Hi all, Hope you all are doing well. Checkout this new oVirt blog: oVirt Monitoring Alerts via Grafana <https://blogs.ovirt.org/2021/08/ovirt-monitoring-alerts-via-grafana/>. The blog explains how to configure alerts in Grafana for your oVirt environment and provides an example alerts dashboard that you can import, use and edit to your needs. When using alerts significant or critical data changes can be immediately recognized, so don't miss this opportunity to learn how to configure and use this important tool. Feedback, comments and suggestions are more than welcome! -- Aviv Litman BI Associate Software Engineer Red Hat <https://www.redhat.com/> alitman(a)redhat.com <https://www.redhat.com/>

by ssarang520＠gmail.com 13 Sep '21

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 12 Sep '21

12 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.

We are using oVirt for several years. And we start with Xeon v2 CPUs. At this moment of time we got all v3 aтв we will chnage them to v4 in a month. So i would like to change Cluster default CPU to Haswell, But got error with custom cpu on HostedEngine. HostedEngine config is locked. Is there a solution to chnage HostedEngine cpu type? P.S. some problem with Cluster compability version (4.5 4.6)

Correct way to install VDSM hooks
by Shantur Rathore 06 Sep '21

06 Sep '21

Hi all, I am trying to install vdsm hooks (scratchpad) specifically. I can see that there are rpms available in https://resources.ovirt.org/pub/ovirt-4.4/rpm/el8/noarch/ but when I try to install using yum it says it cannot find it. Do I have to manually select the hook rpm and install it or am I missing something? Kind regards, Shantur

NFS storage was locked for 45 minutes after I attempted a clone operation
by David White 03 Sep '21

03 Sep '21

I have an HCI cluster running on Gluster storage. I exposed an NFS share into oVirt as a storage domain so that I could clone all of my VMs (I'm preparing to move physically to a new datacenter). I got 3-4 VMs cloned perfectly fine yesterday. But then this evening, I tried to clone a big VM, and it caused the disk to lock up. The VM went totally unresponsive, and I didn't see a way to cancel the clone. Nagios NRPE (on the client VM) was reporting server load over 65+, but I was never able to establish an SSH connection. Eventually, I tried restarting the ovirt-engine, per https://access.redhat.com/solutions/396753. When that didn't work, I powered down the VM completely. But the disks were still locked. So I then tried to put the storage domain into maintenance mode, but that wound up putting the entire domain into a "locked" state. Finally, eventually, the disks unlocked, and I was able to power the VM back online. From start to finish, my VM was down for about 45 minutes, including the time when NRPE was still sending data to Nagios. What logs should I look at, and how can I troubleshoot what went wrong here, and hopefully avoid this from happening again? Sent with ProtonMail Secure Email.

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!
