Abstract
The present application is directed to dynamic reassignment for multi-OS devices. An example device may comprise equipment, at least two operating systems, a kernel for each OS to provide an interface between the OS and the equipment and a virtual machine manager (VMM). OS selection agents in each OS may interact with a kernel mode controller (KMC) in the VMM. For example, the OS selection agent may transmit a message instructing the KMC to transition the foreground OS to the background and transition a background OS to the foreground. The KMC may transmit signals to the kernels of the foreground and background operating systems causing at least one driver in the foreground OS kernel to save a current equipment state and release control over the equipment while also causing at least one driver in the background OS kernel to restore an equipment state and to take control over the equipment.
