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.
