Abstract: This is a time where usage of technology keeps growing. Along with a growth of using technology, so as it needs to increase the using hardware and server. It consumes more energy than past. As a solution virtual environment can be used to ease the usage and less hardware, server and energy consume. More than one Virtual Machine (VM) in a host can be run at once but virtual traffic between two VMs will never go out of the host. Therefore, this network traffic will never meet a physical firewall and also when data comes from outer networks must be filtered before they enter the related VMs. In case of that a Virtual Firewall (VF) must be deployed. When a network traffic generated it causes VF to slow it’s mechanism down as well as the hypervisor’s performance. To solve it, quantum mechanism approach will be used and will be given a solution to improve the VF performance as well as hypervisor performance.
