iSCSI storage maintenance
by Martijn Grendelman 26 May '16

26 May '16

Hi, I have a simple oVirt setup, with one storage server and a couple of hypervisors, running some 50 VMs. The storage server uses ZFS zvols, exported over iSCSI with SCST. Now I want to do some maintenance on the storage, specificly I want to update SCST to a new version. I expect that the normal procedure for this would be: - shutdown all VMs - put storage domain into maintenance - perform maintenance - get everything back online Now I know I can also take the following ugly shortcut: - stop SCST daemon - see all VMs go to Paused - perform maintenance - restart SCST - resume all VMs or wait for them to resume themselves The win being of course, that nothing has to be restarted/rebooted. Extremely small scale testing (one running VM on a 20 GB test domain) indicates, that this works like a charm. The VM resumes without a problem and doesn't log anything storage related. My question is: what are the risks involved in the shortcut scenario? I understand that there are IOPS that never reach the disk, so they have to be queued somewhere (inside Qemu I presume). What happens if this happens with 50 VMs at once? Best regards, Martijn.

SELinux and oVirt
by Cam Mac 26 May '16

26 May '16

Hi, In the oVirt guide, it says that "SELinux is being used by default on oVirt Node", but then goes on to say that if you have problems you should set it to permissive mode. I have had a few things fail due to being blocked by SELinux on a node I later enabled SELinux on, as it was off at install time. The other node which has had SELinux on from the start and so far has not had any oVirt operations blocked. I am guessing that the oVirt install process creates the necessary rules to allow vdsm to run under SELinux. So if you want to set SELinux to enforcing after installation, is there a script to do this, or is it better to just reinstall the node or engine, rather than trying to work out the individual exceptions? Thanks, Cam

Struggling to get the network work

This is a multi-part message in MIME format. --------------010106010903030101040605 Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 7bit Hi, I have a peculiar problem with oVirt 3.6. Any VM connected to ovrtmgmt is working absolutely fine, bu the VMs (Windows Guests) in different VLANs say 10, 32, 34, 40, 48 & 69 are not able to even ping their respective gateways. In other words, network packets are not coming out of the VMs at all. 1. Our infrastructure consists of Lenovo Flex Chassis with 3 Lenovo x240 Compute nodes. All nodes are up and running and VMs are also created and guest OS installed. 2. Chassis switch has a trunk port that carries all VLAN traffic. 3. I have created logical networks and added VLAN tags (10, 32, 24, 40, 48 & 69). 4. I have attached the vNIC to each host and assigned static IP in respective VLANs. For example in VLAN 32, the vNIC is assigned with 172.20.101.70, subnet: 255.255.255.192, Gateway: 172.20.101.65 5. VMs are mapped with respective vNIC and assigned IPs in respective VLAN. For Example, VM in VLAN 32 has 172.20.101.79 as IP, 255.255.255.192 as subnet and 172.20.101.65 as gateway. Now, VM is able to ping vNIC in VLAN 32, but neither VM is able to ping the gateway nor hosts are able to ping vNIC or the VM. We even attempted with replacing a trunk port with access port, but same issue continues. What could have gone wrong? Any thing missing on oVirt configuration? A quick help is highly appreciated. -- -- Thanks & Regards, Anantha Raghava --------------010106010903030101040605 Content-Type: text/html; charset=utf-8 Content-Transfer-Encoding: 7bit <html> <head> <meta http-equiv="content-type" content="text/html; charset=utf-8"> </head> <body text="#000000" bgcolor="#FFFFFF"> Hi,<br> <br> I have a peculiar problem with oVirt 3.6.

Could not connect to the optimizer service
by Kapetanakis Giannis 26 May '16

Hi, I've just setup optimizer service following http://www.ovirt.org/develop/release-management/features/sla/optaplanner/ and https://github.com/oVirt/ovirt-optimizer I can access optimizer's interface and get the the solution result from both http and https. I can access it from both my pc and from ovirt-engine host with a browser at url ovirt-optimizer/result/Cluster_ID However in ovirt-engine interface I see Status: Could not connect to the optimizer service [status code: 0] Also I see no connection attempt from ovirt-engine to optimizer (with logging on optimizer's firewall). Engine is loading the conf: 2016-05-25 13:54:40,395 INFO [org.ovirt.engine.ui.frontend.server.gwt.plugin.PluginDataManager] (default task-20) [] Reading UI plugin configuration '/etc/ovirt-engine/ui-plugins/ovirt-optimizer-config.json' /etc/ovirt-engine/ui-plugins/ovirt-optimizer-config.json: "config": { "baseurl": "https://optimizer.example.com/ovirt-optimizer/result/" tried also "config": { "baseurl": "http://optimizer.example.com/ovirt-optimizer/result/" incase there was a problem with optimizer's certificate. Any ideas? How can I debug why the engine is not doing any attempt to get optimizer's result? best regards, Giannis

