Instability after update
by Andrea Chierici 09 Jan '22

09 Jan '22

Cheers, I am in trouble... I am running an ovirt manager v4.4.9.5-1.el8. This week I updated all the hosts to latest release (starting from repo ovirt-release44-4.4.9.3-1.el8.noarch) since I hadn't done that when I upgraded the manager. Before that the system was rock solid. Unfortunately, after the upgrade, I get frequent errors on running VMs: VM XXXXXXXX is down with error. Exit message: Lost connection with qemu process. I can't get any hint from the logs, I wonder if someone has any idea of what is going on. Thanks, Andrea -- Andrea Chierici - INFN-CNAF Viale Berti Pichat 6/2, 40127 BOLOGNA Office Tel: +39 051 2095463 SkypeID ataruz --

Unrecoverable NMI error on HP Gen8 hosts.
by Diggy Mc 08 Jan '22

08 Jan '22

I have oVirt Node v4.4.8.3 running on several HP ProLiant Gen8 servers. I receive the following error under certain circumstances: "An Unrecoverable System Error (NMI) has occurred (iLO application watchdog timeout NMI, Service Information: 0x0000002B, 0x00000000)" When a host starts taking a load (but nowhere near a threshold), I encounter the above iLO-logged error and the host locks-up. I have had to grossly under-utilize my hosts to avoid this problem. I'm hoping for a better fix or work-around. I've had the same problem beginning with my oVirt 4.3.x hosts, so it isn't oVirt version specific. The little information I could find on the error wasn't helpful. Red Hat acknowledges the issue, but limited to shutdown/reboot operations; not during "normal" operations. Anyone else experienced this problem? How did you fix it or work around it? I'd like to better utilize my servers if possible. In advance, thank you to anyone and everyone who offers help.

Hi everyone, I would like via API, or. pull information about I / O usage by individual servers directly from the postre database. But I have a data warehouse turned off for performance reasons. Is this information collected somewhere so that I can collect it from somewhere in my external database or read it from the virus database? Thanks for the information.

sanlock issues after 4.3 to 4.4 migration

w2k19 runOnce GuestTools ISO missing
by hellweiss 06 Jan '22

06 Jan '22

Hello List, I've latest ovirt Node on the Servers: ovirt-node-ng-4.4.9.3-0.20211215.0+1 and latest Engine 4.4.9 on CentOS Stream. When trying to run Windows 2019 Server installation from ISO with runOnce and Attach Windows Guest ISO Machine can not be started. If I remove Attach Windows Guest CD VM boots just fine. Workaround is to use VM Portal and change CD there when Windows Installer doesnt find any Disk. Latest Guest Tools ISO is installed on engine with using dnf install virtio-win in /usr /share/virtio-win I copied the Folder /usr/share/virtio-win from engine to every Node, but that also doesn't work. dnf search virtio-win on ovirt Node gives no results. What to do to get the VM with runOnce with Windows Guest Tools ISO attached to boot ? Why not let the User choose the ISO to use from the ISO Storage Domain when runOnce and Attach Windows Guest ISO is enabled ? Thanks Uli

Ovirt 4.4.9 install fails (guestfish)?
by Andy Kress 06 Jan '22

06 Jan '22

Support, Happy new year, I am trying a fresh install of ovirt (4.4.9) and seem to not be able to get past deploying the host to the glusterfs volume. I am able to mount the volume from each host and have checked the configuration of the engine volume which allows vdsm and KVM to mount. I dont know if this is a glustermount problem or guestfish as the install fails when moving the VM to the hosted storage. Attached is the install log as well as the installed packages. The specific error is genereated when the install "inject network configuration with guestfish" on install is: libguestfs: error: appliance closed the connection unexpectedly.\nThis usually means the libguestfs appliance crashed Based off the error, "relabeling" I have even attempted to disable selinux in the engine during install which produced the same error. Additionally I also downgraded Any help is appreciated. Thanks AK

