Install hosted engine using fcoe
by kyles＠aasteel.com 22 Feb '22

22 Feb '22

We're building a new cluster, but it utilizes fcoe for our storage. Is there a way to install the hosted engine using fcoe? I am unable to see our LUNs in the ovirt node currently as fcoe isn't enabled.

ansible ovirt_template: follow as replacement of nested_attributes
by Nathanaël Blanchet 21 Feb '22

21 Feb '22

Hello, I was familiar with the ansible fetch_nested/nested_attributes to get additionnal information from API. Recently it has been deprecated in order to be replaced by the "follow(s)" verb. I understand it will follow the links into the schema definition of the object like: <link href="/ovirt-engine/api/templates/e020281a-f5f0-4d98-91e3-4f3a9fc069b1/permissions" rel="permissions"/> <link href="/ovirt-engine/api/templates/e020281a-f5f0-4d98-91e3-4f3a9fc069b1/tags" rel="tags"/> <link href="/ovirt-engine/api/templates/e020281a-f5f0-4d98-91e3-4f3a9fc069b1/cdroms" rel="cdroms"/> <link href="/ovirt-engine/api/templates/e020281a-f5f0-4d98-91e3-4f3a9fc069b1/nics" rel="nics"/> <link href="/ovirt-engine/api/templates/e020281a-f5f0-4d98-91e3-4f3a9fc069b1/watchdogs" rel="watchdogs"/> <link href="/ovirt-engine/api/templates/e020281a-f5f0-4d98-91e3-4f3a9fc069b1/diskattachments" rel="diskattachments"/> <link href="/ovirt-engine/api/templates/e020281a-f5f0-4d98-91e3-4f3a9fc069b1/graphicsconsoles" rel="graphicsconsoles"/> but I can't get fetch nested (name of cluster) of : <cluster href="/ovirt-engine/api/clusters/bbeb38a4-79f0-11ec-86cb-00163e6d6a50" id="bbeb38a4-79f0-11ec-86cb-00163e6d6a50"/> I was used to do this query with: fetch_nested: yes nested_attribute: - name Is it possible to do the same with "follow(s)"? -- Nathanaël Blanchet Supervision réseau SIRE 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr

VMs losing network interfaces
by Jonathan Baecker 21 Feb '22

21 Feb '22

Hello everybody, I have here a strange behavior: We have a 3 node self hosted cluster with around 20 VMs running on it. Since longer I had the problem with one VM that after some days it lose the network interface. But because this VM was only for testing I was to lazy to dive more in, to figure out what is happen. Now I have a second VM, with the same problem and this VM is more important. Both VMs running debian 10 and use cifs mounts, so maybe that is related? Have some one of you seeing this behavior? And can give me a hint, how I can fix this? At the moment I can't provide a log file, because I didn't know the exact time, when this was happen. And I also don't know, if the problem comes from ovirt or from the operating system inside the VMs. Have a nice day! Jonathan

oVirt alternatives
by Thomas Hoberg 21 Feb '22

21 Feb '22

There is unfortunately no formal announcement on the fate of oVirt, but with RHGS and RHV having a known end-of-life, oVirt may well shut down in Q2. So it's time to hunt for an alternative for those of us to came to oVirt because they had already rejected vSAN or Nutanix. Let's post what we find here in this thread.

Re: ovirtmgmt VLAN and IP Change
by Abe E 20 Feb '22

20 Feb '22

Your method worked ! I additionally had to run the engine rename service script to change the hostname of the engine as well. My only issue now is after readding all the nodes with new hostnames my main host node 1 will not allow me to remove and re-add as a new hostname as there is a gluster volume on it. It will not let me remove to readd because theres a gluster on the volume, have you run into this?

How did you do this if the host had a gluster volume on it though? Mine does not let me remove due to that.

ovirtmgmt VLAN and IP Change
by Abe E 19 Feb '22

19 Feb '22

Hello All, So due to some issues with provisioning new networks in our lab, I have to use a different VLAN in for my ovirt cluster. Cluster -> 3 Hosts (Hyperconverged) What I want to do is essentially change the Ovirtmgmt interface to another vlan but also change the IP Schemes, I wont be needing to change the storage network vlans. I am just wondering how this is done safely. Can I through the engine, put the host 1 by 1 into maint mode and manually adjust the IPs and apply and reconfigure the switch port? What about the IP that the engine has set or would I change that manually through console once I change the ovirtmgmt vlan on all the nodes?

Random reboots
by Pablo Olivera 17 Feb '22

17 Feb '22

Hi community, We're dealing with an issue as we occasionally have random reboots on any of our hosts. We're using ovirt 4.4.3 in production with about 60 VM distributed over 5 hosts. We've a virtualized engine and a DRBD storage mounted by NFS. The infrastructure is interconnected by a Cisco 9000 switch. The last random reboot was yesterday February 14th at 03:03 PM (in the log it appears as: 15:03 due to our time configuration) of the host: 'nodo1'. At the moment of the reboot we detected in the log of the switch a link-down in the port where the host is connected. I attach log of the engine and host 'nodo1' in case you can help us to find the cause of these random reboots. Thanks in advance. Pablo.
