migrate hosted-engine vm to another cluster?
by Douglas Duckworth 17 Jan '19

17 Jan '19

Hello I am trying to migrate my hosted-engine VM to another cluster in the same data center. Hosts in both clusters have the same logical networks and storage. Yet migrating the VM isn't an option. To get the hosted-engine VM on the other cluster I started the VM on host in that other cluster using "hosted-engine --vm-start." However HostedEngine still associated with old cluster as shown attached. So I cannot live migrate the VM. Does anyone know how to resolve? With other VMs one can shut them down then using the "Edit" option. Though that will not work for HostedEngine.

Disk full
by suporte＠logicworks.pt 16 Jan '19

Hi, I have a all in one intallation with 2 glusters volumes. The disk of one VM filled up the brick, which is a partition. That partition has 0% free disk space. I moved the disk of that VM to the other gluster volume, the VM is working with the disk on the other gluster volume. When I move the disk, it didn't delete it from the brick, the engine keeps complaining that there is no more disk space on that volume. What can I do? Is there a way to prevent this in the future? Many thanks José -- Jose Ferradeira http://www.logicworks.pt

Ovirt Engine UI bug- cannot attache networks to hosts
by Leo David 05 Jan '19

05 Jan '19

Hi Everyone, Using self hosted-engine 4.2.7.5-1.el7 running on ovirt-node 4.2.7, i am trying to attache hosts to a newlly created network for gluster/migration traffic. Oncei click on Networks->gluster-Hosts- Unattached, i get the following error: Uncaught exception occurred. Please try reloading the page. Details: (TypeError) : M9(...) is null Please have your administrator check the UI logs So to make the cluster installation possible, i had to use ovirt 4.2.2 and manually install ovirt-engine-appliance-4.2-20180626.1.el7 on the nodes before deploying self-hosted engine ( version that has other problems, like not being able to get dasboards in cloudforms/manageiq - ovirt-engine-dwh is missing ). Is it possible to: 1. upgrade actual hosted-engine version to the latest that has this module properly installed ? 2. fix the latest ( upgraded ) version so i can attach hosts to networks ? Thank you very much ! Leo -- Best regards, Leo David

Unable to increase memory or CPU on hosted Engine version 4.2.5.2
by Florian Schmid 04 Jan '19

04 Jan '19

Hi, I'm using version 4.2.5.2 and every article I found, I read that with oVirt 4.2, it should be possible to update CPU and memory for hosted Engine in UI. Now, when I'm trying to do this, even being on global maintenance, I always get the same error: Error while executing action: HostedEngine: There was an attempt to change Hosted Engine VM values that are locked. My problem is, that I need to increase the memory, because we had now several times in the last 2 or 3 months an out of memory kill of the java process. What is the best way to increase memory here? Should I do it over the config file? But how is then the OVF updated? BR Florian

GlusterFS Storage - Size limited at 2 GB
by v.levet＠isiline.net 03 Jan '19

Hello everyone, I've installed oVirt on 8 nodes of a MacroServer (SuperMicro Microcloud): 7 Nodes with oVirt Node installed and 1 Node with Centos 7 and oVirt installed. The last one works like hypervisor and node. I would use all the storage of all nodes like a Gluster storage, so I've created a new DataCenter, with a Cluster with all nodes inside. Then I've created the volume Gluster (by GUI): Replicated Duplicated version and 4 replicas on all 8 nodes. Than "Optimize for oVirt Storage". For last I've created Domain storage based on volume created before. All works fine but the total storage that is available from Domain is 1.9 GB. I've tried already to force it using these commands: gluster volume GlusterVol limit-usage / 3200GB gluster volume quota GlusterVol limit-usage /data 3200GB At first it seems work but finally when I was installing a VM, I get Full Storage. It seems that it could use only the storage of the node where is instantiated the volume. I would see all the storage distributed and I wish I could use the storage from all nodes. Someone could help me?

Vm console direct connection
by Leo David 03 Jan '19

Hello everyone, Could someone be so kind to tell me if there's any chance that virt-viewer or any other client can be used to directly connect to vms running on oVirt without the need for the user to access the portal first ? Thank you very much ! Cheers, Leo

Acquire an XML dump of a VM oVirt?
by Jacob Green 02 Jan '19

How does one get an XML dump of a VM from ovirt? I have seen ovirt do it in the engine.log, but not sure how to force it to generate one when I need it. Thank you. -- Jacob Green Systems Admin American Alloy Steel 713-300-5690

Running different minor versions in different clusters?
by Florian Schmid 02 Jan '19

02 Jan '19

Hi, I want to ask, if this is a supported Environment, when I have for example the latest 4.2 version running on engine and all hosts in a cluster have an earlier release of 4.2 running? Example: - ovirt engine: 4.2.7 - hosts in cluster A: 4.2.5 - hosts in cluster B: 4.2.7 The engine VM would run in cluster A with the older version. I ask, because we have a very huge ovirt setup, split into different clusters. In one cluster, I would like to have always the latest version and in the others, the upgrade will be done in bigger time-intervals. LG Florian Schmid