Using IBM Spectrum Scale as POSIX compliant filesystem under oVirt 4.4 results in oVirt host reboot.
by Andi Nør Christiansen 03 Jan '22

03 Jan '22

Hi, Does anyone know how to mount a spectrum scale filesystem as a storage domain using the POSIX compliant storage option. I've tried to follow an earlier post about this - https://lists.ovirt.org/archives/list/users@ovirt.org/thread/LLXLSI4ZQFU32P… specifically the options provided by jtorres: Domain Function: Data Name: name_of_the_domain Storage Type: Posix Compliant FS Path: gpfs_kvm (the name of the "device"/"filesystem" created, not an absoluthe path) VFS Type: gpfs Mount Options: rw,relatime,dev=gpfs_kvm (the dev parameter is the key to mount the filesystem). Using those options, the webinterface just tells me it cannot communicate with the storage. If I change it to: Domain Function: Data Name: name_of_the_domain Storage Type: Posix Compliant FS Path: /mnt/b4tsz001 VFS Type: gpfs Mount Options: rw,relatime The oVirt host reboots immediately. I have mounted the filesystem locally on the oVirt Host under /mnt/<filesystem name> Change the owner to: vdsm:kvm Am I missing something or is this a general bug between spectrum scale and oVirt. Any ideas will be appreciated! Thanks Best Regards Andi Christiansen

Help installing oVirt on single machine, without cockpit

02 Jan '22

The reply button is taking me to a "mailto" tab again, but hopefully making the subject the same, will put this under the right thread? If not, I'm not sure how to reply on the new system. The original thread is here: https://lists.ovirt.org/archives/list/users@ovirt.org/thread/3L6EVRT4YBEJOI…, and it continues here for a bit: https://lists.ovirt.org/archives/list/users@ovirt.org/thread/C4Z65RXLFPOCS6… . @Strahil Nikolov > Have you thought about deploying HostedEngine and when you need to update the engine -> put the host in maintenance -> backup & restore The way I understand the update process, you can't update with a hosted engine unless you have two hosts. One needs to run the engine VM, so the other can go into maintenance. Is this wrong? For my use case, I'm looking for something that'll work/update on a single host. I'm trying to get the engine running next to the hypervisor, so it can run when the VM's come down. I can get the engine running on a CentOS Stream install, but it says it has 0/0 hosts running, so I don't think it can deploy VM's. I can't find a way to install the node's hypervisor package-set either. Unless that package exists, the only other idea I have for this route is doing a "hosted engine" install, but destroy the engine VM and point it to the local engine. This seems extreme to me lol. I tried setting up the engine on a node itself, but the error I can't get past yet is in the second url, top of this message. It can't start the ovirt-imageio service, because of a missing file. Happy Holidays all! Cameron

With libgfapi gone - ? - qcow2 backups
by lejeczek 31 Dec '21

31 Dec '21

hi guys Now with libgfapi support removed from qemu/libvirt - certainly in binaries from oVirt repos for CentOS 9 - how does one take qcow2 backups? Would that be some specific options to mount gluster vol in order to overcome: -> $ qemu-img convert -O qcow2 ./ubuntu.qcow2.bkp ubuntu.qcow2 qemu-img: Could not open './ubuntu-tor.qcow2.bkp': Could not open backing file: Failed to get shared "write" lock Is another process using the image [/VMs3/ubuntu.qcow2]? or perhaps 'qemu-img' can do the trick somehow? all thoughts shared are much appreciated. many thanks, L>

VMs do not run with Q35 BIOS
by Martin Marusinec 30 Dec '21

30 Dec '21

Hello, yesterday I installed new ovirt node into the existing cluster, and I found out I cannot start any of my VMs on it. After some tries, I found out the VM simply does not start up with Q35 BIOS. It starts with legacy BIOS, or Q35 UEFI, but not with Q35 BIOS. Blank screen, nothing. The node is slightly newer then others. What could I do with it? I would rather avoid changing chipset on all my VMs to legacy, just to be able to run them on new node.... Martin

