Snapshot and disk size allocation
by jorgevisentini＠gmail.com 28 Oct '21

28 Oct '21

Hello everyone. I would like to know how disk size and snapshot allocation works, because every time I create a new snapshot, it increases 1 GB in the VM's disk size, and when I remove the snap, that space is not returned to Domain Storage. I'm using the oVirt 4.3.10 How do I reprovision the VM disk? Thank you all.

Ooops! in last step of Hyperconverged deployment
by Harry O 24 Sep '21

24 Sep '21

Hi, In the second engine dep run in Hyperconverged deployment I get red "Ooops!" in cockpit. I think it fails on some networking setup. The first oVirt Node says "Hosted Engine is up!" but the other nodes is not added to HostedEngine yet. There is no network connectivity to the Engine outside node1, I can ssh to engine from node1 on the right IP-address. Please tell what logs I should pull.

by Vrgotic, Marko 14 Sep '21

Dear oVirt, We are currently running oVirt 4.3 and upgrade/migration to 4.4 won’t be possible for few more months. I am looking into guidelines, how to, for setting up Grafana using DataWarehouse as data source. Did anyone already did this, and would be willing to share the steps?

Hi, If I create a template with a snapshot of the vm that uses the mbs disk, the template cannot be used to create a new vm. Is this normal or a bug?

Error when trying to change master storage domain
by Matthew Benstead 11 Sep '21

11 Sep '21

Hello, I'm trying to decommission the old master storage domain in ovirt, and replace it with a new one. All of the VMs have been migrated off of the old master, and everything has been running on the new storage domain for a couple months. But when I try to put the old domain into maintenance mode I get an error. Old Master: vm-storage-ssd New Domain: vm-storage-ssd2 The error is: Failed to Reconstruct Master Domain for Data Center EDC2 As well as: Sync Error on Master Domain between Host daccs01 and oVirt Engine. Domain: vm-storage-ssd is marked as Master in oVirt Engine database but not on the Storage side. Please consult with Support on how to fix this issue. 2021-07-28 11:41:34,870-07 WARN [org.ovirt.engine.core.vdsbroker.irsbroker.IrsProxy] (EE-ManagedThreadFactory-engine-Thread-23) [] Master domain version is not in sync between DB and VDSM.

Template for Ubuntu 18.04 Server Issues
by jeremy_tourville＠hotmail.com 02 Sep '21

02 Sep '21

I have built a system as a template on oVirt. Specifically, Ubuntu 18.04 server. I am noticing an issue when creating new vms from that template. I used the check box for "seal template" when creating the template. When I create a new Ubuntu VM I am getting duplicate IP addresses for all the machines created from the template. It seems like the checkbox doesn't fully function as intended. I would need to do further manual steps to clear up this issue. Has anyone else noticed this behavior? Is this expected or have I missed something? Thanks for your input!

Terrible Disk Performance on Windows 10 VM
by regloff＠gmail.com 05 Aug '21

05 Aug '21

I recently installed a Windows 10 VM under oVirt 4.4.5.11-1.el8 Also installed the drivers using "virtio-win-1.9.16.iso" (Then re-installed them after updates just in case it helped) I found a similar complaint with VMWare (https://communities.vmware.com/t5/VMware-Workstation-Pro/vmware-workstation…) So I looked into that and made a registry change for the AHCI controller, as well as setting the 'viodiskcache' to write-back (Seen in another thread on here) - those two changes seemed to help.. marginally. But not much at all. When I do just about anything, disk usage spikes to 100% and stays there for quite a while. Write speeds rarely break 100kb/sec. Not even sure what to look for next. My Linux VMs don't seem to have this issue and the host it's running on is barely working at all. CPU and memory stay close to unused. oVirt didn't show a lot, but in task manager in the Windows VM - you can see disk queue just pegged completely. I've given the VM 6GB of RAM, so that's not it. I even turned off paging in the Windows VM as well, to no avail. This is an example of disk usage, just opening 'Groove Music' for the first time. https://i.postimg.cc/FRLq28Mw/Disk-Activity.png Any ideas? :)

Restored engine backup: The provided authorization grant for the auth code has expired.
by Nicolás 05 Aug '21

05 Aug '21

Hi, I'm restoring a full ovirt engine backup, having used the --scope=all option, for oVirt 4.3. I restored the backup on a fresh CentOS7 machine. The process went well, but when trying to log into the restored authentication system I get the following message which won't allow me to log in: The provided authorization grant for the auth code has expired. What does that mean and how can it be fixed? Thanks. Nicolás
