mask or disabled lldpad service
by Klaas Demter 28 Aug '18

28 Aug '18

Hi, I have a QLogic Corp. QLogic 2x1GE+2x10GE QL41162HMRJ CNA network card. This network card comes with it's own lldp implementation inside their management firmware. Running two lldp agents seems to create several issues (http://lists.us.dell.com/pipermail/linux-poweredge/2018-July/051860.html) The QLogic engineers said I need to disable lldpad in the operating system. This leads me here, what is lldp actually used for within ovirt? If it is actually needed how could I deal with a card that does not support lldpad but rather has it's own implementation? Greetings Klaas

VDO + HCI = failed reboots
by Donny Davis 28 Aug '18

28 Aug '18

I just spun up the latest and greatest ovirt has to offer, and I am building out an HCI cluster. The deployment went wonderfully. I had dns setup for everything, and it just worked. Great job team! I just wanted to add in something i noticed after rebooting the nodes. The gluster service, and volumes would not come back up after rebooting. I found that there needs to be an entry in the fstab for the gluster logical volumes to tell them to start the vdo service. So without this, the node will fail to boot if you are using vdo. inode64,noatime,nodiratime,discard,x-systemd.requires=vdo.service the defaults are this inode64,noatime,nodiratime Hopefully it helps someone else :) Cheers

Migrating to HCI
by Vincent Royer 27 Aug '18

27 Aug '18

I have 2 hosts using NFS storage I want to migrate to HCI and add a third host. Have added the 10Gbe cards and drives to the 3 target hosts and setup a separate physical network for storage. Can I: - deploy a single-node HCI to host 3 - export the VMs to an NFS export domain - Import the VMs to the HCI node - wipe the first 2 hosts and re-deploy them to the HCI DC Is there a guide for this? or should I just export the VMs, blow away all the nodes, and deploy as a 3-node HCI using the wizards? I'm hoping to minimize downtime of the VMs to under one day. *Vince*

One Windows VM is not responding
by Jonathan Baecker 27 Aug '18

27 Aug '18

Hello Everybody! We have here 13 VMs running under ovirt 4.2.4. Two of them are Windows Server 2016. On one runs a AD, DNS and one application. On the second one runs an SQL Server and also an application. This second one have the problem, that periodical it goes in a state where I get in ovirt the message: *not responding * Beside this the VM is running normal. I can connect it over Remote Desktop. But I can not connect it with ovirt/noVNC, the button is gray out. In a weekly cycle it runs a backup script, maybe this brings some problems, but I really don't know how to debug this. It can be that the VM runs for 3 weeks normal, and then it goes in this state, so I can not really say when this is happen. Also the fact that the other Windows Server VM runs normal, wonders me. Do you have experienced this problem, or do you know how I found out the issue? Best Regards! Jonathan

Re: External ceph storage
by Luca 'remix_tj' Lorenzetto 27 Aug '18

27 Aug '18

No, The only way you have is to configure cinder to manage ceph pool or in alternative you have to deploy an iscsi gateway, no other ways are available at the moment. So you can't use rbd directly.

Unknown CPU model Broadwell-IBRS-SSBD
by me＠brendanh.com 24 Aug '18

24 Aug '18

Hi, I've just installed hosted-engine. It proceeds to near the end of the Ansible script, then pauses at: "TASK [Check engine VM health]" then eventually errors: "Engine VM is not running, please check vdsm logs. The VDSM logs have error: "libvirtError: internal error: Unknown CPU model Broadwell-IBRS-SSBD" Also, in the oVirt Node webui, the HostedEngine VM is created, but not started. If I press Run, the following error is shown: VM START action failed error: Failed to start domain HostedEngine error: internal error: Unknown CPU model Broadwell-IBRS-SSBD I notice a Trello card was created to add similar Skylake & EPYC CPUs, but not Broadwell: https://trello.com/c/5nGTgQ9P/89-new-ibrs-and-ssbd-cpu-types# Does the Broadwell-IBRS-SSBD CPU need to be added to this supported types list? Many thanks.