Suggested upgrading path from CentOS based 4.4.8 to 4.4.9
by Gianluca Cecchi 28 Dec '21

28 Dec '21

I have a lab with an environment based on 4.4.8.6-1, with 3 CentOS Linux 8.4 hosts and a CentOS 8.4 external engine system (that is a VM on vSphere, so that I can leverage a snapshot methodology for the process...). I would like to pass to 4.4.9 and retain a full plain OS on hosts for the moment, without going through oVirt nodes, but standing the repo problems and CentOS 8.x going through EOL this is what I'm planning to do: 1. stop engine service on engine system 2. convert engine to CentOS Stream This step needs some confirmation. Could you provide an official link about the process? I'm not able to find it again. Is it a problem of mine or all (CentOS website, RHEL website) seem to point only to conversion from CentOS Linux to RHEL?? Apart external websites provided workflows, I was only able to find a mid January youtube video, when CentOS was based on 8.3, with these steps: yum install centos-release-stream yum swap centos-{linux,stream}-repos yum repolist yum distro-sync reboot The video link is here: https://www.youtube.com/watch?v=Ba2ytp_8x7s No mention at https://www.redhat.com/en/blog/faq-centos-stream-updates And on CentOS page I only found this: https://centos.org/distro-faq/ with Q7 containing only the two instructions: dnf swap centos-linux-repos centos-stream-repos dnf distro-sync What to use safely? Is it possible to include some sort of documentation or links on oVirt page, to migrate from CentOS Linux to CentOS Stream for oVirt upgrade purposes? 3. After reboot implied, I think, in step 2., use the usual steps to update engine to 4.4.9 4. update the first out of three hosts from CentOS Linux to CentOS Stream and to 4.4.9. 4.a follow the same approach of engine (when defined) and pass it to Stream retaining the 4.4.8. 4.b upgrade from the web admin gui to 4.4.9 5. Do the same for second host and third hosts Any hints, comments, limitations in having mixed 4.4.8 and 4.4.9 hosts for a while and such? Thanks, Gianluca

Unable to start ovirt-ha-agent on all hosts

Hi list! on a hyperconverged cluster with three hosts I am unable to start the ovirt-ha-agent. The history: As all three hosts were running Centos 8, I tried to upgrade host3 to Centos 8 Stream first and left all VMs and host1 and host2 untouched, basically as a test. After all migrations of VMs to host3 failed with: ``` qemu-kvm: error while loading state for instance 0x0 of device '0000:00:01.0/pcie-root-port'#0122021-12-24T00:56:49.428234Z qemu-kvm: load of migration failed: Invalid argument ``` and since I haven't had the time to dig into that, I decided to roll back the upgrade and rebooted host3 into Centos 8 again and re-installed host3 through the engine appliance. During that process (and the restart of host3) the engine appliance became unresponsive and crashed. The problem: Currently all ovirt-ha-agent services on all hosts fail with the following message in /var/log/ovirt-hosted-engine-ha/agent.log ``` MainThread::INFO::2021-12-24 03:56:03,500::agent::67::ovirt_hosted_engine_ha.agent.agent.Agent::(run) ovirt-hosted-engine-ha agent 2.4.9 started MainThread::INFO::2021-12-24 03:56:03,516::hosted_engine::242::ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine::(_get_hostname) Certificate common name not found, using hostname to identify host MainThread::INFO::2021-12-24 03:56:03,575::hosted_engine::548::ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine::(_initialize_broker) Initializing ha-broker connection MainThread::INFO::2021-12-24 03:56:03,576::brokerlink::82::ovirt_hosted_engine_ha.lib.brokerlink.BrokerLink::(start_monitor) Starting monitor network, options {'addr': 'GATEWAY_IP', 'network_test': 'dns', 'tcp_t_address': '', 'tcp_t_port': ''} MainThread::ERROR::2021-12-24 03:56:03,577::hosted_engine::564::ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine::(_initialize_broker) Failed to start necessary monitors ``` Now I've stumbled upon this one [1984262](https://bugzilla.redhat.com/show_bug.cgi?id=1984262) but it doesn't seem to apply. All hosts resolve properly, all hosts also have proper hostnames set, unique /etc/hosts entries and proper A records set (in the form of hostname.subdomain.domain.tld). The versions involved are: ``` [root@host2 ~]# rpm -qa ovirt* ovirt-hosted-engine-setup-2.5.4-2.el8.noarch ovirt-imageio-daemon-2.3.0-1.el8.x86_64 ovirt-host-dependencies-4.4.9-2.el8.x86_64 ovirt-vmconsole-1.0.9-1.el8.noarch ovirt-imageio-client-2.3.0-1.el8.x86_64 ovirt-host-4.4.9-2.el8.x86_64 ovirt-python-openvswitch-2.11-1.el8.noarch ovirt-openvswitch-ovn-host-2.11-1.el8.noarch ovirt-provider-ovn-driver-1.2.34-1.el8.noarch ovirt-openvswitch-ovn-2.11-1.el8.noarch ovirt-release44-4.4.9.2-1.el8.noarch ovirt-openvswitch-2.11-1.el8.noarch ovirt-ansible-collection-1.6.5-1.el8.noarch ovirt-openvswitch-ovn-common-2.11-1.el8.noarch ovirt-hosted-engine-ha-2.4.9-1.el8.noarch ovirt-vmconsole-host-1.0.9-1.el8.noarch ovirt-imageio-common-2.3.0-1.el8.x86_64 ``` Any hint how to fix this is really appreciated. I'd like to get the engine appliance back, remove host 3 and re-initialize it since this is a production cluster (with hosts 1 and 2 replicating the gluster storage and host 3 acting as an arbiter). Thanks in advance, Martin

