Abstract—Nowadays the need for information technology
is growing rapidly , especially the need for a server as a
medium for the passage of an application , in addition ,
there are constraints of the most important in the
utilization of information technology at this time that the
resource requirements are not cheap and space
constraints, it is necessary utilization of resources as much
as possible. Virtualization as a part of information
technology is expected mamapu overcome the existing
problems. If seen as part of an overall trend in a particular
company PT. PLN (Persero) which use autonomic
computing, a scenario in which wherein the IT
environment will be able to manage itself based on
perceived activity and utility computing, where processing
power omputer considered a utility that clients can pay
only used alone. Implementation of virtualization with
Citrix XenServer based on Linux itself aims to centralize
administrative tasks to improve scalability and also as part
of the company's efficiency. The methodology used for this
study is NDLC which has 6 phases namely, analysis,
design, prototype simulation, implementation, monitoring
and management, with the implementation of this system
deiharapkan able to meet the needs of corporations.
