Unable to change compatibility version due to hosted engine
by Renout Gerrits 15 Dec '16

15 Dec '16

Hi All, We have an environment which we want to upgrade to ovirt 4.0. This was initially installed at 3.5, then upgraded to 3.6. Problem we're facing is that for an upgrade to 4.0 a compatibility version of 3.6 is required. When changing the cluster compatibility version of the 'Default' cluster from 3.5 to 3.6 we get the error in the gui: "Cannot change cluster compatibility version when a VM is active. please shutdown all VMs in the cluster." Even when we shutdown all vm's, except for the Hosted Engine we get this error. On the hosts a 'vdsClient -s 0 list' is done which will return the HE. In the engine logs we have the following error: "2016-12-08 13:00:18,139 WARN [org.ovirt.engine.core.bll.storage.UpdateStoragePoolCommand] (default task-25) [77a50037] CanDoAction of action 'UpdateStoragePool' failed for user admin@internal. Reasons: VAR__TYPE__STORAGE__POOL,VAR__ACTION__UPDATE,$ClustersList Default,ERROR_CANNOT_UPDATE_STORAGE_POOL_COMPATIBILITY_VERSION_BIGGER_THAN_CLUSTERS" So problem would be that the HE is in the Default cluster. But how does one change the compatibility version when the HE is down? I've tried shutting down the engine, changing the version in the DB: "UPDATE vds_groups SET compatibility_version='3.6';" and starting the engine again. When I do that and try to start a VM: 2016-12-09T13:30:21.346740Z qemu-kvm: warning: CPU(s) not present in any NUMA nodes: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 2016-12-09T13:30:21.346883Z qemu-kvm: warning: All CPU(s) up to maxcpus should be described in NUMA config 2016-12-09T13:30:21.355699Z qemu-kvm: "-memory 'slots|maxmem'" is not supported by: rhel6.5.0 So that change was rolled back to compatibilty 3.5. After that we we're able to start vm's again. Please note that all hosts and HE are EL7. To me this doesn't seem like a strange set-up or upgrade path. Would it be possible to start the HE in another cluster than Default or is there a way to bypass the vdsClient list check? What is the recommended way of upgrading the HE in this case? Kind regards, Renout

dedicated gluster storage network
by Nathanaël Blanchet 15 Dec '16

15 Dec '16

Hi, I changed the previous all in one network to a dedicated gluster storage at the network level. But when doing netstat (or gluster peer status), I can see that listening connection still use the previous vlan and gluster bricks are probed on this vlan. I detached them with ovirt or manually to probe them an other time, but they are still probed on the initial ovirtmgmt vlan. What is this gluster network supposed to do in reality? -- 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

Check your network configuration of the manager. I had the same issue and i solved by adding a secondary NIC to the manager VM in the same network as the NFS storage (172.16.8.x in your setup).

Dear all, I'm currently trying to create a puppet module for setting up ovirt from scratch.

No idea, but it might be possible using affinity rules and/or HA. Changing the subject, to try to attract more relevant responses, and adding Tomer. Best, -- Didi

ovirt, spice and igel
by Craig Warner 14 Dec '16

14 Dec '16

I’m new to overt and this has been a rapid learning curve, and come to point where I need assistance. The objective of this project is to provide via a igel thin client a seamless multimedia experience for the end user. The environment is based upon both host and virtual instance using Centos 7.2 and ovirt 4.0. The igel thin client is designed to use the RHEV spice environment, so this is the first point of pain for this project. I can only the igel client to interact with the associating the firefox then finding the virt-viewer binary with the igel operating system. Not very seamless to provide multimedia experience for the end user. igel terminal is running the latest update. I’ve also engaged igel technical support but centos 7.2, and ovirt 4.0 seems to be breaking new ground. Next point of pain is performance of multimedia on the thin client, less then satisfactory experience. Once again any helpful suggestions would be appreciated. If I’ve left anything out in the description of what trying to achieve, let me know, and shall fill in the gaps. Once again any assistance would be appreciated. Craig
