Hi, Not sure if this is relevant but in the ovirt doc in the 4.2 to 4.3 upgrade the repo rpm is specified with 4,4 rpm . Thanks Carl [image: image.png]

Not sure it will actually do that, but if you create a new network profile, you can select a 'port mirroring' option: It is my understanding that is what you need. You may also want to deselect the filtering rules in the same place.

can't mount an export domain with 4K block size (VDO) as PosixFS (xfs)
by thomas＠hoberg.net 31 Aug '20

31 Aug '20

After this (https://devconfcz2020a.sched.com/event/YOtG/ovirt-4k-teaching-an-old-dog-ne…) I sure do not expect this (log below): Actually I am trying to evaluate just how portable oVirt storage is and this case I had prepared a USB3 HDD with VDO, which I could literally move between farms to transport VMs. Logical disks are typically large for simplicity within the VMs, QCOW2 and VDO assumed to compensate for this 'lack of planning' while the allocated storage easily fits the HDD. Once I got beyond the initial issues, I came across this somewhat unexpected issue: VDO storage uses 4k blocks all around, but evidently when you mount an export domain (or I guess any domain) as POSIX, 512byte blocks are assumed somewhere and 4k blocks rejected. I'd say that is a bug in VDSM, right? Or is there anything in the mount options to fix this? 020-08-31 18:44:40,424+0200 INFO (periodic/0) [vdsm.api] START repoStats(domains=()) from=internal, task_id=7a293dec-85b3-4b82-92b7-4e7d03b40343

Promiscuous Mode
by Anton Louw 31 Aug '20

31 Aug '20

Hi All, I would like to deploy a VM that will monitor a specific network. I know in VMware you can set the port group to allow Promiscuous Mode. Is there something similar I can do in oVirt? Thanks Anton Louw Cloud Engineer: Storage and Virtualization ______________________________________ D: 087 805 1572 | M: N/A A: Rutherford Estate, 1 Scott Street, Waverley, Johannesburg anton.louw(a)voxtelecom.co.za www.vox.co.za

How to extend timeout? Thanks in advance, Gianluca

Hosted Engine stuck in Firmware
by Vinícius Ferrão 30 Aug '20

30 Aug '20

Hello, I’ve an strange issue with oVirt 4.4.1 The hosted engine is stuck in the UEFI firmware trying to “never” boot. I think this happened when I changed the default VM mode for the cluster inside the datacenter. There’s a way to fix this without redeploying the engine?

deprecating export domain?
by Charles Kozler 30 Aug '20

30 Aug '20

Hello, I recently read on this list from a redhat member that export domain is either being deprecated or looking at being deprecated To that end, can you share details? Can you share any notes/postings/bz's that document this? I would imagine something like this would be discussed in larger audience This seems like a somewhat significant change to make and I am curious where this is scheduled? Currently, a lot of my backups rely explicitly on an export domain for online snapshots, so I'd like to plan accordingly Thanks!

shutdown virtual machine did not display in the list when using virsh list --all and virsh list --state-shutoff
by Kyre 30 Aug '20

30 Aug '20

Hello, I am using ovirt 4.3.8. I want to use the virsh command to boot the shutdown virtual machine, but when using virsh list --all and virsh list --state-shutoff, the shutdown virtual machine did not display in the list. What is the cause of this, and how can I display the shutdown virtual machine. virsh # list --all Please enter your authentication name: root Please enter your password:  Id    Name                           State ----------------------------------------------------  4     win10E2                  running virsh # list --state-shutoff  Id    Name                           State ----------------------------------------------------

Ovirt Node 4.4.2 Engine Deployment - Notification Settings
by David White 30 Aug '20

30 Aug '20

I finally got oVirt node installed with gluster on a single node. So that's great progress! Once that step was complete... I noticed that the Engine Deployment wizard asks for SMTP settings for where to send notifications. I was kind of surprised that it doesn't allow one to enter any credentials. It looks like this requires an unauthenticated local relay. I don't like that. :) See attached screenshot. Has there been any talk about adding this into the wizard deployment?
