Is it possible to modify a template and populate the changes to the vms deployed from the template already?

Solution Unverified - Updated -

Issue

  • Is there a mechanism that enables us to modify a template? All the changes which is done on the template, should be replicated to the VMs which are provisioned from the template.

Eg, A template was created using RHEL6.1 vm. Once RHEL-6.2 is released, we need to access the template, do "yum update" and update it to RHEL-6.2 so that all vms deployed from the template will get automatically updated to 6.2?
