Move HostedEngine to new data domain.
by Diggy Mc 05 Jan '21

05 Jan '21

Running oVirt 4.3.9 and would like to move the HostedEngine VM in its entirety (disks, templates, etc) from its current data domain to a new one. How can this be done? Once the engine VM has been moved, I can simply detach the data domain with all existing VMs from my 4.3 environment and then attach it to my new 4.4 environment, correct?

upload_disk.py - CLI Upload Disk
by Jorge Visentini 03 Jan '21

03 Jan '21

Hi All. I'm using version 4.4.4 (latest stable version - ovirt-node-ng-installer-4.4.4-2020122111.el8.iso) I tried using the upload_disk.py script, but I don't think I knew how to use it. When I try to use it, these errors occur: *python3 /usr/share/doc/python3-ovirt-engine-sdk4/examples/upload_disk.py disk01-SO.qcow2 --disk-format qcow2 --sd-name ISOsusage: upload_disk.py [-h] -c CONFIG [--debug] [--logfile LOGFILE] [--disk-format {raw,qcow2}] [--disk-sparse] [--enable-backup] --sd-name SD_NAME [--use-proxy] [--max-workers MAX_WORKERS] [--buffer-size BUFFER_SIZE] filenameupload_disk.py: error: the following arguments are required: -c/--config* Using the upload_disk.py help: *python3 upload_disk.py --help-c CONFIG, --config CONFIG Use engine connection details from [CONFIG] section in ~/.config/ovirt.conf.* This CONFIG, is the API access configuration for authentication? Because analyzing the script I did not find this information. Does this new version work differently or am I doing something wrong? In the sdk_4.3 version of upload_disk.py I had to change the script to add the access information, but it worked. *[root@engineteste01 ~]# python3 upload_disk.py disk01-SO.qcow2Checking image...Disk format: qcow2Disk content type: dataConnecting...Creating disk...Creating transfer session...Uploading image...Uploaded 20.42%Uploaded 45.07%Uploaded 68.89%Uploaded 94.45%Uploaded 2.99g in 42.17 seconds (72.61m/s)Finalizing transfer session...Upload completed successfully[root@engineteste01 ~]#* Thank you all!! -- Att, Jorge Visentini +55 55 98432-9868

Windows 7 vm lost network connection under heavy network load
by Joey Ma 03 Jan '21

03 Jan '21

Hi folks, Happy holidays. I'm having an urgent problem :smile: . I've installed oVirt 4.4.2 on CentOS 8.2 and then created several Windows 7 vms for stress testing. I found that the heavy network load would lead to the e1000 net card NOT able to receive packets, it seemed totally blocked. In the meantime, packet sending was fine. Only re-enabling the net card can restore the network. Has anyone also had this problem? Looking forward to your insights. Much appreciated. Best regards, Joey

Cannot upgrade cluster to v4.5 (All hosts are CentOS 8.3.2011)
by Gilboa Davara 31 Dec '20

31 Dec '20

Hello all, I'm more-or-less finished building a new ovirt over glusterfs cluster with 3 fairly beefy servers. Nodes were fully upgraded to CentOS Linux release 8.3.2011 before they joined the cluster. Looking at the cluster view in the WebUI, I get an exclamation mark with the following message: "Upgrade cluster compatibility level". When I try to upgrade the cluster, 2 of the 3 hosts go into maintenance and reboot, but once the procedure is complete, the cluster version remains the same. Looking at the host vdsm logs, I see that once the engine refreshes their capabilities, all hosts return 4.2-4.4 and not 4.5. E.g. 'supportedENGINEs': ['4.2', '4.3', '4.4'], 'clusterLevels': ['4.2', '4.3', '4.4'] I assume I should be seeing 4.5 after the upgrade, no? AmI missing something? Thanks, - Gilboa
