VMware exec: On free specs, virtualization's boost for Linux

Filed under
Interviews

VMware is opening up its virtual machine disk format specification, but today's news is about sharing, not open sourcing technologies.

VMware's decision to share at no cost its format specification with developers and vendors will spur big gains in virtualization innovation, according to Dan Chu, senior director of developer/ISV products for VMware, an EMC company in Palo Alto, Calif. Meanwhile, says Chu in this interview, virtualization is knocking down barriers to enterprise Linux and open source software adoption.

Why did VMware decide to share its core virtual machine disk format specification?

Dan Chu: People with large enterprise environments are fully standardizing on VMware; but they also depend on a whole set of key vendors -- like BMC and Symantec -- to provide other functions to do such things as manipulate, update, patch and back up data and systems.

The virtual machine format and specification defines everything from how the application operating system is encapsulated to how it is then put onto a data file system or local or network storage. Giving unrestricted access to the core formats and interfaces and APIs around virtualization lets any developer leverage and develop on top of virtualization. Their innovations will make server virtualization easier to deploy and manage and more highly optimized for customers.

Before this, you would have to either reverse engineer or enter into a very proprietary license that would be restrictive and inhibit development against virtualized environment. We want to make it fully open.

  • OpenShift Commons Gathering event preview
    We're just two months out from the OpenShift Commons Gathering coming up on November 7, 2016 in Seattle, Washington, co-located with KubeCon and CloudNativeCon. OpenShift Origin is a distribution of Kubernetes optimized for continuous application development and multi-tenant deployment. Origin adds developer and operations-centric tools on top of Kubernetes to enable rapid application development, easy deployment and scaling, and long-term lifecycle maintenance for small and large teams. And we're excited to say, the 1.3 GA release of OpenShift Origin, which includes Kubernetes 1.3, is out the door! Hear more about the release from Lead Architect for OpenShift Origin, Clayton Coleman.

Security News

  • Report: Linux security must be upgraded to protect future tech
    The summit was used to expose a number of flaws in Linux's design that make it increasingly unsuitable to power modern devices. Linux is the operating system that runs most of the modern world. It is behind everything from web servers and supercomputers to mobile phones. Increasingly, it's also being used to run connected Internet of Things (IoT) devices, including products like cars and intelligent robots.
  • security things in Linux v4.6
    Hector Marco-Gisbert removed a long-standing limitation to mmap ASLR on 32-bit x86, where setting an unlimited stack (e.g. “ulimit -s unlimited“) would turn off mmap ASLR (which provided a way to bypass ASLR when executing setuid processes). Given that ASLR entropy can now be controlled directly (see the v4.5 post), and that the cases where this created an actual problem are very rare, means that if a system sees collisions between unlimited stack and mmap ASLR, they can just adjust the 32-bit ASLR entropy instead.
