[ovirt 4.2]The snapshot is deleted after restoring the snapshot
by liuweijie＠sunyainfo.com 03 Sep '20

03 Sep '20

Dear All: I used ovirt api (POST /ovirt-engine/api/vms/{vm:id}/snapshots) to create several snapshots. When I call the snapshot recovery api (POST /ovirt-engine/api/vms/{vm:id }/snapshots/{snapshot:id}/restore) to restoe the first snapshot, I found that the next few snapshots were deleted, and it was normal when I restored the last snapshot. Why does the snapshot with the earlier recovery time delete the subsequent snapshot? The vm's os is centos. Hope get help from you soon, Thank you. Yours sincerely， Evelyn

Ovirt Host Crashed
by Darin Schmidt 02 Sep '20

02 Sep '20

I am running this as an all in one system for a test bed at home. The system crashed which lead me to have to reinstall the OS (CentOS 8) and I imported the data stores but I cannot find any way to import the VM's that were in the DATA store. I havent had a chance to backup/export the VMs. I havent been able to find anything in the documentation on how to import these VMs. Any suggestions or links to what Im looking for? I had to create a new DATA store as the option for importing a local data store wasnt an option, I assume its because the host was down. THen I imported the old data store.

Mellanox OFED with oVirt
by Vinícius Ferrão 02 Sep '20

02 Sep '20

Hello, Anyone had success using Mellanox OFED with oVirt? Already learned some things: 1. I can’t use oVirt Node. 2. Mellanox OFED cannot be installed with mlnx-ofed-all since it breaks dnf. We need to rely on the upstream RDMA implementation. 3. The way to go is running: dnf install mlnx-ofed-dpdk-upstream-libs But after the installation I ended up with broken dnf: [root@c4140 ~]# dnf update Updating Subscription Management repositories. Last metadata expiration check: 0:03:54 ago on Tue 01 Sep 2020 11:52:41 PM -03.

How can Gluster be a HCI default, when it's hardly ever working?
by thomas＠hoberg.net 02 Sep '20

02 Sep '20

I've just tried to verify what you said here. As a base line I started with the 1nHCI Gluster setup. From four VMs, two legacy, two Q35 on the single node Gluster, one survived the import, one failed silently with an empty disk, two failed somewhere in the middle of qemu-img trying to write the image to the Gluster storage. For each of those two, this always happened at the same block number, a unique one per machine, not in random places, as if qemu-img reading and writing the very same image could not agree. That's two types of error and a 75% failure rate I created another domain, basically using an NFS automount export from one of the HCI nodes (a 4.3 node serving as 4.4 storage) and imported the very same VMs (source all 4.3) transported via a re-attached export domain to 4.4. Three of the for imports worked fine, no error with qemu-img writing to NFS. All VMs had full disk images and launched, which verified that there is nothing wrong with the exports at least. But there was still one, that failed with the same qemu-img error. I then tried to move the disks from NFS to Gluster, which internally is also done via qemu-img, and I had those fail every time. Gluster or HCI seems a bit of a Russian roulette for migrations, and I am wondering how much it is better for normal operations. I'm still going to try moving via a backup domain (on NFS) and moving between that and Gluster, to see if it makes any difference. I really haven't done a lot of stress testing yet with oVirt, but this experience doesn't build confidence.

HP blade G7, with be2net.
by Remulo 01 Sep '20

01 Sep '20

Hello I have some blades with 10GE interface that have / need the Emulex be2net driver, however it is no longer available on Redhat8 / Centos8. Is there any way to install ovirt to work on these machines? Here are some links to problems with Redhat. Emulex NIC using be2net driver https://access.redhat.com/solutions/1229853 https://access.redhat.com/solutions/514353 I did a lot of research and couldn't get a functional driver for ovirt. Thank you. -- Atenciosamente, Rêmulo Ferreira.

How can you avoid breaking 4.3.11 legacy VMs imported in 4.4.1 during a migration?
by thomas＠hoberg.net 01 Sep '20

01 Sep '20

Testing the 4.3 to 4.4 migration... what I describe here is facts is mostly observations and conjecture, could be wrong, just makes writing easier... While 4.3 seems to maintain a default emulated machine type (pc-i440fx-rhel7.6.0 by default), it doesn't actually allow setting it in the cluster settings: Could be built-in, could be inherited from the default template... Most of my VMs were created with the default on 4.3. oVirt 4.4 presets that to pc-q35-rhel8.1.0 and that has implications: 1. Any VM imported from an export on a 4.3 farm, will get upgraded to Q35, which unfortunately breaks things, e.g. network adapters getting renamed as the first issue I stumbled on some Debian machines 2. If you try to compensate by lowering the cluster default from Q35 to pc-i44fx the hosted-engine will fail, because it was either built or came as Q35 and can no longer find critical devices: It evidently doesn't take/use the VM configuration data it had at the last shutdown, but seems to re-generate it according to some obscure logic, which fails here. I've tried creating a bit of backward compatibility by creating another template based on pc-i440fx, but at the time of the import, I cannot switch the template. If I try to downgrade the cluster, the hosted-engine will fail to start and I can't change the template of the hosted-engine to something Q35. Currently this leaves me in a position where I can't separate the move of VMs from 4.3 to 4.4 and the upgrade of the virtual hardware, which is a different mess for every OS in the mix of VMs. Recommendations, tips anyone? P.S. A hypervisor reconstructing the virtual hardware from anywhere but storage at every launch, is difficult to trust IMHO.

