IP Instances - Network Virtualization for Solaris Containers, aka. zones

The IP Instance project just integrated into the Solaris Nevada code base and is supposed to be available in a Solaris 10 update later this year. Donghai Han, Yukun Zhang, Zhijun Fu and Erik Nordmark worked really hard on the development side to make this happen, George Yao and Alex Peng did the same on the test development side. IP Instances provides Solaris customers the option of assigning seperate IP stacks to Containers thus providing much more flexibility. IP Instances addresses a long list of customer enhancement requests and takes networking in Solaris Containers to the next level: With IP Instances you get full separation of the networking stack between Containers. With project Crossbow we'll extend network virtualization into the device driver layer and provide a industry-leading network virtualization solution. Crossbow is still in the works, but a beta version is already available on OpenSolaris. We are planning on starting a formal beta program in the next couple of weeks.

Great news! This was a feature really necessary for complex virtualization / consolidation scenarios. Had a lot of (routing) trouble using VLAN tagged interfaces with zones (to separate traffic). Will it be included in build 57 already? Cheers, Martin
