Fro-Xen no longer: Xen project plans shorter dev process

Let it go, let it go, says new overseer of open source hypervisor


The new release manager for version 4.6 of the open source Xen Hypervisor has proposed changes to the project's development process that he hopes will speed things up.

Citrix employee Wei Liu, who has scored the gig of ushering the next version into the world, has explained the new plan in a post, presentation and mail in which he outlines his intentions for this release.

The reason for the changes is that the last version of Xen required eleven months of work, two more than Xen aims for between releases. That's obviously not helpful or desirable, so Liu wants to speed things up and nail this release.

To do so, he suggests a feature freeze on July 10th, ahead of an October 9th launch. That freeze will be rather longer than was the case for work on Xen 4.5.

How things worked on Xen 4.5

Liu reckons a shorter “soft” freeze will do the trick as the long freeze for 4.5 “made upstreaming new features harder for contributors -- they need to rush to get their features at least posted in development window, then argue for whether it's OK to get in after soft freeze; Otherwise they risk waiting several more months.”

The new arrangements above, Lui feels, mean “we have shorter time in freeze and lead to possible less harden code. But I don't really see that as a big issue, given that we a) we still set aside 3 months for it, b) we only need to harden existing code.”

He also feels it will mean “no more arguing whether a feature should go in after freeze.”

In other words, once the project's Fro-Xen, it's time to Let It Go if you want any new features. At least until the sequel, which in Xen's case will emerge in 2016. ®

    Fine-print crucially deemed contractual agreement as well as copyright license in smartTV source-code case

    The Software Freedom Conservancy (SFC) has won a significant legal victory in its ongoing effort to force Vizio to publish the source code of its SmartCast TV software, which is said to contain GPLv2 and LGPLv2.1 copyleft-licensed components.

    SFC sued Vizio, claiming it was in breach of contract by failing to obey the terms of the GPLv2 and LGPLv2.1 licenses that require source code to be made public when certain conditions are met, and sought declaratory relief on behalf of Vizio TV owners. SFC wanted its breach-of-contract arguments to be heard by the Orange County Superior Court in California, though Vizio kicked the matter up to the district court level in central California where it hoped to avoid the contract issue and defend its corner using just federal copyright law.

    On Friday, Federal District Judge Josephine Staton sided with SFC and granted its motion to send its lawsuit back to superior court. To do so, Judge Staton had to decide whether or not the federal Copyright Act preempted the SFC's breach-of-contract allegations; in the end, she decided it didn't.

  • US brings first-of-its-kind criminal charges of Bitcoin-based sanctions-busting
    Citizen allegedly moved $10m-plus in BTC into banned nation

    US prosecutors have accused an American citizen of illegally funneling more than $10 million in Bitcoin into an economically sanctioned country.

    It's said the resulting criminal charges of sanctions busting through the use of cryptocurrency are the first of their kind to be brought in the US.

    Under the United States' International Emergency Economic Powers Act (IEEA), it is illegal for a citizen or institution within the US to transfer funds, directly or indirectly, to a sanctioned country, such as Iran, Cuba, North Korea, or Russia. If there is evidence the IEEA was willfully violated, a criminal case should follow. If an individual or financial exchange was unwittingly involved in evading sanctions, they may be subject to civil action.

  • Meta hires network chip guru from Intel: What does this mean for future silicon?
    Why be a customer when you can develop your own custom semiconductors

    Analysis Here's something that should raise eyebrows in the datacenter world: Facebook parent company Meta has hired a veteran networking chip engineer from Intel to lead silicon design efforts in the internet giant's infrastructure hardware engineering group.

    Jon Dama started as director of silicon in May for Meta's infrastructure hardware group, a role that has him "responsible for several design teams innovating the datacenter for scale," according to his LinkedIn profile. In a blurb, Dama indicated that a team is already in place at Meta, and he hopes to "scale the next several doublings of data processing" with them.

    Though we couldn't confirm it, we think it's likely that Dama is reporting to Alexis Bjorlin, Meta's vice president of infrastructure hardware who previously worked with Dama when she was general manager of Intel's Connectivity group before serving a two-year stint at Broadcom.
