The rapid development of technology leads to improvement in a variety of computing concepts, information and communication technology(ICT). The ICT environment is become more complex and costly. Cloud Computing is one of phenomenon in the new ICT services, Cloud Computing model has three categories of services : Infrastructure As A Service (IAAS), Platform As A Service (PAAS), Software As A Service (SAAS). It also has four deployment models which are private cloud computing, community cloud, public cloud and hybrid Cloud. This research aims to determine the overhead of the virtualization environment. It is expected the private cloud with virtual technology, that utilizes the maximum resources does not degrade server scalability. The implementation of private cloud is using OpenStack with configuration multiple interfaces multiple servers. This results indicate that the overhead of a single virtual machine is 114 ms (database server) and 212 ms (webserver), to ten virtual machines are active 615 ms (database server) and 786 ms (webserver). Overhead that occurs on a single VM can still be neglected, despite the performance degradation with increasing number of active virtual machines the execution time of servers application tends to be linear close to shape belongs to the physical servers.
