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’s Xen implementation uses a different disk format for virtual machines than
open source Xen, so live migration of virtual machines will not work between the existing
Xen implementation and Oracle VM.
B.
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 of communicating in this manner.
C.
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.
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.
