Introduction to Linux interfaces for virtual networking | Red Hat Developer
Linux has rich virtual networking capabilities that are used as basis for hosting VMs and containers, as well as cloud environments. In this post, I will give a brief introduction to all commonly used virtual network interface types. There is no code analysis, only a brief introduction to the interfaces and their usage on Linux. Anyone with a network background might be interested in this blog pos

Macvlan and IPvlan basics
Macvlan and ipvlan are Linux network drivers that exposes underlay or host interfaces directly to VMs or Containers running in the host. In this blog, I will cover basics of macvlan and ipvlan, compare macvlan and ipvlan to Linux bridge and sub-interfaces and also show how to create these interfaces in Linux system. In the next set of blogs, I will cover how macvlan and ipvlan interfaces are used
Bridge vs Macvlan
Bridge A bridge is a Layer 2 device that connects two Layer 2 (i.e. Ethernet) segments together. Frames between the two segments are forwarded based on the Layer 2 addresses (i.e. MAC addresses). Although the two words are still often used in different contexts, a bridge is effectively a switch and all the confusion started 20+ years ago for marketing purposes. Switching was just a fancy name for
macvlan の使い方と挙動のメモ - Qiita
ソースは CentOS 7.0.1406 (3.10.0-123.el7.x86_64) で private モードの流れを確認した。 macvlan とは 実 NIC の上に仮想的な NIC 作る機能。 作成した仮想 NIC には任意の MAC アドレスを設定できる。 keepalived の仮想 MAC アドレス機能の実現に使われている。 LXC でもコンテナ用の仮想 NIC として使われている。 Kernel Documentation で触れられていないようだがマイナーな存在なのだろうか？ Virtual switching technologies and Linux bridge の 6-10 ページあたりが参考になる。 4つのモードがあるが、private か bridge を使うことが多そう。 private vepa bridge passthru 設定によっては mac
Macvlan vs Ipvlan
I’ve covered macvlans in the Bridge vs Macvlan post. If you are new to macvlan concept, go ahead and read it first. Macvlan To recap: Macvlan allows you to configure sub-interfaces (also termed slave devices) of a parent, physical Ethernet interface (also termed upper device), each with its own unique MAC address, and consequently its own IP address. Applications, VMs and containers can then bind
Four ways to connect a docker container to a local network
Update (2018-03-22) Since I wrote this document back in 2014, Docker has developed the macvlan network driver. That gives you a supported mechanism for direct connectivity to a local layer 2 network. I’ve written an article about working with the macvlan driver. This article discusses four ways to make a Docker container appear on a local network. These are not suggested as practical solutions, bu
Some notes on macvlan/macvtap « \1
There's not a lot of documentation about these interfaces. Here are some notes to summarize what I've been able to gather so far. Surely there's more to it (corrections and/or more information welcome). Macvlan interfaces can be seen as subinterfaces of a main ethernet interface. Each macvlan interface has its own MAC address (different from that of the main interface) and can be assigned IP addre
