01 Jan '12

The following summarizes the DR meeting from today Attendees: Backend Team + Moran & Haim from QA ----------------------------------------- => marks responsibility for action items.| ----------------------------------------- Issues/Action Items: 1) Video - memory allocation logic, check again why the logic of how much memory to allocate to a video device should move to backend. => (Eli, Igor) 2) Generic-device - rename to vm_device (Eli) 3) Verify hash is only on devices (not on all domxml) , check if can be expanded to VM scope (app list etc.) => (Eli, Igor) 4) Floppy/CD - should be handled as vm_device that means we have to add to it also boot order => (Eli, Igor) 5) Hot plug - need to check for added/deleted devices, Open issue how to handle for managed device. same for any other device that is changed not via backend => (Eli, Igor) 6) How boot order affects GUI (order of NICs) - check with Einav if support can be added for that in UI (for disks use only 1) (Eli,Einav) 7) OVF - add new devices , addresses , coordinate with V2V => (Eli) 8) Live snapshot , check if affects design => (Eli, Igor) 9) Review class diagram of detailed design => (Eli) 10) Do we have to persist indexes ? check if addresses are respected in spite of indexes.... => (Eli, Igor) 11) Update wiki pages => (Eli) Reference: http://www.ovirt.org/wiki/Features/Design/StableDeviceAddresses http://www.ovirt.org/wiki/Features/Design/DetailedStableDeviceAddresses

[Engine-devel] JBoss RPM vs JBoss zip file
by Ronen Angluster 29 Dec '11

29 Dec '11

Hello, I guess this discussion was being carried offline and i wanted to get the as many opinions as possible about this issue. Currently, we provide the users with 2 methods of handling JBoss AS's deployments: 1. Download the zip file from jboss.org and deploy it wherever the user wishes. 2. Install a specially crafted RPM that is designed & destined to work with the ovirt-engine's RPM set of files. (This is a temporary deployment phase that will end when jboss will release their own set of RPMs) in MHO, i think that the RPM deployment should be used ONLY when installing the ovirt-engine RPMs and not when using the ovirt-engine's git repository for development. especially since deployment to the file system of the host requires root permissions and this is not something that should be a consideration when you're developing code. I think that developers should use the JBoss zip package and deploy it locally, and NOT use the ovirt-engine-jbossas RPM. opinions? Ronen

[Engine-devel] vdsm checkConnectivity pitfals
by Roy Golan 26 Dec '11

26 Dec '11

Hi all, VDSM network provisioning api exposes a validity check to know the newly applied changes works. The actual check is comparing the /var/run/vdsm/client.log modified time to the time when the check began and repeats that check after sleeping 1 seconds for X time (where X is connectivityTimeOut) def clientSeen(timeout): start = time.time() while timeout >= 0: if os.stat(constants.P_VDSM_CLIENT_LOG).st_mtime > start: return True time.sleep(1) timeout -= 1 return False Main issues I spot are: 1. In case the host is in maintenance, the caller of the API must generate traffic, concurrently to running api call, and then must join and sync threads to realize when all is done. see http://gerrit.ovirt.org/#change,584 2. locally calling vdsClient also modifies the client.log - we can't rely on that no one will do that during the call. 3. Failure writing to the client log will fail network provisioning! All of the above makes it not very reliable as a check and harder to call, without posing races, as client. Possible alternate solution: 1. We can try to reach the api caller socket in return, maybe use http code 100 ? 2. pass in the API a URL which the VDSM will call. could be a health-check servlet or something similar. Any toughs?

[Engine-devel] Redunant class of ValueObjectMap ?
by Yair Zaslavsky 23 Dec '11

23 Dec '11

Hi all, Do we need org.ovirt.engine.core.common.queries.ValueObjectMap? Can we use a Java map class directly instead (we had to use this with SOAP WS in the past, prior to current rest-API days)? Yair

[Engine-devel] Patches that support jboss AS7
by Oved Ourfalli 22 Dec '11

22 Dec '11

Hey, I recently worked on making the proper changes to make the engine code work on Jboss AS7, and it works now! Still needs some testing and probably some more adjustments, but it looks promising. I pushed the commits to gerrit (the first one contains most of the changes, the others are fixes and additions): http://gerrit.ovirt.org/698 (POC - review, don't submit) engine: Jboss-as7 - base commit with jboss-as7 related changes http://gerrit.ovirt.org/699 (POC - review, don't submit) restapi: Jboss-as7 - fix rest api tests http://gerrit.ovirt.org/700 (POC - review, don't submit) engine: Jboss-as7 - Fix utilities to work with jboss as7 http://gerrit.ovirt.org/701 (POC - review, don't submit) engine: Jboss-as7 - Copying the correct jdbc jar to the modules directory I'd be happy to hear your comments. Most changes there were done due to problems I encountered, but feel free to suggest other solutions. Make sure you don't submit this patch yet, as it is a POC, and other changes are needed in order to complete the work on that. These patches work under the latest AS7 version (7.1.0.Beta1b) - http://download.jboss.org/jbossas/7.1/jboss-as-7.1.0.Beta1b/jboss-as-7.1.0.… (The patches currently work only on the version above, as one jar is replaced in the Jboss modules directory to solve LDAP issues). All the versions can be found in: http://www.jboss.org/jbossas/downloads I'm here if you have questions or comments. Thank you, Oved

[Engine-devel] API: exposing used/total for images and snapshots
by Geert Jansen 21 Dec '11

21 Dec '11

Hi Michael, i remember that previously we exposed both used and total size for VM images. Right now it seems the API is only exposing total but not used. The GUI is exposing used. Do i remember this correctly? A second question on snapshots: here i think we never showed used/total, and the GUI does not show this either. Do we track this data in the BE, or would this also require backend changes? Please let me know and i'll file the right BZs. Thanks, Geert
