Can NFV (Network Functions Virtualization) work on oVirt?
by fukumoto.shinya＠fujitsu.com 04 Jan '21

04 Jan '21

Hello everyone, I've checked the documentation of oVirt, but cannot find if following function can work on oVirt or not. - NFV (Network Functions Virtualization) Does someone know NFV can work on oVirt? For your reference, Red Hat OpenStack Platform seems to support NFV as follows https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/12… Regards, Fukumoto

upload_disk.py - CLI Upload Disk

Hi All. I'm using version 4.4.4 (latest stable version - ovirt-node-ng-installer-4.4.4-2020122111.el8.iso) I tried using the upload_disk.py script, but I don't think I knew how to use it.

Windows 7 vm lost network connection under heavy network load
by Joey Ma 03 Jan '21

03 Jan '21

Hi folks, Happy holidays. I'm having an urgent problem :smile: . I've installed oVirt 4.4.2 on CentOS 8.2 and then created several Windows 7 vms for stress testing. I found that the heavy network load would lead to the e1000 net card NOT able to receive packets, it seemed totally blocked. In the meantime, packet sending was fine. Only re-enabling the net card can restore the network. Has anyone also had this problem? Looking forward to your insights. Much appreciated. Best regards, Joey

Cannot upgrade cluster to v4.5 (All hosts are CentOS 8.3.2011)
by Gilboa Davara 31 Dec '20

31 Dec '20

Hello all, I'm more-or-less finished building a new ovirt over glusterfs cluster with 3 fairly beefy servers. Nodes were fully upgraded to CentOS Linux release 8.3.2011 before they joined the cluster. Looking at the cluster view in the WebUI, I get an exclamation mark with the following message: "Upgrade cluster compatibility level". When I try to upgrade the cluster, 2 of the 3 hosts go into maintenance and reboot, but once the procedure is complete, the cluster version remains the same. Looking at the host vdsm logs, I see that once the engine refreshes their capabilities, all hosts return 4.2-4.4 and not 4.5. E.g. 'supportedENGINEs': ['4.2', '4.3', '4.4'], 'clusterLevels': ['4.2', '4.3', '4.4'] I assume I should be seeing 4.5 after the upgrade, no? AmI missing something? Thanks, - Gilboa

Best Practice? Affinity Rules Enforcement Manager or High Availability?
by souvaliotimaria＠mail.com 31 Dec '20

31 Dec '20

Hello everyone, Not sure if I should ask this here as it seems to be a pretty obvious question but here it is. What is the best solution for making your VMs able to automatically boot up on another working host when something goes wrong (gluster problem, non responsive host etc)? Would you enable the Affinity Manager and enforce some policies or would you set the VMs you want as Highly Available? Thank you very much for your time! Best regards, Maria Souvalioti

Then to migrate, you just need to power off the VM, Edit -> change cluster, network, etc and power it up. It will start on the hosts in the new cluster and then you just need to verify that the application is working properly. Best Regards, Strahil Nikolov

Breaking up a oVirt cluster on storage domain boundary.
by Matthew.Stier＠fujitsu.com 30 Dec '20

30 Dec '20

Is it possible to break up an oVirt cluster into multiple clusters? I have an Oracle Linux Virtualization Manager 4.3.6 cluster (think oVirt 4.3.6) that is hosting four different classes of VM's. I have acquired some additional hosts, and instead of adding them to my "default" cluster, I want to create three new clusters, and migrate each class of VM to its own cluster. Each class has its own network, and storage domains. Can I migrate storage domains, and thus all the VMs within that storage domain? Or will I need to build new cluster, with new storage domains, and migrate the VMs? Most of my VMs are built from templates. I assume that those cloned from templates will not be an issue. But some of my classes are thin provisioned, and I suspect I will have an issue with migrating those at the VM level, which is why I want to migrate them at the storage domain level.

Shrink iSCSI Domain
by Vinícius Ferrão 29 Dec '20

29 Dec '20

Hello, Is there any way to reduce the size of an iSCSI Storage Domain? I can’t seem to figure this myself. It’s probably unsupported, and the path would be create a new iSCSI Storage Domain with the reduced size and move the virtual disks to there and them delete the old one. But I would like to confirm if this is the only way to do this… In the past I had a requirement, so I’ve created the VM Domains with 10TB, now it’s just too much, and I need to use the space on the storage for other activities. Thanks all and happy new year.