Upgrade Doc typo.
by carl langlois 01 Sep '20

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]

Re: Promiscuous Mode

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

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

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?

Missing model_FLAGS on specific host

I know this model_ flags are an oVirt thing, since they aren’t default on the CPUs. The host machine is a Dell C4140 compute node, the firmware is fully updated, so I’ve done the basic to figure out what’s happening. Thanks,

ovirt 4.4 self-hosted deployment questions
by Michael Thomas 28 Aug '20

28 Aug '20

I have not been able to find answers to a couple of questions in the self-hosted engine documentation[1]. * When installing a new Enterprise Linux host for ovirt, what are the network requirements? Specifically, am I supposed to set up the ovirtmgmt bridge myself on new hosts, or am I supposed to let that be handled by the engine when I add the new host to the engine? * In the 'New Host' dialog on the engine management page, does the Hostname/IP that I enter have to be the host's name on the ovirtmgmt LAN? If so, then it seems to me that I need to configure the ovirtmgmt bridge myself on new hosts. * Does the engine need to be able to route outside of the cluster (eg to the WAN), or is it allowed to restrict the engine's routing to the local cluster? * In the 'New Host' dialog on the engine management page, what is the meaning of 'Choose hosted engine deployment action'? From the way it is phrased, it sounds like this will create a second engine in my cluster, which doesn't make sense. Or does this mean that the new host will be able to run the Engine VM in a HA manner? In my current test deployment I have 3 subnets in my cluster. Network WAN is the WAN. Network CLUSTER is for communication between cluster compute nodes, storage servers, and management servers. Network OVIRT is for ovirt management and VM migration between hosts. My first self-hosted engine host is connected to networks CLUSTER and OVIRT. The engine VM is only connected to network OVIRT through a bridge on the host, but has a gateway that lets it route traffic to network CLUSTER (but not network WAN). Is this an appropriate network setup for ovirt, or should there be no distinction between the CLUSTER and OVIRT networks? --Mike [1]https://www.ovirt.org/documentation/installing_ovirt_as_a_self-hosted_eng…

TroubleshootingoVirt Node deploy FQDN not reachable
by David White 27 Aug '20

27 Aug '20

In a recent thread, Roberto mentioned seeing the error message "FQDN Not Reachable" when trying to deploy oVirt Node 4.4.1, but was able to get past that error when using ovirt-node-ng-installer-4.4.2-2020080612.el8.iso. I experienced the same problems on oVirt Node install 4.4.1, so I tried the latest release of 4.4.2. When that failed, I went back and installed from the exact same image as Roberto said worked on the 4.4.2 branch: ovirt-node-ng-installer-4.4.2-2020080612.el8.iso Unfortunately, that's still not working for me - so that tells me I'm probably doing something wrong. Given the following facts: [root@dev1-centos ~]# hostname dev1-centos.office.barredowlweb.com [root@dev1-centos ~]# host dev1-centos.office.barredowlweb.com dev1-centos.office.barredowlweb.com has address 192.168.2.96 I am trying to install oVirt using the Hyperconverged Gluster Wizard for a Single Node. In the "Host1" box, I enter the full hostname: dev1-centos.office.barredowlweb.com And that's when I get the FQDN error message. Am I missing something here? Sent with ProtonMail Secure Email.

Is the Hosted Engine setup finished + Can't connect vdsm storage
by Bielej SRE 27 Aug '20

27 Aug '20

Hi, We have 6 node oVirt setup with Compatibility version 4.3 running on CentOS 7.6.1810 Recently We have found out some very interesting log entries on a few of our nodes. /var/log/ovirt-hosted-engine-ha/broker.log: MainThread::INFO::2020-08-27 12:51:50,279::storage_backends::345::ovirt_hosted_engine_ha.lib.storage_backends::(connect) Connecting the storage MainThread::INFO::2020-08-27 12:51:50,280::storage_server::349::ovirt_hosted_engine_ha.lib.storage_server.StorageServer::(connect_storage_server) Connecting storage server MainThread::warning::2020-08-27 12:51:50,284::storage_broker::97::ovirt_hosted_engine_ha.broker.storage_broker.StorageBroker::(__init__) Can't connect vdsm storage: 'NoneType' object has no attribute 'startswith' /var/log/messages Aug 27 12:52:11 ildeco25 vdsm[6909]: ERROR failed to retrieve Hosted Engine HA score '[Errno 2] No such file or directory'Is the Hosted Engine setup finished? We have inherited that setup from the previous team but I'm fairly certain the the Hosted Engine setup is finished. Also, this line is not present on all hosts. Should We worry about ovirt-ha-broker service not running on some hosts? host24 Active: inactive (dead) host25 Active: failed (Result: start-limit) since Thu 2020-08-27 12:56:13 CEST; 2s ago host26 Active: active (running) since Sun 2020-08-23 22:55:01 CEST; 3 days ago host27 Active: inactive (dead) host28 Active: failed (Result: start-limit) since Thu 2020-08-27 12:56:18 CEST; 4s ago host29 Active: inactive (dead) Currently the hosted engine VM is running on host26. I'd be very grateful for any help. Kind regards, Michal Bielejewski
