Event Report: Xen Project Developer Summit 2015

Posted by on in Events

This year's Xen Project Developer Summit is over! We had two days packed with highly technical sessions that were attended by 120 delegates. Our sessions have - as always - been very interactive with lots of discussions during and after the talks. Of course we did also have lots of time for in-corridor conversations during breaks, which most of us look forward to every year. XPDS15
