Few hosts shows unable to launch vms due memory is not available to schedule vm. However vm has enough memory when check free command. If any one come across such issue, please let me know how we can fix it in oracle olvm

PsqlException at Engine
by Christoph Koehler 08 Aug '25

08 Aug '25

Dear all, Since the last host update to the latest master snapshot, we have encountered a situation where hosts with the following CPU can no longer be activated: Xeon Gold 5418Y. The error comes from a database function of the engine: "PSQLEXCEPTION: ERROR: value too long for type character varying(4000) Where: SQL statement "UPDATE vds_dynamic SET cpuflags = vcpu_flags WHERE vdsid = vvds_id" PL/pgSQL function updatecpuflags(uuid, character varying) line 3 at SQL statement" Since the update, the length of the CPU flags exceeds the datatype varchar(4000) as declared in the DB. Currently, we have no solution, and the nodes remain 'unassigned'. Does anyone know of a workaround or when this presumably known error will be fixed? Thank you and best regards, Christoph

Re: [External] : Custom OMVF for VM

Hi Domien, Possible it is, but you will need to test this deployment. The firmware json files are stored under /usr/share/qemu/firmware on each KVM host, and the fd files are stored under /usr/share/edk2/ovmf/ on the KVM hosts, too. As far as I understand, and you need to confirm it, the Chipset/Firmware Type option in the web UI is retrieved from the PostgreSQL database requiring you to add additional entries to it so the web portal will display the corresponding options to deploy this appliance. The good point, by going this path you will be able to create a great blog article describing how to create a custom entry in oVirt to deploy Sonicwall in it.

Unable to start engine, vm status "Paused"

Hello everyone, the engine switched to paused state after attempting to place a host into maintenance, specifically when i selected the option to stop the gluster service. Glusterfs is 3 bricks [root@ovirt10 glusterfs]# gluster v heal engine info Brick 10.64.7.10:/gluster_bricks/engine/engine Status: Connected Number of entries: 0 Brick 10.64.7.11:/gluster_bricks/engine/engine Status: Connected Number of entries: 0 Brick 10.64.7.12:/gluster_bricks/engine/engine Status: Connected Number of entries: 0 --== Host ovirt11 (id: 3) status ==-- Host ID : 3 Host timestamp : 34188104 Score : 3400 Engine status : {"vm": "up", "health": "bad", "detail": "Paused", "reason": "bad vm status"} Cluster is in global maintenance The ovirt node i attempted to place in maintenance had no vms running (ovirt21) attempting to restart the engine when gluster is not running on ovirt21 results in the following error: MainThread::WARNING::2025-07-01 13:05:25,988::storage_broker::100::ovirt_hosted_engine_ha.broker.storage_broker.StorageBroker::(__init__) Can't connect vdsm storage: path to storage domain 4d31ba9e-5167-4af8-bc2a-361cce9b8278 not found in /rhev/data-center/mnt/glusterSD If i restart glusterd, and ovirt-agent and ovirt-broker on the host i put into maintenance (ovirt21), then attempt to restart the engine vm, it starts up but then is paused shortly after when glusterd service is automatically stopped on ovirt node 21. It seems the engine is stuck trying to put that host into maintenance, as soon as the engine vm starts it's paused when glusterd is stopped on ovirt21. Is there a way to safely unmount the engine gluster volume from the empty host without affecting the rest of the cluster? and/or, is there a way to stop the engine from putting that host into maintenance? Thanks! Mario M
