by Sandro Bonazzola 19 Mar '14

19 Mar '14

The oVirt team is pleased to announce that the 3.4.0 Second Release Candidate is now available for testing. Release notes and information on the changes for this update are still being worked on and will be available soon on the wiki[1]. Please ensure to follow install instruction from release notes if you're going to test it. The existing repository ovirt-3.4.0-prerelease has been updated for delivering this release candidate and future refreshes until final release. An oVirt Node iso will also be available soon. We decided to postpone Final Release by one week in order to properly test the bugs fixed since last Release Candidate. Help us make this the best release ever, testing it yourself!

Do not see anything obvious. = All our hosts are running CentOS 6.5 & vdsm-4.13.3-4. Can you guys provide some pointers as to where to check for failure? Thanks in advance.

Hi, does it have any side effects if I change the password which protects the private root CA key ?

[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. You can read, and usually update, without taking the engine down. There is quite a lot of material on the ovirt wiki - please search and read a bit - e.g. for 'ovirt database'. Do not hesitate to ask (on-list) again if you have questions. You can also ask on irc for faster help.

[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
