A customer is running an existing server farm of open source Xen servers running the same version of Xen as Oracle VM 2.2. The customer would like to manage these servers with Oracle VM.
What is the best reason that this will not be possible?

A. Oracle VM employs a layer of technology on top of Xen that enables remote management through Oracle VM Manager or Oracle Enterprise Manager. The existing Xen servers are incapable ofcommunicating in this manner.

B. Oracle VM uses a forked Xen distribution, so although the version numbers are the same, the behavior of the virtual machines at run time will be different.

C. Oracle VM's Xen implementation uses a different disk format for virtual machines than open source Xen, so live migration of virtual machines will notwork between the existing
Xen implementation and Oracle VM.

D. Oracle VM uses a highly proprietary protocol format for Live Migration that enables strongencryption. Standard Xen servers will not be able to live migrate to the Oracle VM servers, or vice versa.