On 3.6.6, tried doing a live VM storage migration... didn't work
by Christopher Cox 25 May '16

25 May '16

In our old 3.4 ovirt, I know I've migrated storage on live VMs and everything seemed to work. However on 3.6.6, I tried this and I saw the warning about moving storage on a live VM (it wasn't doing much of anything) and I went ahead and migrated the storage from one storage domain to another. But when it was through, even though the VM was still alive, when I tried to write to a virtual disk that was part of the move, it paused the VM saying there wasn't enough storage. I could unpause the VM, but in a few seconds, with things writing to the virtual disk, again it was paused with the same out of space message. Vdsm logs showed the enospc return code... so it made sense, it's just that the VM shows plenty of storage there. Once I rebooted the VM, everything went back to normal. So is moving storage for a live VM not supported? I guess we got lucky in our 3.4 system (?)

Cinder Snapshot Issues
by Kevin Hrpcek 25 May '16

25 May '16

Hello, I'm running into a problem with live snapshots not working when using cinder/ceph disks. There are different failures for including and not including memory, but in each case cinder/ceph creates a new snapshot that can be seen in cinder and ceph. When doing a memory/disk snapshot the VM ends up in a paused state and I need to kill -9 the qemu process to be able to boot the vm again. The engine seems to be losing connection with the vdsm process on the VM host after freezing the guest's filesystems. The guest never receives the thaw command and it fails in the logs. I am pasting in some log snippets. 2016-04-12 19:24:58,851 INFO [org.ovirt.engine.core.bll.CreateAllSnapshotsFromVmCommand] (org.ovirt.thread.pool-8-thread-27) [5c4493e] Ending command 'org.ovirt.engine.core.bll.CreateAllSnapshotsFromVmCommand' successfully. 2016-04-12 19:27:56,873 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (DefaultQuartzScheduler_Worker-27) [4d97ca06] Correlation ID: null, Call Stack: null, Custom Event ID: -1, Message: VDSM OVCL1A command failed: Message timeout which can be caused by communication issues 2016-04-12 19:27:56,873 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.SnapshotVDSCommand] (DefaultQuartzScheduler_Worker-27) [4d97ca06] Command 'org.ovirt.engine.core.vdsbroker.vdsbroker.SnapshotVDSCommand' return value 'StatusOnlyReturnForXmlRpc [status=StatusForXmlRpc [code=5022, message=Message timeout which can be caused by communication issues]]' 2016-04-12 19:27:56,874 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.SnapshotVDSCommand] (DefaultQuartzScheduler_Worker-27) [4d97ca06] HostName = OVCL1A 2016-04-12 19:27:56,874 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.SnapshotVDSCommand] (DefaultQuartzScheduler_Worker-27) [4d97ca06] Command 'SnapshotVDSCommand(HostName = OVCL1A, SnapshotVDSCommandParameters:{runAsync='true', hostId='9bdfaedc-34a8-4a08-ad8a-c117835a6094', vmId='040609f6-cfe0-4763-8b32-08ffad158c93'})' execution failed: VDSGenericException: VDSNetworkException: Message timeout which can be caused by communication issues 2016-04-12 19:27:56,875 WARN [org.ovirt.engine.core.vdsbroker.VdsManager] (org.ovirt.thread.pool-8-thread-16) [4d97ca06] Host 'OVCL1A' is not responding.

add user permissions to a template

25 May '16

Hi all, I don't want to add permission to manage a template, but I want to set permission to this template so as to each new vm created from this template inherits of the same permissions. Many thanks. -- Nathanaël Blanchet Supervision réseau Pôle Infrastrutures Informatiques 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr
