DESCRIPTION:Edouard Bugnion\, Stanford University\nAbstract\nVirtualizatio
 n has gone through a full ``popularity cycle''. Originally conceived in th
 e mainframe era\, virtual machines provided an efficient\, isolated\, and 
 compatible duplicate of the hardware of the underlying machine.  Virtual 
 machines quickly lost popularity with the increased sophistication of oper
 ating systems\, and subsequent processor architectures were designed witho
 ut consideration for virtualization.\n\nIn this talk\, I propose to use vi
 rtual machines to address limitations of commodity operating systems on mo
 dern architectures\, even in the absence of architectural support for virt
 ualization in the hardware.  The primary technical contributions of the w
 ork were developed as part of two systems\, each built for platforms with 
 limited architectural support for virtualization. First\, Disco ran commod
 ity operating systems on scalable MIPS multiprocessors. Disco enabled virt
 ual machines to form a virtual cluster that could transparently share the 
 resources of the underlying multiprocessor. Second\, VMware Workstation is
  a successful commercial product that allows multiple\, unmodified operati
 ng systems to run concurrently on the same x86 system\, allowing users to 
 decouple their guest operating systems from the underlying hardware.  VMw
 are Workstation was the first 32-bit virtual machine monitor for the x86 a
 rchitecture\, and demonstrated that the x86 architecture was indeed virtua
 lizable\, despite a lack of architectural support.\n\nToday\, and in part 
 because of the impact of Disco and VMware\, virtual machines once again pl
 ay a foundational role in Information Technology\, and current-generation 
 hardware provides architectural support for virtualization\, similar to wh
 at already existed decades ago on mainframes.\n\nBiography\nEdouard Bugnio
 n started his Ph.D. at Stanford in 1994\, and is expecting to finish it th
 is month.  In the meantime\, he co-founded two successful companies: VMwa
 re and Nuova Systems (acquired by Cisco).   At VMware from 1998 until 20
 05\, he served multiple roles including CTO.  At Nuova/Cisco from 2005 un
 til 2011\, he built the core software team and became the VP/CTO of Cisco
 ’s Server\, Access\, and Virtualization Technology Group\, a group that 
 brought to market Cisco’s Unified Computing System platform for virtuali
 zed datacenters.  \n\nHis research interests include computer systems\, 
 datacenter and cloud networking\, as well as technology entrepreneurship.
   For their work\, Bugnion and his colleagues have received the ACM Softw
 are System Award (for VMware) and the ACM SIGOPS Hall of Fame Award (for D
 isco).  Edouard was raised in Neuchatel\, Geneva\, and graduated from ETH
 Z.\n
