Changing disk QoS causes segfault with IO-Threads enabled (oVirt 4.3.0.4-1.el7)
by jloh＠squiz.net 23 Apr '24

23 Apr '24

We recently upgraded to 4.3.0 and have found that when changing disk QoS settings on VMs whilst IO-Threads is enabled causes them to segfault and the VM to reboot. We've been able to replicate this across several VMs. VMs with IO-Threads disabled/turned off do not segfault when changing the QoS. Mar 1 11:49:06 srvXX kernel: IO iothread1[30468]: segfault at fffffffffffffff8 ip 0000557649f2bd24 sp 00007f80de832f60 error 5 in qemu-kvm[5576498dd000+a03000] Mar 1 11:49:06 srvXX abrt-hook-ccpp: invalid number 'iothread1' Mar 1 11:49:11 srvXX libvirtd: 2019-03-01 00:49:11.116+0000: 13365: error : qemuMonitorIORead:609 : Unable to read from monitor: Connection reset by peer Happy to supply some more logs to someone if they'll help but just wondering whether anyone else has experienced this or knows of a current fix other than turning io-threads off. Cheers.

virt-v2v cannot authenticate with oVirt engine API with OAuth2
by malcolm.strydom＠pacxa.com 23 Mar '24

23 Mar '24

I've been reading through archives but not able to find what i need. Essentially what I'm trying to do is migrate a larger number of VMs from our OVM environment to a new OLVM setup. In an effort to reduce lots of replication and copying of the disk image (export, convert, copy over, import etc.) I found this article which shows a pretty slick way to do it in one shot https://blogs.oracle.com/scoter/post/how-to-migrate-oracle-vm-to-oracle-lin… The main command behind it all is the virt-v2v that makes it possible. It looks something like this: virt-v2v -i libvirtxml vm-test1.xml -o rhv-upload -oc https://<OLVM-server>/ovirt-engine/api -os <my storage> -op /tmp/ovirt-admin-password -of raw -oo rhv-cluster=Default -oo rhv-cafile=/root/ca.pem The problem I'm having is I cannot authenticate with my new OLVM server at the ovirt-engine/api URL. Since user/password is depricated and you must use OAuth 2.0 with a token I'm stuck. I have OLVM 4.5.4-1.0.27.el8 and from what I've read in oVirt 4.5 (not sure what version it started) they use keycloak oAuth 2.0 and the older ovirt-aaa-jdbc-tool is now deprecated. In doing some testing I found I can use curl and authenticate against the ovirt-engine/api and get a token like this: OVIRT_ENGINE_URL="https://<myolvm1>/ovirt-engine" USERNAME="admin@ovirt@internalsso" PASSWORD="<mypassword>" CLUSTER_NAME="Default" TOKEN=$(curl -k -X POST -H "Accept: application/json" -H "Content-Type: application/x-www-form-urlencoded" -d "grant_type=password &username=$USERNAME&password=$PASSWORD&scope=ovirt-app-api" $OVIRT_ENGINE_URL/sso/oauth/token | jq -r '.access_token') I was then able to query the API to validate my token works curl -k -H "Accept: application/json" -H "Authorization: Bearer $TOKEN" "$OVIRT_ENGINE_URL/api/clusters?search=name=$CLUSTER_NAME" The problem is virt-v2v does not support posting any form information or the token to authenticate. Best I can tell the -oc option is strictly the URL and if you want a username in there it's in the form of https://<name>@<server>. So even if I wrote a script and used curl to authenticate and get a token I still can't find a way to make virt-v2v use it. So I'm stuck how do I get virt-v2v working? Is there a way to re-enable the deprecated user/pass method of accessing the ovirt-engine/api ? or as a last resort a way to get virt-v2v supporting the token? Thanks for any insight Malcolm

Ovirt 4.5 HA over NFS fails when a single host goes down
by youssef.khristo＠elsewedyintel.com 13 Mar '24

