  HIDE ANSWER

In creating a new virtual machine, by using a virtualization software, a user is able to do following EXCEPT:

• hardware settings such as how much memory the VM should have.

• what hard disks should be virtualized through which container files and what CDs are mounted,

• divide the operating system into multiple versions based on latest update.

• state information whether the Virtual Machine is currently running and saved its snapshots.

Define the role of virtualization in cloud computing?

• It removes operating system inefficiencies

• It improves the performance of web applications.

• It optimizes the utilization of computing resources.

• It adds extra load to the underlying physical infrastructure and has no role in cloud computing.
