I'm not sure why, but there's a ton of speculation in the Blogosphere today about the so-called XenClient from Citrix.. (Apart from the fact that there is nothing called XenClient - it's Project Independence).

  1. The writer is misinformed. If you want to see a video demo of one particular use case, see here.
  2. It would be foolish to assume anything about the product that Citrix will deliver to market.  For starters, we're still evaluating key opportunities and putting pieces together to deliver on specific use case scenarios so any presumed intelligence is almost certainly wrong.
  3. If you want to know what we're actually doing, show up at Synergy, and see for yourself.  There will be more relevant tech and more relevant product to your world than ever before at this event, and a whole lot less marketing BS.  Moreover Geek Speak Live offers a no-holds-barred opportunity for you to challenge presumed experts (including me) on every aspect of our strategy.

Meanwhile, consider this to be nothing more than nonsense anything else you read on the web without thinking.

    Considering the obvious enthusiasm for Project Independence you have to expect just a little speculation here and there. After all...

    I don't think the original author, Gabe(http://www.gabesvirtualworld.com/?p=396), was assuming anything. Gabe got his info from Joel Stocker(http://community.citrix.com/blogs/citrite/joels). Maybe Joel was misinformed, but with Joel's job title being " Senior Technical Product Manager of the Virtualization and Management Division" I would also assume he knows what he's talking about.

    Not really sure why you would want to make other people(the bloggers) look bad though, but that seems to be a common theme in your posts.

    Dear Mr Crosby,

    As author of the article "Citrix Xenbased client hypervisor a very early preview" http://www.gabesvirtualworld.com/?p=396 I must admit I was surprised by your reaction in which you write that my article is nonsense. Well, you did strike the nonsense part, but something must have gone wrong in your editor because it still shows.

    The info I presented in my article is from a conversation I had with Joel Stocker and by the look of his business card ("Senior Technical Product Manager of the Virtualization and Management Division", I thought he was in the loop and knew the ins and outs about the client hypervisor he demo-ed. Unfortunately from your post it seems he isn't, because, to you my article is nonsense. I'm pretty sure that I have a correct representation of the conversation I have had with him, since I wrote down quit some notes during the conversation and on some points repeated to him what I have written down. I also discussed with him my opinions on what I had seen and on some points he agreed.

    So I'm very curious to know what went wrong in the conversation and of course I would also like to know on which points my article is incorrect.

    With kind regards
    Gabrie van Zanten

      Gabe

       Your article was well intentioned, however the product is not on the market, and therefore asserting limitations in architecture or any such thing based on a single use case that has been presented by the company (Joel etc were absolutely correct in what they said, but the technology is not limited to the specifics of the use case that we have been articulating) is wrong.  Leaping to a conclusion related to security etc prior to anything being available to kick around or examine is pointless.  We will welcome your feedback and examination when the product goes to market.  Note that the Independence hypervisor is not limited only to the use cases that Citrix will exploit; it is generally useful for any client side virtualization use case.

    I believe from the way is was presented, (and this is from the preview not the blog. I know the original writer and was at VMworld with him when it was shown him). The solution is much more akin to the "view offine client" coupled with a Linux backend. It sounds to me like somebody just down loaded the VMware linux view client and messed around a bit (laymans comment - I am not a developer). I appreciate that this is Alpha code and will be subject to significant change, but if Citrix do not want people to comment on their products they should be more circumspect in what they release and the time they release them.  Joel is one of your "Senior Technical Product Managers" if he does not understand the product and the message it does not bode well in my humble opinion.

    So I repeat the way the architecture was described is more akin to a hosted environment, not a bare metal hypervisor.

    oh and Simon just so you know My name is Tom Howarth and I would love to have a conversation about virtualisation with you.

     Regards

    I agree with all the above comments. My perspective on project independence is _very_ different from Gabe's, because I was fortunate enough to have a lengthy private chat with Ian Pratt about it some weeks ago, rather than some "senior technical marketing" guy.

    If "senior technical marketing" people employed by Citrix are ill informed with regards to Citrix technology, then perhaps they should just shut the fuck up instead of trying to pull off lame publicity stunts like announcing and demo'ing new Citrix technology (as in new to the public, I know how long this has been under wraps) at a VMware conference. This marketing guy was clearly not well informed on the intricacies of the product, thus unable to accuratley comment on Gabe's insightful observations. Had Gabe been talking to Ian Pratt, that post would have been completely different.

    Exactly as Gabe said, for you to ridicule his post is to ridicule your own "senior" staff.

      OK, let's not get personal here.

      There is a difference between what is presented by those who are given a specific market facing viewpoint of what can be done, versus the core capabilities of the technology.

      Gabe was absolutely correct in what he presented, for the use case he presented. However, to infer that the technology is limited solely to that use case would be completely incorrect.  So, Gabe is not at fault, he's in fact articulating one of the key use cases of the technology.  The fault is on the part of those who do not know about the internals of the product (nobody's fault - it hasn't been publicised) but who insist on leaping to conclusions about vulnerabilities or limitations.

    Dear Simon Crosby,

    Why do you always get involved in a "web fights" ?

    Given Citrix's impressive roadmap regarding virtualization I am pretty sure you have better things to do with your time than commenting every blog post you disagree with.

    But when you do please think twice, we are not all competitors, haters, blind vmware fanboys and so on ...

    True, sometimes we might be misinformed, then please try your best to correct us without being arrogant.

    It is good that you stand up for your products, we all appreciate that but this is starting to be counter-productive from my opinion.

    Thanks in advance

    Asked but not answered on a previous blog post of Simons.  Reposted here, and cleaning up:

    Simon,

    Can I use the "free" Citrix offering to host VMs that I can then in turn rent or lease?  Or is reselling or hosting for profit, something that can only be done with the licensed, supported version?

    I've tried getting to the EULA via the web page, but can't seem to find it without signing in.  Either an answer or a link would be great.

    ESX 3i (and ESX in general actually) does not allow for reselling of VMs as a service model without a legal change to the EULA. 

    Does Citrix?   

    Thanks!

    Interesting that you say "Apart from the fact that there is nothing called XenClient - it's Project Independence"... clearly something has changed in the last couple of months as the Project Independence web page on the Citrix site now has a header which says "XenClient" (mind you, it also has a link to download a trial... which then takes me to the XenDesktop page...)

    Looks like the whole message is a little confused. Shame, because, based on the video on the Citris site, this looks great and it seems to provide what Microsoft is so far failing to: a type 1 hypervisor that's designed for the desktop.
