Intel® Graphics Virtualization Technology (Intel® GVT) is an extension of Intel® Virtualization Technology (Intel® VT) for Directed I/O (Intel® VT-d) that provides hardware accelerated I/O virtualization support for Intel® HD graphics - it is one of the GPU virtualization solutions. Intel GVT allows the Virtual Machine (VM) to call a GPU function via I/O. Only one VM can use the GPU at a given...
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.

The networking world is rife with buzz words like SDN, NFVs, Cloud, and Virtualized everything for network switches, routers, firewalls, load balancers, web servers, and other communication functions. Commodity NICs can replace expensive, specialized hardware devices for much less cost and can easily be reconfigured as requirements change. When you are ready for SDN/NFV, where to start, what to...
OpenStack is a virtualization environment supported by several operating systems. Over the years, Linux* distributions have become easier to install and configure, however, despite these improvements, installing an OS on a server is still time consuming. This series of blogs shows the steps to setup a bare metal deployment providing a reliable installation framework using containers.
This is the second post in a series of blogs about how to configure and deploy a bare metal controller using Ironic
This is the third post in a series of blogs about how to configure and deploy a bare metal controller using Ironic.
This article shows step-by-step how to install DevStack on CentOS* 7 for those who are new to OpenStack.
When running in a virtual machine, you may never be sure which physical CPU you are running on - hypervisor can pass anything as CPUID to guests. For best performance, it helps to use the best instruction set supported by a physical CPU - be it AVX512, AVX2, AVX, SSE4.1, AES-NI, or other accelerated instruction sets. Enhanced Platform Awareness features use top-down approach to close this gap,...
