This present invention relates to a method for using hypervisors to enable stable wireless network connections. The crux of the invention involves pushing the control of the networking devices from the Operating System level down to a networking front end hypervisor level. The hypervisor will control all networking devices, the authentication for these devices, and the selection of which connection to use. The hypervisor will also perform Network Address Translation (NAT) to the Operating System. Thus, the Operating System will receive a single, private IP address for use with the Operating System's applications. The hypervisor will handle the change of the IP address when roaming between networks and hide it from the Operating System through the use of the NAT.

The invention provides a bottom virtualization process (namely, virtualization for an operating system layer). According to a method, virtualization is realized by adding a virtual server function in an operating system layer. The bottom virtualization process comprises the following steps of: forming a virtualized layer on a hardware layer, thereby finishing virtualized integration of physical equipment; installing a plurality of client operating systems on the virtualized layer; and running an application program in the client operating systems. The client operating systems are communicated with the hardware through a VMM (Virtual Machine Monitor) in the virtualized layer, wherein the VMM is used for determining the access of all virtual machines to physical resources. In a virtualization solution, the VMM plays a role of a traditional operating system in a software set and the traditional operating system as the client operating system runs on the virtualized layer at a position of the application program. Compared with other virtualization processes, the bottom virtualization process has the advantages that a manager need not install and maintain a single operating system embodiment for each application, thereby lowering the management cost.

A computing device operates in a secure operating mode in response to user selection. Computer hardware is initialized to verify a bootloader of an operating system, and the bootloader verifies the operating system kernel. The kernel then verifies operating-system level executable files. After verification, a limited set of the verified files is loaded into a portion of the memory that is subsequently marked by the kernel as read-only. These files are executed to provide a basic Internet browser session; all other files are identified as non-executable. When the user accesses an authorized website and conducts a transaction that requires a user to provide information, the information is encrypted during transmission of the network. In addition, such information cannot be accessed by other parties since the information provided is not persisted at the computing device.
