Hello! I have read the documentation on the web site, but still it is not clear for me : is it possible to install ovirt engine as well as guests on virtual machines, not on the real hardware?

Ovirt 4.2.1 Storage with Fibre Channel Protocol
by Sérgio Marques 05 Mar '18

05 Mar '18

Hello, I'm new in Ovirt, loving it, but i'm having some doubts when it comes to add FCP Storage. I have two clusters, one called Production and the other Development, each cluster with two nodes and i want to configure Data Domain. My doubts are: 1 - Every nodes must have connection to de FCP? If only de SPM have it, if it falls, who can connect to the storage? 2 - I have only one LUN in EVA HSV300 for me and i want to add three Storage Domains (Data, ISO e Export). Is it possible? How? This is because when i add data storage domain and choose the only LUN available it warn me that all data is going to be lost "This operation might be unrecoverable and destructive" 3 - Any advice about best practices about implementation? Thanks -- Cumprimentos, Sérgio Marques

Problem Storage Iscsi
by João Floriano - Magnet 05 Mar '18

05 Mar '18

Hello everyone! I am facing the following problem with ovirt 4.2.1, out of nowhere all virtual machines are paused and only return operals if log in via ssh on the host and execute a "virsh destroy domain", it is necessary to reactivate disk and network after this process. In the events I get the following message: VM X has been paused due to storage I / O problem. Currently I have iscsi storage configured on a server with target and based on some test I did not identify problems of communication of the hosts to the storage can you help me? --

VM paused rather than migrate to another hosts
by Terry hey 05 Mar '18

05 Mar '18

Dear all, I am testing iSCSI bonding failover test on oVirt, but i observed that VM were paused and did not migrate to another host. Please see the details as follows. I have two hypervisors. Since they are running iLO 5 and oVirt 4.2 cannot support iLO 5, thus i cannot setup power management. For the cluster setting, I set "Migrate Virtual Machines" under the Migration Policy. For each hypervisor, I bonded two iSCSI interface as bond 1. I created one Virtual machine and enable high availability on it. Also, I created one Virtual machine and did not enable high availability on it. When i shutdown one of the iSCSI interface, nothing happened. But when i shutdown both iSCSI interface, VM in that hosts were paused and did not migrate to another hosts. Is this behavior normal or i miss something? Thank you all of you. Regards, Terry Hung

VMs stuck in migrating state
by nicolas＠devels.es 05 Mar '18

Hi, We're running 4.1.9 and during the weekend we had a storage issue that seemed to leave some hosts in an strange state. One of the hosts has almost all VMs migrating (although it seems to not actually being migrating them) and the migration state cannot be cancelled. When clicking on one of those machines and selecting 'Cancel migration', in the ovirt-engine log I see: 2018-02-26 08:52:07,588Z INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.CancelMigrateVDSCommand] (org.ovirt.thread.pool-6-thread-36) [887dfbf9-dece-4f7b-90a8-dac02b849b7f] HostName = host2.domain.com 2018-02-26 08:52:07,588Z ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.CancelMigrateVDSCommand] (org.ovirt.thread.pool-6-thread-36) [887dfbf9-dece-4f7b-90a8-dac02b849b7f] Command 'CancelMigrateVDSCommand(HostName = host2.domain.com, CancelMigrationVDSParameters:{runAsync='true', hostId='e63b9146-10c4-47ad-bd6c-f053a8c5b4eb', vmId='26d37e43-32e2-4e55-9c1e-1438518d5021'})' execution failed: VDSGenericException: VDSErrorException: Failed to CancelMigrateVDS, error = Migration process cancelled, code = 82 On the vdsm side I see: 2018-02-26 08:56:19,396+0000 INFO (jsonrpc/0) [vdsm.api] START migrateCancel() from=::ffff:10.X.X.X,54654, flow_id=874d36d7-63f5-4b71-8a4d-6d9f3ec65858 (api:46) 2018-02-26 08:56:19,398+0000 INFO (jsonrpc/0) [vdsm.api] FINISH migrateCancel return={'status': {'message': 'Migration process cancelled', 'code': 82}, 'progress': 0} from=::ffff:10.X.X.X,54654, flow_id=874d36d7-63f5-4b71-8a4d-6d9f3ec65858 (api:52) So no error on the vdsm side log. I already tried restarting ovirt-engine but it didn't work. Could someone shed some light on how to cancel the migration status for these machines? All of them seem to be running on the same host. Thanks.

oVirt 4.2.x and ManageIQ : Adding 'cfme' credentials
by Nicolas Ecarnot 04 Mar '18

04 Mar '18

Hello, As for my 4 previous oVirt DCs, I'm trying to add them to ManageIQ providers. I tried to follow this guide : https://access.redhat.com/documentation/en-us/red_hat_cloudforms/4.6/html-s… But when trying to run psql, the shell tells me the command is not found. I made a very simple setup : when running engine-setup, I answered the default question about DWH, so the DB is local. When viewing (with pgAdmin) the roles of this new PostgreSQL DB, I see there is no 'cfme' user. Do I have to re-run the setup and answer different things to ensure other packages and setup are made? I saw https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.1/ht… telling me to re-run. But I see that : rpm -qa|grep -i dwh ovirt-engine-dwh-4.2.1.2-1.el7.centos.noarch ovirt-engine-dwh-setup-4.2.1.2-1.el7.centos.noarch so I thought it was already enough... ? -- Nicolas ECARNOT

Change management network
by Chris Boot 03 Mar '18

03 Mar '18

Hi all, I have an oVirt cluster on which I need to change which VLAN is the management network. The new management network is an existing VM network. I've configured IP addresses for all the hosts on this network, and I've even moved the HostedEngine VM onto this network. So far so good. What I cannot seem to be able to do is actually change the "management network" toggle in the cluster to this network: the oVirt Engine complains saying: "Error while executing action: Cannot edit Network. Changing management network in a non-empty cluster is not allowed." How can I get around this? I clearly cannot empty the cluster, as the cluster contains all my existing VMs, hosts and HostedEngine. Best regards, Chris -- Chris Boot bootc(a)boo.tc

oVirt network tries to reassign my bridge address to herself
by Anastasiya Ruzhanskaya 03 Mar '18

03 Mar '18

Hello! I have two VM - they are machines on which I test installation. I don't want any clusters, advanced features. My goal is two connect engine and host, shut down everything, then turn on and have right configuration. However my VMs are connected via bridge, and oVirt also use another bridge to connect them. Because of this on startup I have a problem, that two bridges are trying to assign the same address. What can be done in this case?