Re: Help installing oVirt on single machine, without cockpit

The reply button is making me write an email, so hopefully this reaches you all. > I think this thread (even if the title is not so clear about the discussions born inside) could be a good read regarding single host limitations in terms of updating the environment, after the initial deployment Cool, thanks for the advice! Based on the link, it seems like the hosted engine can't update on a "single machine" install. But if you install the engine directly to the host, the VM doesn't need to be running, so it might be able to. Thankfully I wasn't too far down playing with the hosted engine, or container setup yet. So with installing an engine directly to the node, I got it to install ovirt-engine, by enabling the appstream, baseos, extras, and powertools repo. Then I commented out all "includepkgs = ..." in both `/etc/yum.repos.d/ovirt-*.repo` files. I can also get through all of the `engine-setup` questions, but then it fails with starting the `ovirt-imageio` service at the very end. The logs in `/var/log/ovirt-imageio/daemon.log`: ```txt File "/usr/lib64/python3.6/site-packages/ovirt_imageio/_internal/ssl.py", line 16, in server_context purpose=ssl.Purpose.CLIENT_AUTH, cafile=cafile) File "/usr/lib64/python3.6/ssl.py", line 468, in create_default_context context.load_verify_locations(cafile, capath, cadata) FileNotFoundError: [Errno 2] No such file or directory ``` Which is the same error as this forum here: https://lists.ovirt.org/archives/list/users@ovirt.org/thread/DNB73ZMUB5DIMV… But all the info about solving it is " Found it; Default route was set to the NFS / SAN Network Gateway, not the Actual gateway.", and I'm not exactly sure what that means. I also tried the engine install/setup in a CentOS workstation VM, and it worked great, so I thought the node is missing a package? I installed `openssl-devel` without any luck. In both the VM and the node, I tried `route -n`, and both CentOS vm / node had similar/expected output. I tried to do as many default options as possible on both, so I'm surprised the gateway is different between them. Any idea how to get past this? I'm also open to switching to plain CentOS if that might be more stable, and installing to that. I just love how a lot of the node comes pre-packaged for you, and I'm not sure if you can install a "node hypervisor" straight to CentOS. That's also outside my comfort zone, so I'm open to advice either way. Thanks all for letting me get just this far!
