Abstract: Technologies for managing paravirtual network device queue and memory of a network computing device that includes multi-core processor, a multi-layer cache, a host, and a plurality of virtual machine instances. The host is assigned a processor core of the processor and may be configured to copy a received network packet to a last level cache of the multi-layer cache and determine one or more virtual machine instances configured to process the received network packet. Each virtual machine instance has been assigned a processor core of the processor and has been allocated a first level cache of the multi-level cache memory associated with the respective processor core. The host is additionally configured to inject an interrupt into each processor core of the determined virtual machine (s) which indicates to the virtual machine instance (s) that the received network packet is available to be processed.

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.
