[Users] Multiple Engines, one web Interface?
by Darrell Budic 18 Dec '13

18 Dec '13

Now that we’ve got a self hosted engine, has any one given any thought to allowing one engine to remotely control another? The scenario I’m imagining has one cluster at a DC with 4 nodes, and another cluster at a different DC with 3 nodes. Connectivity is normally pretty good, but it’s been known to drop for a bit every year. And I wouldn’t want to have the engine polling across it all the time as it’s a lower bandwidth link (100M vs 10G between nodes, so a bit). But what I would like is to have the one I’m sitting next to be able to control the remote one, and monitor it’s status, with each having it’s own self hosted engine so they are independent and migrations, etc, will continue to happen even if the two clusters get disconnected. This keeps all the polling local and fast, and avoids engine or cluster freak outs if/when the link is down between the two physically diverse clusters. Cool bonus feature would be to enable a direct transfer between the two clusters storage facilities. Maybe with a “transport VM” button that suspends it to disk and moves it before restarting it (assuming you built your networks right, of course, complex but presumably possible), but I’d with a simple way to copy a shutdown VM over without going through an export/import process. I could see this working with a separate manager engine, or just as an add in to the standard engine. Maybe a “cluster w/ local engine” type thing showing in the GUI. Obviously two web interfaces on two separate engines aren’t a terribly hard thing to manage, but I just imagined the simple way and figured I’d throw it out there and see how hard or easy people thought it might be. -Darrell

[Users] web documentation suggestion
by Darrell Budic 18 Dec '13

18 Dec '13

Would it be possible to start adding the Ovirt version a feature became available in to the various Features pages? This one as an example: http://www.ovirt.org/Features/Non_plugin_console_invocation I was going to test this and it took me a few moments to remember it was added in 3.3 and I was still running 3.3 when the listed commands returned errors. -Darrell

[Users] Physical CDROM access
by Bob Doolittle 17 Dec '13

17 Dec '13

Hi, With VMware ESX, when you edit the CD device you have of course the option of attaching an ISO, but IIRC you also have the option of selecting the physical CDROM device for the Host. There seems no way to do this with oVirt. It would be a really nice addition to the "Change CD" menu to have something like "/dev/cdrom". Is there a technical issue preventing this? Of course that would prevent VM migration such as HA while the CDROM device is attached, but that didn't stop VMware and it would be a valuable addition. Thanks, Bob

yes my idea is to start with 1 node ( storage+compute ) and then expand with more server to add storage and compute. what do you think ? >----Messaggio originale---- >Da: vbellur(a)redhat.com >Data: 16/12/2013 8.38 >A: "tristano82(a)libero.it"<tristano82(a)libero.it>, <users(a)ovirt.org> >Ogg: Re: [Users] How to - gluster > >On 12/15/2013 10:30 PM, tristano82(a)libero.it wrote: >> i have 1 phisical node with SSD disks, can i install ovirt with glusterFS >> storage as backend .

[Users] feature request - support getting console.vv with a single click
by i iordanov 17 Dec '13

17 Dec '13

Hi guys, Mobile browsers usually reserve the double-tap functionality for zooming in/out. It's therefore difficult/impossible to obtain a console.vv file from the user-mode web interface on a mobile device. Would you consider adding functionality to connect to the console without a double-click? Thanks! iordan -- The conscious mind has only one thread of execution.

[Users] Polling vs Pushing engine events
by Sven Kieske 17 Dec '13

17 Dec '13

Hi, we got the following problem: we create / start / stop hole vms /data centers / storage etc (basically: everything ovirt can handle via REST-API) But if you want to know e.g. the status of a vm (or anything) you need to constantly poll the API. This is not what we desire to do, as it does not scale very well (e.g. polling 100 vms). Is there a standardized way of pushing information from the engine? -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.

[Users] Hosts going offline due to storage issues.

Hi there I've got a 3 node oVirt 3.3.1 setup connecting to an Equallogic iSCSI SAN array.

[Users] AcquireHostId problem

Context : vdsm-4.13.0-11.fc19.x86_64 sanlock-2.8-1.fc19.x86_64 Creating storage domain (NFS) fails with error in engine.log such as Error code AcquireHostIdFailure and error message VDSGenericException: VDSErrorException: Failed to CreateStorage And Cannot acquire host id: ('b4f05e3e-d714-45c4-adf9-8d269418338f', SanlockException(-203, 'Sanlock lockspace add failure', 'Sanlock exception')) Reading the mail archive, I can see that this is a know issue but I do not see the workaround. Can someone enlight me ? Also, is there somewhere a coherent instruction set in order to make NFSv3 work (including iptables settings). I had to stop iptables to unblock myself...
