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.

Raspberry Pi imitator has GbE, 2GB RAM, and 4K video

Asus has launched a RPi-like “Tinker Board” that runs Debian and Kodi on a quad-core 1.8GHz -A17 RK3288, and offers 2GB RAM, GbE, 4K video, and 40-pin GPIO. The rumored Asus Tinker Board is finally for sale at Farnell in the UK, with a footprint, layout, and features that are very close to that of the Raspberry Pi, including the much copied 40-pin expansion connector and a Debian Linux image. The quad-core SoC and onboard wireless further reminds one of the Raspberry Pi 3. Read more

FastComputer: Fussy but Fixable

Let's assume that the developer soon will issue an updated or fixed version so the Network Manager will work outside a Virtual Machine window. That will give FastComputerLinux a shot at being more useful to those who want a good out-of-the-box simple OS solution. I am not sure that this distro's name is an indication of speedy performance. I tested it on several machines looking for speed. As expected, the live session DVD was very sluggish. It was much peppier on the VM. I was expecting a little bit better speed performance on my test gear with a hard drive installation. Read more

Linux Kernel 4.9.5 Released with Updated Radeon Drivers, KVM and PPC Fixes

A new maintenance update of the Linux 4.9 kernel series was announced today by renowned Linux kernel maintainer and developer Greg Kroah-Hartman, versioned 4.9.5. Coming only five days after the previous point release, Linux kernel 4.9.5 appears to be a big milestone that changes a total of 132 files, with 1515 insertions and 821 deletions. There are numerous improvements implemented in this fifth Linux 4.9 maintenance update, but first we'd like to remind you that Greg Kroah-Hartman recently marked this kernel branch as long-term supported (LTS), yet this is not apparent from kernel.org.
