To VT-D or Not to VT-D? A guide on whether to Utilize Direct Device Attach in your Virtualized System?Intel VT-D Direct Device Attach allows a Virtual Machine to control an entire PCI-E device (e.g. NIC) while bypassing any VMM interference. The performance benefit will be a dramatic reduction in CPU utilization, but the precise gain will vary.
Designing low power virtualization solutions has become very important for extending the battery life of mobile systems. This paper reports the power profile of leading desktop virtualization solutions under idle and workload conditions.
This article walks you through configuration of OVS with DPDK for inter-VM application use cases. Create an OVS vSwitch bridge with two DPDK vhost-user ports, each connected to a separate VM, then use a simple iperf3 throughput test to evaluate performance.
This article presents a firewall for OpenStack’s Neutron project that is based entirely on Open vSwitch rules. The firewall is based on "learn action" and uses the same public API to talk to the Neutron agent as the existing Linux Bridge firewall implementation, making it a straight swap for people already using OVS.
