Parallels patches the Linux kernel. Habrainterview with Stas Protasov

For many years, Parallels (developer of software for virtualization) is one of the active contributors of the Linux kernel (see the Linux Foundation report for 2012 ). The company's contribution to the Linux kernel is commensurate with the workload of Google, AMD, Cisco and HP. Implemented:

• namespaces for the network environment, process identifiers (PID), interprocessor communication (SysV IPC), etc .;
• advanced capabilities for managing container resources (memory, processor, disk, etc.);
• “Freezing” the state of containers and resuming their work with a minimum of nuclear modifications (used for live migration of containers from one physical server to another) - project criu.org;
• support for network file system NFS in containers.

Stas Protasov, co-founder of Parallels and the head of the whole development, will answer the questions of masters. Publish them in the form of comments to this topic, preferably in the format of "one question - one comment," according to tradition, each author of the question gets a plus in karma.

Here are a couple of events that have happened in Parallels over the past six months. Maybe some of them are interesting to habrashchitelami - on these topics, you can also ask questions.

1) The company has released software created with Skolkovo money . This software - Parallels Automation for Cloud Infrastructure (PACI) - implements for providers a functionality similar to Amazon EC2. PACI is already for sale in the world.
')
2) Parallels has opened the third development center. This time in St. Petersburg.

3) The implementation of the Applications Packaging Standard (APS) , developed by Parallels several years ago for the sale of third-party web applications, continues. There are already over 2 million downloads of APS services.

The answers of Stas Protasov will be published as a separate article a few days after the end of the reception of questions. Ask!
