    mqnic - virtual link layer for qemu/kvm

    Low latency, high bandwidth IP for virtual machines

    MQNIC ( Message Queue NIC ) Virtual Link Layer The Message Queue NIC project provides a virtual link layer for qemu/kvm based virtual machines. The virtual link layer provides transport using the Apache ActiveMQ message server or other message bus and eliminates the need for external IP infrastructure to support VM deployments. Based on the ivshmem technology originally developed by Cam Macdonell the mqnic drivers use zero copy vm<->host data transfers and the apache message server to provide low latency, high bandwidth IP support for virtual data centers while simplifying the provisioning of hosted IP. Because the Message Queue NIC appears as a standard IP device on the target machine the integration of MQNIC and traditional IP routing is completely managed by the standard IP routing tools and infrastructure. Transport security is handled by the MQ server which supports multiple levels of encryption and authentication.
