[Users] proper way to move nfs data storage domain?
by David Smith 21 Mar '14

21 Mar '14

Two examples; 1) I need to move the nfs data domain to a new server, whats the best way? 2) I think this applies the same as above, if I need to rename the nfs server hostname, whats the best way? I managed to "export/import" the export and iso domains and have them up and running on the new server, however, since you can't import a data domain, i'm wondering whats the best method for this. thanks

[Users] Clone from Snapshot
by Tejesh M 20 Mar '14

20 Mar '14

Hi, I'm trying to clone a VM from snapshot with the below code. but it is not cloning.. org.ovirt.engine.sdk.decorators.VM vm2 = api.getVMs().get("testVM"); VM cloneVM = new VM(); cloneVM.setName("MyClonedViaAPI"); VMSnapshot snap3 = new VMSnapshot(null); snap3 = vm2.getSnapshots().get(UUID.fromString("7799ce3f-a007-415a-84c5-df323e8f440d")); Action act = new Action(); act.setClone(true); act.setVm(cloneVM); snap3.restore(act); Actually, my original goal is to Clone VM directly from another VM instead of cloning from snapshot. Can you help me? -- Thanks & Regards Tejesh

[Users] Changing IP address of NFS storage server
by René Koch 20 Mar '14

20 Mar '14

Hi, I have an old oVirt 3.2 setup and I have to change the ip address of the data storage domain (NFS). Even if I shut down all vms I can't detach the data storage domain and reimport it as vms and templates are configured in oVirt which have their disk on this storage domain. Is there a way to change the ip? Maybe using the database? Would this be possible in 3.3 or 3.4? Thanks a lot for tips! -- Best Regards René Koch Senior Solution Architect ============================================ LIS-Linuxland GmbH Brünner Straße 163, A-1210 Vienna Phone: +43 1 236 91 60 Mobile: +43 660 / 512 21 31 E-Mail: rkoch(a)linuxland.at ============================================

[Users] Ovirt 3.3.3 to 3.3.4 upgrade issues Centos 6
by Gary Lloyd 20 Mar '14

20 Mar '14

I have tested an upgrade from engine 3.3.3 to 3.3.4 under centos 6. It seems that the vdsm nodes are now showing as non-operational and the only way I have been able to cure this was to: - Upgrade the vdsm version on a node to 4.13.3-4 - install vdsm-gluster - start glusterd service We are only currently using ISCSI. I cannot get a node running vdsm-4.13.3-3 to show as being operational under engine 3.3.4 Has anyone been able to get 3.3.4 functioning with previous version vdsm nodes ? This issue may hinder our progress when it comes time to upgrade our production engine / nodes when putting hosts into maintenance mode and performing migrations etc. Thanks *Gary Lloyd* ---------------------------------- IT Services Keele University -----------------------------------

The vm/hosts statistics are gathered and provided by VDSM. Anyway I would leave this part out at the moment. The virt-sparsify command is a long running task and in the current architecture it can be only an SPM task. There is some ongoing work to remove the pool and the SPM (making virt-sparsify operable by any host) but I wouldn't block on that. > I am also not very clear about the Shared Storage component in the > architecture.

The storage connections are already managed by vdsm and the volume chains are maintained transparently in /rhev/data-center/...

19 Mar '14

Hi, we are brainstorming on what should we change in the oVirt UI for 4.0. for current brainstorming phase, "anything goes" - i.e., I'd like us to ignore current limitations and flows, and envision/fantasize the "perfect solution". SO - what do YOU think we should consider for 4.0 UI concept, flows, etc. Thanks, Itamar

[Users] CPU: Westmere vs. Ivy Bridge
by Joshua Dotson 19 Mar '14

19 Mar '14

Hello, The nodes on the cluster I'm installing have Ivy Bridge CPUs<http://ark.intel.com/products/75790/Intel-Xeon-Processor-E5-2630-v2-15M-Cac…>. The latest choice I see in the hosted-engine installer is Westmere. Am I missing out on anything significant by choosing Westmere in this case? Is there any plan to add Ivy Bridge as an option? Even if there is no difference behind the scenes from choosing Westmere, having an Ivy Bridge option would have saved me the time it took to reverse engineer the need to look at the source code to the need for the CPU family: instruction sets (performance?). Thanks, Joshua

[Users] affects of changing compatibility setting on running cluster
by Charles Weber 18 Mar '14

18 Mar '14

Hi everyone, I believe I need to change my cluster compatibility level and would like to know if I can do this ona live cluster or if I have to change everything to maintenance mode first. I ran engine setup and upgraded to current engine level then tried to add a new node using the 3.3.4 el6 iso. This resulted in an error: Host x.x.x.x is installed with VDSM version (4.14) and cannot join cluster Default which is compatible with VDSM versions [4.13,4.9,4.11,4.12,4.10]. My current versions are: Engine 3.3.4-1.el6 at compatibiltiy version 3.2 2 Nodes running CentOS 6.4 with VDSM 4.10.3-0.36.23.el6 Am I correct that I need to change the compatibility version to 3.3? This has some production VMs, do I need to turn everything off first or is this a non-interruptive change? How will this upgrade affect my current 2 hosts at their version? My original idea was to migrate working VMs to new ovirt ISO node and then re-install original nodes to the same version off the 3.3.4 el6 iso. I appreciate any advice. Chuck

This wasn't my email, it was Eli Mesika's. I just remembered that he sent it so it was easy to find. I agree that the instructions are not complete. The database was created during setup - you were asked about that and probably accepted the defaults, which create a local database called 'engine'. You can connect to it by doing: su - postgres psql engine Obviously, do not change anything before you understand what you are doing and have some good backup.

