Xen Summit Logo

XenSummit has been a tremendous success this year. Thank you to all the speakers for contributing and to all the attendees for making XenSummit an interactive and fun conference with lots of discussions. You can find presentations on slideshare and videos on vimeo. We will also embedded both in the agenda. The slides are also available for download as zip file.

Xen on ARM Cortex A15

During the last few months of 2011 the Xen Community started an effort to port Xen to ARMv7 with virtualization extensions, using the Cortex A15 processor as reference platform.The new Xen port is exploiting this set of hardware capabilities to run guest VMs in the most efficient way possible while keeping the ARM specific changes to the hypervisor and the Linux kernel to a minimum.

Developing the new port we took the chance to remove legacy concepts like PV or HVM guests and only support a single kind of guests that is comparable to "PV on HVM" in the Xen X86 world.

This talk will explain the reason behind this and other design choices that we made during the early development process and it will go through the main technical challenges that we had to solve in order to accomplish our goal.
Notable examples are the way Linux guests issue hypercalls and receive event channels notifications from Xen.
