From Thiago Camargo Martins Cordeiro in Xen-Devel (http://markmail.org/thread/2t2cbfjkxz6awnzu):
I’m happy to announce everyone that is available a newer version of the Xen Live CD, the version 2.0.
It’s entirely based on latest version of the stable Debian, the recently released 5.0.
The Live CD Xen has several different examples, illustrating some situations and solutions. For example, two versions of Xen, 32 and 64 bits, 32 and 64 bits dom0, HVM machines, PVM machines, examples of PyGRUB, and more!
Visit the Wiki page http://wiki.xensource.com/xenwiki/LiveCD to download it today!
** Special thanks to Thiago for his great efforts in putting together a new LiveCD for the community. I believe that everyone will find this valuable!
My recent Podcast with Doug Brown of Dabcc.com Radio is live at http://dabcc.com/article.aspx?id=9968. I do my best to promote the community and the many ways that people can get involved beyond being a developer.
In the second posting on my explorations with Xen 3.3.1, I am going to highlight the steps I followed and problems I had when launching a simple pre-built DomU image.
Like my compiling Xen post – this is not for regular Xen users but for people thinking of trying out Xen on their own for the first time.
1) Pre-built DomU Image – I started with a very simple version of Linux to bring up, ttylinux. The file I used is at http://www.xen.org/files/ttylinux-i486-8.0.img.
2) Configuration File – I built the file ttylinux in the /etc/xen directory. The only issue I had was that my first version did not have the extra=’xencons=tty’ line so my DomU would start and then sit there with nothing happening execpt the cursor blinking. The additional line gave the console control of the DomU process so I could login, etc.
kernel = “/boot/…”
name = “ttylinux”
vif = [ ” ]
ip = “local ip”
disk = [‘file:/home/location…/ttylinux-i486-8.0.img, sda1,w’]
root = “/dev/sda1 r0″
extra = ‘xencons=tty’
3) Running DomU – In the /etc/xen directory I run: sudo xm create -c ttylinux which launches the ttylinux DomU in the same console window. In another console window, I run sudo xm list and am able to see the Dom0 and DomU running.
4) Stopping DomU – To stop the DomU, I run: sudo xm destoy ttylinux which immediately stops the DomU process. I then run sudo xm list to confirm.
For more details on the configuration paramters and their meaning, I recommend the Runinng Xen book, searching on http://xen.markmail.org or the Clarkson University Tutorials from USENIX training.
In my next posting, I will take a standard linux distribution and create a DomU version and launch on Xen. Stay tuned…
From Simon Crosby’s Citrix blog posting We’ve Open Sourced Our Optimized VHD Support:
Today Dutch Meyer of UBC, and Jake Wires of the Citrix XenServer storage team in Vancouver submitted our implementation of the Microsoft VHD virtual hard disk format to the Xen community for inclusion in the open source code base. So, if you want to write applications that read/write and process VMs in VHDs, you now have everything you need. The software is licensed under the BSD license.

The Virtualisation and cloud track of Open Source India Tech Days (www.osidays.com) is scheduled for March 13, 2009 (at Chennai). We’re
planning panel discussions where we’d like Xen to participate, besides looking for a presentation on Xen as to what are the latest features, et al.
If you are interested in supporting the Xen.org community at this event, please contact me and I will put you in touch with the appropriate contacts.
