gluster and virtualization
by eevans＠digitaldatatechs.com 02 Feb '22

02 Feb '22

My setup is 3 ovirt nodes that run gluster independently of the engine server, even thought the engine still controls it. So 4 nodes, one engine and 3 clustered nodes. This has been and running with no issues except this: But now my arbiter node will not load the gluster drive when virtualization is enable in the BIOS. I've been scratching my head on this and need some direction. I am attaching the error. https://1drv.ms/u/s!AvgvEzKKSZHbhMRQmUHDvv_Xv7dkhw?e=QGdfYR Keep in mind, this error does not occur is VT is turned off..it boots normally. Thanks in advance.

Host needs to be reinstalled after configuring power management
by Andrew DeMaria 02 Feb '22

02 Feb '22

Hi, I am running ovirt 4.3 and have found the following action item immediately after configuring power management for a host: Host needs to be reinstalled as important configuration changes were applied on it. The thing is - I've just freshly installed this host and it seems strange that I need to reinstall it. Is there a better way to install a host and configure power management without having to reinstall it after? Thanks, Andrew

migration infinite loop
by Renaud RAKOTOMALALA 02 Feb '22

02 Feb '22

Hi, I switch an host in "PreparingForMaintenance" state to prepare an upgrade. In this stage the host migrating all VM but failed on one due to a network's congestion. Because the host try to migrate this VM and the constant failure of the migration, we enter in an infinite loop. How can I stop this loop ? I’m not able to cancel the mainteance mode with the WebUI. Any idea ? Thanks -- Renaud

Cinderlib RBD ceph template issues
by Sketch 01 Feb '22

01 Feb '22

This is on oVirt 4.4.8, engine on CS8, hosts on C8, cluster and DC are both set to 4.6. With a newly configured cinderlib/ceph RBD setup. I can create new VM images, and copy existing VM images, but I can't copy existing template images to RBD. When I do, I try, I get this error in cinderlib.log (see below), which sounds like the disk already exists there, but it definitely does not. This leaves me unable to create new VMs on RBD, only migrate existing VM disks. 2021-09-01 04:31:05,881 - cinder.volume.driver - INFO - Driver hasn't implemented _init_vendor_properties() 2021-09-01 04:31:05,882 -

no snaphot but engines complains there is one when trying to remove disk
by Nathanaël Blanchet 01 Feb '22

01 Feb '22

Hi all, A colleague launched this morning a snapshot creation, there was no error message but he wasn't able to start the vm anymore, with this issue : VM PSI-SYB-DEV is down with error. Exit message: Unable to get volume size for domain a5be6cae-f0c8-452f-b7cd-70d0e5eed710 volume 109fac1e-c2e3-4ba6-9867-5d1c94d3a447.. I tried many things but nothing works: it is impossible to remove this disk, or copy it, or clone the vm : Cannot detach Virtual Disk. The disk is already configured in a snapshot. In order to detach it, remove the disk's snapshots. There is no snaphost listed into webui or api (so not snapshot id), while disk_snapshots exists into the associated storage domain. So I tried to remove disks snapshot direvctly with API followind the DELETE method |DELETE /api/storagedomains/{storage_id}/disksnapshots/{image_id}| [Cannot remove Disk Snapshot. VM\'s Snapshot does not exist.] In conclusion: vm_disks can't be removed because of the non existent associated vm's snapshot id. I tried to remove vm_snapshots disks references directly into the postgres DB but I didn't find the correct table. What can I do now? Your precious help is welcome. -- Nathanaël Blanchet Supervision réseau SIRE 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr

oVirt 4.4.10 Async update #2
by Sandro Bonazzola 30 Jan '22

30 Jan '22

On January 26th 2022 the oVirt project released an async update to the following packages: - ovirt-engine 4.4.10.6 Fixing the following bugs: - [BZ 2044277 <https://bugzilla.redhat.com/show_bug.cgi?id=2044277>] - Replace ovirt-engine-extension-logger-log4j with internal ovirt-engine implementation Package ovirt-engine-extension-logger-log4j has been obsoleted and replaced by internal ovirt-engine implementation in oVirt Engine 4.4.10.6. During upgrade from previous oVirt versions to oVirt 4.4.10 ovirt-engine-extension-logger-log4j package is uninstalled if it was previously installed. If you used ovirt-engine-extension-logger-log4j in previous oVirt versions, you will need to manually remove existing ovirt-engine-extension-logger-log4j configuration files and configure the new feature of sending log records to remote syslog service according to the Administration Guide. Also after successful upgrade to oVirt 4.4.10 you can manually uninstall log4j12 package without breaking oVirt setup: $ dnf remove log4j12 - [BZ 2044257 <https://bugzilla.redhat.com/show_bug.cgi?id=2044257>] - Bump snmp4j library version to remove dependency on log4j oVirt Engine 4.4.10.6 is requiring snmp4j >= 3.6.4, which no longer depends on log4j library -- Sandro Bonazzola MANAGER, SOFTWARE ENGINEERING, EMEA R&D RHV Red Hat EMEA <https://www.redhat.com/> sbonazzo(a)redhat.com <https://www.redhat.com/> *Red Hat respects your work life balance. Therefore there is no need to answer this email out of your office hours.*
