For those of you who want to hear Ian’s latest comments on Xen, etc – Doug Brown of www.dabcc.com has just posted a PodCast at http://www.dabcc.com/podcastdetail.aspx?id=75.
From VMBlog.com (http://vmblog.com/archive/2008/12/15/podcast-with-xen-open-source-virtualization-founder-and-citrix-vp-ian-pratt.aspx)
n episode 67, Douglas Brown interviews Ian Pratt, Vice President of Advanced Products for Citrix Systems, Inc.Â Â Ian is also the co-founder of XenSource, the company Citrix bought and turned into the XenServer solution, along with the head of development of the Xen open-source hypervisor project.Â Needless to say we were very excited to have Ian on the show.Â Â Ian and Douglas discuss Ian’s role at Citrix along with his views on everything from client side hypervisors to virtualization security, to the differences between the Xen hypervisor and Citrix’s XenServer hypervisor.Â Douglas and Ian also discuss the following subjects:
- Who is Ian Pratt
- Pro and Cons of Virtualization
- Client side Hypervisors
- Virtualization Security
- History of Xen Hypervisor
- Difference between Xen Hypervisor and Citrix XenServer
- A bit about the Xen.org Community
- Benefits of paravirtualization and enlightenment
- Memory Overcommitment
- Plus much more…
It’s been a year since Citrix bought XenSource, the company created by the founders of the Xen open-source hypervisor, and integrated the business into its lineup of products delivering applications to desktops.
As part of the process, Citrix made the XenServer virtualization software central to its strategy, and appointed XenSource staff to senior executive positions.
ZDNet UK sat down with one of those executives, Ian Pratt, Citrix’s vice president for special products, to find out how the integration is going and where Citrix is going with Xen-branded products.
I have just posted Ian Pratt’s slides from LinuxWorld at http://www.xen.org/files/IanPrattlinuxworld-xen-Aug2008.pdf. Feel free to take a look…
Pivot3 today announced a new solution for serverless computing based on open source Xen. You can learn more about their solution at http://www.pivot3.com/products/serverless-computing. Ian Pratt was quoted in their release:
â€œPivot3 has taken advantage of the openness and high performance of the Xen hypervisor to deliver a powerful new architecture for storage subsystems,â€ said Ian Pratt, chairman of xen.org. â€œXen virtualization is rapidly becoming embedded in all components of enterprise IT architectures, from servers, to storage and network appliances.â€
This solution was named a finalist for the â€œBest Virtualization Solutionâ€ category at the LinuxWorld Product Excellence Awards to be presented at the LinuxWorld Conference & ExpoÂ® in San Francisco on August 5, 2008.
Ian Pratt spoke at the USENIX Annual Technical Conference a few weeks back in Boston. Here are the slides from that presentation.
This is a talk in three parts. I’ll give a summary of the Xen story so far, looking at how Xen made the transition from research project to enterprise software and the many challenges along the way. Next, I’ll look at why virtualization is such a hot topic in IT and the failings of common operating systems that have led to this. I’ll then look at how Xen has evolved since the 2004 SOSP paper, seeing how paravirtualization and software/hardware co-design have helped reduce the overhead of virtualization.
