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.

Abstract: Various embodiments are generally directed to techniques for improving the efficiency of exchanging packets between pairs of VMs within a communications server. An apparatus may include a processor component; a network interface to couple the processor component to a network; a virtual switch to analyze contents of at least one packet of a set of packets to be exchanged between endpoint devices through the network and the communications server, and to route the set of packets through one or more virtual servers of multiple virtual servers based on the contents; and a transfer component of a first virtual server of the multiple virtual servers to determine whether to route the set of packets to the virtual switch or to transfer the set of packets to a second virtual server of the multiple virtual servers in a manner that bypasses the virtual switch based on a routing rule.
