Sessions at FOSDEM 2012 about Virtualization and xen with video

• The Wild West of UNIX I/O, and how we might tame it

  by Anil Madhavapeddy

  This talk will firstly discuss the impossibility of using current APIs efficiently (via benchmarks on a diverse set of hardware (from many-core AMDs to the experimental Intel SCC). Finally, I will describe our work on introducing a hierarchical name system and extended socket API that adds support for automatic transport selection and reconfigurable sockets. This permits many NUMA-related optimisations on single hosts, for VMs to switch to shared memory communication if on the same physical host, and for seamless network-wide protocol upgrades to multi path TCP or TCPcrypt.
