Hello team, I have the rhv plateform installed with the monitoring tool grafana with default dashboard (executive, inventory, servicelevel and trend). I would like to know how i can create a dashboard which will monitor the hosts status more precisely the status (down, up or in maintenance and list them).

OVF_Store In Every Storage Doamin - Can We Remove?

by Matthew J Black

Hi All, The Subject pretty much sums up the question I want to ask: There are two OVF_Store Disks created in all eight Storage Domains we have, making 16 total. This is cluttering up several of our views in the oVirt Admin Webpages. Is there anything stopping us from deleting some/all of these? Cheers Dulux-Oz

Error try setting up oVirt 4.5 with AD using ovirt-engine-extension-aaa-ldap-setup

by kalilac＠gmail.com

Hello all. I just did a fresh install of oVirt 4.5 running on top of CentOS 9 Stream. Everything was fine but when I try to setting up to use our AD, using the ovirt-engine-extension-aaa-ldap-setup command, always return me this error: [WARNING] Cannot resolve Global Catalog SRV record for XXXX.XXX.XX. Please check you have entered correct Active Directory forest name and check that forest is resolvable by your system DNS servers [ ERROR ] Failed to execute stage 'Environment customization': Active Directory forest is not resolvable, please make sure you've entered correct forest name. If for some reason you can't use forest and you need some special configuration instead, please refer to examples directory provided by ovirt-engine-extension-aaa-ldap package. What is strange is that if we try to resolve our AD name responds fine. oVirt version: 4.5.4-1.e|9 CentOS version: Stream 9 Ovirt-engine-extension-aaa-ldap-setup: 1.4.6-1.el9 Anyone passed for this? Best regards

Thin provisioning max size

by Jean-Louis Dupond

Hi, This weekend we've got an issue with a disk that did not get extend anymore because of the following reason: > 2022-12-17 12:12:27,852+0100 INFO (libvirt/events) [virt.vm] (vmId='a2926e08-d19b-4e3a-98fa-cc1ee241a037') abnormal vm stop device ua-6ccc3ee1-02e5-4fad-b1b7-9f2d6c187416 error enospc (vm:5185) > 2022-12-17 12:12:27,852+0100 INFO (libvirt/events) [virt.vm] (vmId='a2926e08-d19b-4e3a-98fa-cc1ee241a037') CPU stopped: onIOError (vm:6066) > 2022-12-17 12:12:27,852+0100 INFO (libvirt/events) [virt.vm] (vmId='a2926e08-d19b-4e3a-98fa-cc1ee241a037') drive 'sda' needs extension (storage:963) > 2022-12-17 12:12:27,854+0100 INFO (libvirt/events) [virt.vm] (vmId='a2926e08-d19b-4e3a-98fa-cc1ee241a037') CPU stopped: onSuspend (vm:6066) > 2022-12-17 12:12:27,931+0100 INFO (periodic/3) [virt.vm] (vmId='a2926e08-d19b-4e3a-98fa-cc1ee241a037') Drive sda extended to maximum size, disabling monitoring (thinp:357) Now I looked into the VDSM code, and noticed that some years ago there was a commit https://github.com/oVirt/vdsm/commit/93e955af9e4989711403e81835bb469b2e9c... Where the estimate of 1.1x the disk size was used as max size. But is this 1.1x still valid? As for example since some years there are dirty bitmaps etc which all take space in the qcow2 image. As far as I see there is no way to really calculate the exact max size (as it might depend on external factors), but it might be useful to extend the 1.1x to 1.2x for example? Or maybe the limit is not needed anymore at all? Thanks Jean-Louis

attaching a diskto a vm with the incremental statement

by Nathanaël Blanchet

Hello, I am used to create new vm with ovirt_vm module. Now, I want that the disk of each new created vm to be with the incremental statement. I tried so: disks: - id: "{{result.disk.id}}" bootable: True interface: virtio_scsi backup: incremental but it seems that the backup item is not implemented. How to attach a disk with the incremental statement?

Hosted Engine 4.5 Deployment Issues

by nathan.english＠bt.com

Hi There, Apologies in advanced, I'm sure this has been asked before, but I struggle to find anything in the documentation. I'm currently in the process of deploying my first oVirt instance, and having a issue when the Hosted Engine is trying to Install the Hosted Engine Package. Error from the logs attached. My Environment is behind a proxy, which blocks access to any domain containing the word mirror, so I understand why the error would be thrown. Is there any way to update the repos so I can point them to alternative sources? I have a working local mirror in my environment which does contain all the packages required for oVirt. Kind Regards, Nathan

oVirt Biz Continuity Plan recovery Q/A

by siebots＠protonmail.com

Hello all, I am looking into implemented a BCP plan with oVirt, which intends to recover VMs from a secondary SAN LUN (containing VM snapshots from a production oVirt cluster site which is considered to have crashed/burned) and presented to the recovery site oVirt cluster. Since the production cluster is expected to have crashed/burned unexpectedly, leaving the VMs snapshots on the recovery SAN LUN (which is at a different site) intact. However since there can be no Export Domain / Import Domain scenario, I need to know what exact steps I need to perform to re-incorporate/re-hydrate the VMs from the recovery LUN presented to the recover oVirt cluster / KVM hosts. I think that normally an Import Domain offers a "VM Import" tab/option, while regular or non-import Storage Domains don't have the "VM Import" option. I've been trying to track down what exactly is needed in the way of specific steps within the oVirt manager and KVM hosts, besides presenting the recovery SAN LUN to it. Many thanks.

Unable to start VM with SRIOV IB interface

by oliveira＠uc.pt

Hi everyone, On a new oVirt 4.4.10.7-1.el8 deployment I am unable to star a VM with a SRIOV IB interface. I always get the message: Error while executing action: login003: Cannot run VM. There is no host that satisfies current scheduling constraints. See below for details: The host nvirt002.lca.uc.pt did not satisfy internal filter HostDevice because the host does not provide requested host devices. The host nvirt000.lca.uc.pt did not satisfy internal filter HostDevice because some of the required host devices are unavailable. The host nvirt003.lca.uc.pt did not satisfy internal filter HostDevice because the host does not provide requested host devices. The host nvirt005.lca.uc.pt did not satisfy internal filter HostDevice because the host does not provide requested host devices. The host nvirt004.lca.uc.pt did not satisfy internal filter HostDevice because the host does not provide requested host devices. The host nvirt001.lca.uc.pt did not satisfy internal filter HostDevice because the host does not provide requested host devices. Given that I am trying to run it on login000 I guess the relevant error is that the host device is unavailable. I cannot find any other errors or messages that seem relevant to this on any other logs. How do I even start debugging this? I have another deployment with 4.3 where it just works. Best Regards and thank you, Miguel Oliveira
