A customer has an entry level Power System that is currently partitioned and managed by a Hardware Management Console （HMC）. For operational reasons， it must be disconnected from the HMC and configured as a new development system. How should the customer proceed to implement PowerVM Express and Integrated Virtualization Manager （IVM） on this Power System？ （）

A. Install a VIO server as an additional partition and DLPAR the resources from the existing partition to the VIO server.
B. Create a service partition and install a VIO server. This will automatically move resources to the VIO server on reboot of the managed system.
C. Delete all the existing LPARs， create a new LPAR and assign all the system resources to this LPAR and then install the VIO server on this LPA
D. Reset the machine to Manufacturing Default Configuration and install the VIO server on the resulting partition created， which will own all system resources.
