtual machines. If I click on the console, from the management portal, it offers me to download a console.vv file. If I download it and double click on it, the file (console.vv itself) simply disappears. I connected to the kvm of the the node where the vm is running, from a VMM (from my local machine which is a Ubuntu 22.04) and when I tried to open the the console from there I get a "Viewer was disconnected" message in the machine Window. In the oVirt cluster, the VM console settings are: Video Type: VGA # Another available option is QXL Graphics protocol: VNC # Which is the only option available Could not find any useful information from the engin.log (all it say is that "Initiated console session for VM XXXXXX). What setting should I enable/change to get into the cnsole of my VM's? Please let me know if you need more information in this regard. Thanks

oVirt Self-hosted Engine Deployment fails
by destfinal＠googlemail.com 28 Apr '23

28 Apr '23

Hi, I am struggling to get an oVirt cluster setup (for a PoC with some workstations) for the past more than one week and am getting nowhere. Following is my environment: Machine: Dell Workstation with i7, 16G RAM, 256G (I have got couple of more of this machine but could not getr beyond the first one) OS: oVirt minimal (https://resources.ovirt.org/pub/ovirt-4.5/iso/ovirt-node-ng-installer/4.5.4…) Documentation followed: https://www.ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engin… Cluster name chosen: my.cluster First node host name: node1-ovirt.my.cluster Engine VM name: ovirt-engine.my.cluster The documentation states that there should be resolvable DNS entries for both the oVirt hosts *as well as* for the oVirt engine VM. I am a bit confused on this as the VM will get a DHCP address only after running the 'hosted-engine' script. What ip address should I have for the engine VM (say if I have my engine host name as ovirt-engine.my.cluster)? If I have no entry for the engine in the DNS I get the following error: [ ERROR ] Host name is not valid: ovirt-engine.my.cluster did not resolve into an IP address Please provide the FQDN you would like to use for the engine. Note: This will be the FQDN of the engine VM you are now going to launch, it should not point to the base host or to any other existing machine. Engine VM FQDN: So I simply added an entry for 'ovirt-engine.my.cluster' with a dummy value 192.168.0.222 (this is an ip address on the host subnet; but the engine gets a DHCP address from a different subnet from a virtual network from the host; I dont understand this) which moves away from the above problem and goes all the way (after providing the values for a few other questions) to hang at 'Wait for the host to be up' for a while and eventually fail with an error message: [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Host is not up, please check logs, perhaps also on the engine machine"} At this point a vm is running in the host. I logged on to the VM and searched the logs and found the following line in the /var/log/ovirt-engine/engine.log: ERROR [org.ovirt.engine.core.common.utils.ansible.AnsibleExecutor] (EE-ManagedThreadFactory-engine-Thread-1) [728b2edd-d13a-48c3-a2c1-42a66a5334c5] Exception: Task Install ovs failed to execute.
