Couldn't make it to this year's Xen Project User Summit in New York City?  No problem!  Most of the videos are now available for viewing at XenProject.org.  These aren't highlight reels or a handful of talks from a few selected people; these are the meat-and-potatos talks from our event.  Most sessions are available right now; the final few should be posted in the next few days.

Take a look at some of the great talks already available...

Open@Citrix sponsored the 3rd annual poker party at OSCON on Tuesday, July 22nd at OSCON. Poker tables were hosted by various open source projects. Thank you to ManageIQ, Fedora, Ceph, Bitnami, OpenShift, Apache CloudStack, Xen Project, OpenDaylight, SaltStack, Chef, Ansible, Atomic, oVirt, OrangeFS, CentOS and Apache Libcloud. It was a night filled with live music, beer, cocktails, hors d'oeuvres and prizes. Congrats to the lucky top 3 chip winners who took home Samsung Chromebooks 2!

Open Cloud Lounge

The Open Cloud Lounge was a comfy spot for OSCON attendees to hangout at. There were OpenDaylight, Apache CloudStack and Xen Project beanbags. Community members from the Xen Project and Apache CloudStack project handed out swag and cupcakes.

How fast is Xen on ARM?

Posted by on in Cloud News

This is a repost of Stefano Stabellini's blog post on blog.xenproject.org

With Xen on ARM getting out of the early preview phase and becoming more mature, it is time to run a few benchmarks to check that the design choices paid out, the architecture is sound and the code base is solid. It is time to find out how much is the overhead introduced by Xen on ARM and how it compares with Xen and other hypervisors on x86.

I measured the overhead by running the same benchmark on a virtual machine on Xen on ARM and on native Linux on the same hardware. It takes a bit longer to complete the benchmark inside a VM, but how much longer? The answer to this question is the virtualization overhead.

Setup

I chose AppliedMicro X-Gene as the ARM platform to run the benchmarks on: it is an ARMv8 64-bit SoC with an 8 cores cpu and 16GB of RAM. I had Dom0 running with 8 vcpus and 1GB of RAM, the virtual machine that ran the tests had 2GB of RAM and 8 vcpus. To make sure that the results are comparable I restricted the amount of memory available to the native Linux run, so that Linux had all the 8 physical cores at its disposal but only 2GB of RAM.

For the x86 tests, I used a Dell server with an Intel Xeon x5650, that is a 6 cores HyperThreading cpu. HyperThreading was disabled during the tests for better performances. Similarly to the ARM tests, I had Dom0 running with 6 vcpus and 1GB of RAM and the virtual machine running with 2GB of RAM and 6 vcpus. The native Linux run had 6 physical cores and 2GB of RAM. For the KVM tests I booted the host with 3GB of RAM, then assigned 2GB of RAM to the KVM virtual machine.

If you use the Xen Project Hypervisor, you have a rare opportunity to share what you've learned with your peers.  On September 15, 2014 in New York City, we will be holding our second annual Xen Project User Summit -- and we want you to join us there!

We are looking for talk proposals which will be of interest to other Xen Project users.  Subjects of interest include (but are not limited to):

  • How you use our project’s software in your datacenter or lab
  • How you integrate the Xen Project hypervisor in your solution or cloud
  • How you control the software with custom scripts or utilities
  • Why you chose Xen Project software instead of some other hypervisor
  • How much you time or money you saved by using our software
  • Where you’d like to see our project go in the future

Also, we’d welcome talks about:

  • Features of recent releases and how you use them
  • New projects building on Xen Project software which could open new avenues for end users (like the work around GPU virtualization, cloud operating systems like MirageOS, and additional architectures like ARM)
  • Instructive HowTo sessions to educate attendees about implementing particular capabilities within the software
  • The use of related products and projects (like XenServer, Xen Orchestra, CloudStack, etc.) to make our software even more powerful in the datacenter