[Users] migration of VM, which protocol actually works?
by aditya mamidwar 17 Mar '14

17 Mar '14

i wanted to learn about the modules so that i could understand how the engine POSTS and sends data to the backend sql database and other scripts to perform various options. for e.g i need to know which code actually collects the storage path for the ISO s during ISCSI storage domain setup. also how the hosts, clusters and data centers are made and stored at the backend. if i want to add a new UI that bypasses some of these complicated tasks (again for personal understanding), will I be able to do that. Also i would like to mention that am working on making a little changes to how the ISCSI protocol works.. My another doubt is: when are the NFS/ISCSI/FC protocols actually used in ovirt. like what part of the VM running state? are their purpose limited to just copying the ISO from the storage center to the path required by the Host. Are the protocols them self responsible for sending and getting data during VM execution on a node. The concept of node and migration has left me a little confused. since each node can run multiple VMs , so during the running/execution of the VM , do the network protocols actully work, if not , then how is that achieved. if yes, again my question arises, which module should i focus on regarding this issue. thanks -- -Aditya Mamidwar

[Users] Request for Wiki - dates
by Bob Doolittle 17 Mar '14

17 Mar '14

Hi, As most are aware, there's a lot of information on the Ovirt Wiki that's out of date. In spite of our best efforts, that will probably always be true - it's the nature of Wikis. When I look for information on our Wiki, I never know where the most current information is. I think it would be really helpful if someplace on each Wiki page was a useful date to let us know the currency of the info. Probably the most useful date is last-modified, although creation date might also be useful. Maybe we could even map/display the date to the version number of whatever the current stable release was at the time for context (sometimes the content of a page calls out a particular version it's addressing, but a lot of the time it does not). Just as an example, I want to find out about migrating my existing configuration to self-hosted, using 3.4 RC2. A google search shows the following links (in order shown): http://www.ovirt.org/Features/Self_Hosted_Engine http://www.ovirt.org/Migrate_to_Hosted_Engine http://www.ovirt.org/Hosted_Engine_Howto ... I'm sure the Features page is ancient at this point. It's hard to tell about the 2nd page. Of course the date a page was last modified doesn't directly indicate how correct/current the information is, but there's a correlation. Knowing the date would be useful in making a judgment. It might even help the task of identifying and cleaning up obsolete pages. Easy to do? -Bob

[Users] Migrate simple configuration to self-hosted
by Bob Doolittle 17 Mar '14

17 Mar '14

Hi, I want to migrate my existing deployment to self-hosted. I have a simple deployment: A: Machine Fedora 20 B: libvirt VM (hosted on A) RHEL 6.5 running Engine 3.3.4-1 C: Machine RHEL 6.5 acts as Hypervisor/Host/Node (VDSM 4.13.3-4) ISO NFS Domain is on B Data (Master) NFS Domain is on C I want to migrate VM B to Machine C, as self-hosted, and free up Machine A When I look at these instructions: http://www.ovirt.org/Migrate_to_Hosted_Engine It starts with "I installed a new host with fedora 19". I don't understand this. Won't most people doing this migration want to start with their existing Hypervisor/Host/Node, and migrate their Engine to it? Do I really need a new 3rd machine, when my goal is to free up one of my 2 existing machines? Or can I go ahead and assume these instructions are fine to apply to an existing Host already running VDSM 4.13.3-4? I would have (naively?) imagined that the typical migration would be something like: 0. Upgrade Engine and Host to 3.4 1. Create a new VM 2. Install OS on new VM, start it up 3. Backup current Engine 4. Stop current Engine (leave Host and VM running), change hostname (local and DNS), maybe power off for good luck until done 5. Login to new VM (probably using ssh unless there's a way to connect directly to the VM via Spice/VNC while the Engine is down) to: A. Assign previous Engine hostname to it (local and DNS), possibly reboot B. Set it up as a self-hosted Engine C. Restore backup to it D. Start up new engine What am I missing? Thanks, Bob

[Users] Ovirt 3.4rc + Qemu Live snapshot : Problem to delete a Snapshot
by Eric Bollengier 16 Mar '14

16 Mar '14

Hello, I upgraded to Ovirt 3.4rc allinone on centos6, and I compiled/installed the qemu-kvm-rhev to be able to take live snapshots. Taking the snapshot is OK, but I would like to delete them, and the button and the menu are disabled (grey) until I shutdown the VM. Once powered off, actions are available, and I'm able to delete snapshots. When looking the Snapshot Actions Matrix: http://www.ovirt.org/Live_Snapshots Is the "Revert" operation needed to delete a snapshot ? (Deleting a snapshot file implies to write changes from the snapshot file to the parent file, looks to be "Commit" for me). If not, should I have to upgrade something else, like libvirt, to be able to delete snapshots?
