The document describes setting up a virtual machine environment using QEMU and DPDK to test the Lagopus software switch. Key details include: - Configuring a Supermicro server with Intel Xeon CPU and networking hardware for use as the host system. - Installing Ubuntu Server in a QEMU virtual machine and using DPDK and Pktgen tools for packet processing and testing. - Configuring two additional virtual machines to test the Ryu controller and Lagopus switch using bridged networking between VMs and the host system. - Providing configuration details for QEMU, virtual machine images and networking, CPU and memory settings to optimize for DPDK and packet processing