13 Mar '24

Greetings, we have recently installed ovirt as a hosted-engine with high availability on six nodes over NFS storage (no Gluster), with power management through an on-board IPMI device, and the setup was successful. All the nodes (from Supermicro) are identical in every aspect, so no hardware differences exist and no modifications to the servers' hardware were performed. The hosted-engine was deployed on a second host, where two of the six hosts only were required to host the HE VM. The network interface on each node is bonded between two physical fiber optics NICs in LACP mode with a VLAN on top, serving as the sole networking interface for the server/node, no separate VM or storage networks were needed, as the host OS, hosted-engine vm, and storage are required to be on the same network and VLAN. We started by testing the high-availability of the hosted-engine VM (as it was deployed on two of the six nodes) by rebooting or powering off one of the hosts, and the VM would migrate successfully to the second HE node. The main goal of our experiments is to test the robustness of the setup, as it is required for the cluster to remain functional even when up to two hosts are brought down (whether due to a network or power issue), however, when rebooting or powering off one of the hosts, the HE VM goes down and takes the entire cluster with it, where we can't even access the web portal. Once the host is rebooted, the HE VM and the cluster becomes functional again. Sometimes the HE VM stays down for a set amount of time (5 to 6 minutes) and then goes back up, and sometimes it goes down until the problematic host is back up. This behavior happens to other VMs as well not the the HE. We suspected an issue with the NFS storage, however, during ovirt operation it is being mounted properly over /rhev/data-center/mnt/<nfs:directory>, while the expected behavior is for the cluster to stay operational and any other VMs to be migrated to other hosts. During one of the tests, we tried to mount the NFS storage on a different directory and there was no problem, we were even able to perform commands such as ls without any issues, as well as writing a text file at the directory's root, and be able to modify it normally. We suspected a couple of things the first being that the HE is unable to fence the problematic host (the one we took down), however, power management is setup properly. The other thing we suspected is the cluster hosts (after taking down one of them) are unable to acquire storage lease, which is weird since the host in question is down and non-operational, hence no locks should be in place. The reason behind this suspicion is the following two errors that we receive frequently when one host or more goes down from the engine\ovirt-engine\engine.log file: 1- "EVENT_ID: VM_DOWN_ERROR(119), VM HostedEngine is down with error. Exit message: resource busy: Failed to acquire lock: Lease is held by another host." 2- "[<id>] Command 'GetVmLeaseInfoVDSCommand( VmLeaseVDSParameters:{expectedEngineErrors='[NoSuchVmLeaseOnDomain]', storagePoolId='<pool-id>', ignoreFailoverLimit='false', leaseId='<lease-id>', storageDomainId='<domain-id>'})' execution failed: IRSGenericException: IRSErrorException: No such lease: 'lease=<lease-id>'" This is a third warning from the /var/log/vdsm/vdsm.log file 1- "WARN (check/loop) [storage.check] Checker '/rhev/data-center/mnt/<nfs-domain:/directory>/<id>/dom_md/metadata' is blocked for 310.00 seconds (check:265)" All the tests are done without setting nodes into maintenance mode as we are simulating an emergency situation. No HE configuration were modified via the config-engine command, the default values are used. Is this a normal behavior? Are we missing something? Do we need to tweak a certain configuration using the config-engine command to get a better behavior (e.g., shorter down period)? Best regards

Advice on upgrading oVirt 4.2 CentOS 7.x cluster to oVirt 4.5 Rocky Linux 8.9
by ovirt＠the-dawg.net 01 Mar '24

01 Mar '24

I have multiple aging clusters that I now need to upgrade both the host OS and the oVirt release. I have seen the notes about upgrading 4.2 to 4.3 and then being able to upgrade to 4.5, but what's not so clear is how to upgrade the host nodes' OS versions. After thinking about it, I wonder if this method is sane. Any advice or guidance is greatly appreciated. 1) spin up a new cluster running oVirt 4.5.x on the latest Rocky Linux release. 2) shutdown VMs on the original cluster 3) detach the domain storage 4) snapshot the domain storage (for rollback) 5) import the domain on the new cluster. 6) reload the OS on the original cluster to the new OS release (no local storage) 7) add those hosts to the new cluster

Snapshots and mess with Storage
by thorsten.bolten＠googlemail.com 29 Feb '24

Hi, I experienced a weird Failure. I hope I explain it understandable and not too hard to read We had issues with our backups, that they can't finalize Here is a Thread someone having the same issue. https://forums.veeam.com/ovirt-kvm-f62/veeam-rhv-12-1-command-removeimageti… so I made some investigations and recognized, it seems to be an Issue with Snapshot 1. I created a Snapshot https://paste.fo/c0b8e77a3400 what works 2. Then I tried to deleted the snapshot, what didn't work https://paste.fo/013e5632e0d6 So I logged in to a node and checked several things First strange thing was, I can see pvs vgs etc, I am used, that ovirt hides them in the System (on one of those nodes it's still the case) but anyways [root@ovnb05 ~]# pvs WARNING: Couldn't find device with uuid uHJs0a-T7R3-2H8E-15W9-cGqW-ZN1e-xsdCsb.

virtio-scsi. SSD vs HDD
by duparchy＠esrf.fr 28 Feb '24

28 Feb '24

HI, Is there a way to set a disk as being SSD (which really is). Or, better, set an entire Storage Domain being SSD ? This would prevent the schedule optimization to be automatically ON in Windows. and maybe enable other underlying optimization (TRIM ?)
