Oracle 'Losing Patience' with XenSource, VMware

HiTech writes "eWeek has an article looking at Oracle's frustration with both XenSource and VMware over their reluctance to work together. The goal is to develop a single interface for virtualization solutions in the Linux kernel. Oracle's comments follow those by Linux kernel maintainer Greg Kroah-Hartman at Oscon last week that XenSource and VMware were butting heads instead of working together to come up with a joint solution. Brian Byun, VMware's vice president of products and alliances, admits the company had been approached by a neutral third party for offline mediation to establish how best to make this happen. But Simon Crosby, the CTO for XenSource, rules out any mediation, saying he believes the two companies are committed to solving the real technical issues."

Not necessarily. Linux seems to be about new ideas and reinventing the wheel. Why are there so many file systems for example? There are valid reasons to have different interfaces. Perhaps different performance characteristics or access to system devices might be an issue. It takes serious planning and commitment not to change the api. The linux changelog suggests this is a big problem for some. The argument that its better doesn't always cut it.. why do you think windows is bloated?

As long as they both write their code using vim, I don't care which one I use.

Are you kidding?

Seriously people, this is computer software we're talking about, not Israel and Hezbollah.

You're kidding, right? This is computer software, the battleground of OCPD personalities, where one aspect is taken out of context and used to judge something into "perfect" and "complete evil" categories, with no middle ground. And then proceed to try to raise a crusade to death against the complete evil ones. It's the place where vi vs emacs, KDE vs Gnome, Java vs C++, Intel vs AMD, goto vs for/while loops, and of course OSS vs anything else isn't just worth a debate, but become religious wars and things to fight to death for or against.

I bet that when your stereotypical ultra-militant extremist-Islamist organization's meetings go out of hands, someone could interject "stop it guys, you're starting to sound like on the OpenBSD mailing lists." And, assuming they've even heard of OpenBSD, the previously screaming and fist-shaking speakers would blush and start staring at their own shoes in silence.

In fact, if the Hesbolah vs Israel _were_ like the software holy wars, God help us, because there's be no possibility of peace ever. I could just see a peace talks turning into "ok, you may have aggreed to free Palestine, pay reparations, change your language to Arabic, convert to Islamic faith, recognize the Ayatolah's authority and everything... but... YOU RUN YOUR SERVERS ON WINDOWS! DIE INFIDEL!!!"

Personal opinions

Disclaimer: VMware employee, personal opinion.

VMware went to OLS and presented a paper demonstrating a VMI interface that runs either Xen or VMware at the same speed as the Xen interface. Xen has never tried to run on a VMware hypervisor, but XenSource went and signed a deal to run on the (future) Windows hypervisor. My opinion is that Xen is a bunch of hypocrites: they complain about how VMware isn't open, then go sign a deal with the least open company of all. Of course, I'm biased.

Xen wants VMware to adopt the Xen hypervisor interface. This is impossible. The Xen interface is too tightly coupled to the Xen hypervisor; it's missing pieces that are necessary to run the VMware hypervisor at reasonable performance. VMware doesn't really care which interface actually proliferates (as in, there will be a layer of interface glue regardless), so long as the interface is good enough. Xen's interface is not good enough. As of two weeks ago, Xen and VMI were the only two interfaces out there.

Greg K-H's gripe with VMware is that the kernel module isn't open source. Yes and no (I don't want to argue - the code is open but not GPLed), the point is that he's spending more time complaining about Xen and VMware than it would take to actually mediate the problem. (Which, thankfully, someone else is doing instead, with paravirt_ops).

Finally: I saw more pot-shots about being unable to benchmark VMware in the original article. That changed several months ago, benchmarks are now allowed by EULA. Certain companies ought to stop spreading FUD...
