Xen on ARM: Status and Performance - Stefano Stabellini, Citrix

Sign up or log in to save this to your schedule and see who's attending!

As the first ARM servers and microservers hit the market, Xen on ARM is becoming more mature, stable and reaching feature parity with x86. This talk will present the current status of the project, will describe the latest improvements, the gaps that still need to be filled and the roadmap going forward. ARMv8 silicon is now available for purchase: we can measure how well Xen on ARM 64-bit is performing on real hardware and compare the performance figures with other hypervisors. The presentation will show these results, it will measure the overhead introduced by Xen on ARM and will compare it with the overhead introduced by Xen and KVM on x86. The talk will explain the reasons behind performance shortfalls and present ideas on how to address them in the future. The performance results will be used to determine when it makes sense to use Xen on ARM and what are the best use cases for it.
