I think should be version = version +1; 2. Now the quartz is automatic process, updateVmInSpm it is spm operation -it means it can trigger a reconstruct and spm election. 3. How your solution is handling a case of hotPlug/hotUnplug/remove/add of vm disks. vm_static is not usually updated. 4. Reconstruct/Recovery - updateVmInSpm should be called on all vms, no matter if they were updated. > > Regards, > > Mike > > > > ----- Original Message ----- > > > http://wiki.ovirt.org/wiki/Feature/OvfAutoUpdater > > > > > > Hi all, i'll be glad if you could review the wiki page of > > > OvfAutoUpdater, if you have any suggestions or ideas please let > > > me > > > know. > > > > > > http://wiki.ovirt.org/wiki/Feature/OvfAutoUpdater > > > > > > short preview from the wiki: > > > vm/template configurations (including disks info) are stored on > > > the > > > master storage domain for backup purposes, import/export and also > > > to > > > provide the abillity to run VMs without having a running > > > engine/db. > > > Currently ovf update is done synchronously when performing > > > various > > > operations on vms/templates - update, save, adding/removing a > > > disk, > > > etc. What's more, currently updating the ovf (updateVM vdsm call) > > > is > > > usually done within a transcation. > > > > > > The idea behined OvfAutoUpdater is to perform batch ovf update > > > operations that aggregate all outstanding updates per data > > > center. > > > These updates will be done in specifed time intervals which will > > > reduce XML-RPC calls and will enable the removal of this > > > syncronous > > > vdsm call from all over the code. > > > > > > Thanks, > > > Liron Aravot. > > > _______________________________________________ > > > Engine-devel mailing list > > > Engine-devel@ovirt.org > > > http://lists.ovirt.org/mailman/listinfo/engine-devel > > > > > > _______________________________________________ > Engine-devel mailing list > Engine-devel@ovirt.org > http://lists.ovirt.org/mailman/listinfo/engine-devel >
