You caught us doing some quick maintenance, temporarily restricting your repository to read-only access. About xNBD is yet another NBD (Network Block Device) server program, which works with the NBD client driver of Linux Kernel. xNBD provides the following features
Docker networking is fast evolving. There are many options today for using Linux bridge, port mapping, Open vSwitch for this purpose. See our presentation on the different options available, and especially how to network containers across multiple hosts. We found the need to have a comprehensive mechanism to network all applications across hosts with isolation through overlay networking. The loris
Daily Dilemma Recently I’ve been finding myself in various conversations about Docker and Linux Containers (LXC). Most of the time the conversations eventually end up with one and the same question and that is whether we should run containers in production. Initially this post had a few paragraphs where I philosophised about readiness of the technology, but I’ve deleted those paragraphs now as the
Paravirtualized drivers for kvm/Linux Virtio was chosen to be the main platform for IO virtualization in KVM The idea behind it is to have a common framework for hypervisors for IO virtualization The specification can be found here: https://docs.oasis-open.org/virtio/virtio/v1.2/virtio-v1.2.html
This page provides an introduction to the common networking configurations used by libvirt based applications. This information applies to all hypervisors, whether Xen, KVM or another. The two common setups are "virtual network" or "shared physical device". The former is identical across all distributions and available out-of-the-box. The latter needs distribution specific manual configuration. Ho
This document discusses different methods for virtualizing I/O in virtual machines. It covers virtual I/O approaches like virtio, PCI passthrough, and SR-IOV. It also explains the role of the VMM/hypervisor in managing I/O between VMs and physical devices using techniques like VT-d, Open vSwitch, and single root I/O virtualization. Finally, it discusses emerging standards for virtual switching lik
先日、株式会社ハートビーツさんが主催されている勉強会、hbstudy#27にて弊社クラウドサービスのネットワーク構成について発表を行いましたので、そのご報告です。 今年11月中旬に石狩データセンターの開所にあわせてクラウドサービス（さくらのクラウド）をリリース予定です。 そのネットワークの構築を私の方で担当しており、こちらの勉強会では、ネットワーク全体のアーキテクチャ、ネットワーク機器評価試験の際にはまりやすい（はまった）ポイント、今後の展開について説明をさせていただきました。