Re: New to oVirt - HE and Metric Store Question
by Strahil Nikolov 28 Dec '20

28 Dec '20

I can't recall the exact issue that was reported in the mailing list, but I remember that the user had to power off the engine and the VMs... the Devs can clearly indicate the risks of running the HostedEngine with other VMs on the same storage domain. Based on Red Hat's RHV documentation the following warning is clearly indicating some of the reasons: Creating additional data storage domains in the same data center as the self-hosted engine storage domain is highly recommended. If you deploy the self-hosted engine in a data center with only one active data storage domain, and that storage domain is corrupted, you will not be able to add new storage domains or remove the corrupted storage domain; you will have to redeploy the self-hosted engine.

Cannot run yum, no internet connection on a oVirt node

Hello. I need help setting up the networking on the "self hosted engine" VM. I can't run yum in the self-hosted engine [1], there seems not to be any internet connection. I get the error "couldn't resolve host: mirrors.fedoraproject.org. Same thing when I do cURL google.com for example. Also I can't ssh to this VM from my physical machine either. I get "connection refused". I can ping the "self-hosted engine" VM though. Here is the output of ip addr on the "self hosted engine" VM: 2. enp1s0: .... state UP link/ether 52.54.... 3. virbr0: ... state DOWN inet 192.168.122.1 Here is the ip addr output on the host machine: 3. virbr0: ... state UP inet 192.168.122.1 Can someone please help me setup networking on the "self hosted engine" VM.

Moving VMs from 4.3.9 to 4.4.4
by Diggy Mc 28 Dec '20

28 Dec '20

What is the best way to move VMs from current 4.3.9 to a new 4.4.4. environment? The current environment is running oVirt 4.3.9 (started as 4.3.7). There is a single data domain using NFS on a single NAS. The future oVirt 4.4.4 environment will also have a single data domain using NFS on the same NAS as the current environment. What is the best way to move approximately 40 VMs from current 4.3.9 to a new 4.4.4. environment? Are there any caveats or considerations I need to take into account when moving the VMs? Your help, as always, is greatly appreciated.

New to oVirt - HE and Metric Store Question
by Nur Imam Febrianto 28 Dec '20

28 Dec '20

Hi, We’re migrating our 10 physical host with 50 small VM to oVirt from VMware and so happy with its performance. There are two question that we want to ask : 1. Right now we are using one SAN with 4 LUN (each mapped into 1 specific volume) and configure the storage domain for each LUn (1 LUN = 1 Storage Domain). Is this configuration are good ? One more, about Hosted Engine, when we setup the cluster, it provision one storage domain, but the storage domain is not exlusively used by Hosted Engine, we use it too for other VM. Are this OK or it have a side impact ? 2. We’re kind of interested using Metric Store (Need performance metric history over the time), is it possible to deploy the Metric Store using smaller resources ? Our hardware is so small, we cant afford to use that lot of resources for the Metric Store. Thanks before.

power management iLO5
by ozmen62＠hotmail.com 28 Dec '20

28 Dec '20

Hi, I've red mail list about IPMI fencing. But clould not find a solution. We have HP gen 10 servers. they have iLO5 and fencing does not work. In redhat there is a solution Issue No iLO5 fencing method available in RHV-manager Power Management via IPMILAN does not work on HPE Gen 10 systems Power Management via iLO4 does not work on HPE Gen 10 systems Resolution The IPMI interface has to be enabled in the security section of a iLO-5 on a HPE Gen 10 system in order to use the fence-agents iLO3, iLO4 or IPMILAN. A user with Login permissions and Operator level access for IPMI should be sufficient for fencing. Root Cause The default settings of iLO-5 on a HPE Gen 10 system have disabled IPMI access to the management controller. The fence agents for iLO-3 onward default to be using IPMI in order to communicate with the management controller. Therefore iLO3, iLO4 as well as IPMILAN fail to connect to a iLO-5 management controller. But, there is no IPMI option in power management. How can i enable power managemenet properly with iLO5 or IPMI? Thanks
