Virtualization technology has grown beyond server systems to include desktops, notebooks, and even mobile devices. The rich settings in which virtualized systems are used range from cloud computing infrastructures requiring access to high-end I/O devices like GPUs and networks to the many devices present in embedded and mobile systems. Consequent requirements imposed on I/O include the need for extreme-scale performance in high performance or low latency systems; fairness in device sharing in cloud and server systems, which includes online methods for understanding the I/O behavior of applications; trusted I/O both for cloud and for mobile systems; and low overhead and reliable device access in the mobile or embedded domains.

While I/O systems have a long history of using abstraction to shield applications from the intricacies of devices and storage systems, this workshop's focus is on the interplay of I/O with virtualization and cloud technologies. Our goal is to provide a forum to discuss the impact and challenges of I/O virtualization along multiple dimensions, including: the application domains in which virtualized solutions are used and the subsystems involved; platform or hardware support for I/O virtualization; the virtual machine monitor; the guest operating system; the processor, GPU, memory, and I/O subsystems. Also of interest are higher-level virtualization solutions, such as those concerning API virtualization, new virtual I/O APIs like those used for cloud storage, and innovative approaches to device virtualization in cloud computing and in the mobile domain. We welcome papers that describe new challenges and solutions in I/O virtualization and papers that describe novel approaches to solving known problems. The final program will consist of both reviewed submissions and invited talks. The invited talks will focus on open problems in I/O virtualization and will be accessible to a broad audience.


Topics of interest include but are not limited to:

  • Hardware support for I/O virtualization
  • Novel I/O device architectures for virtualization
  • New software approaches to I/O virtualization
  • Hardware and software methods for I/O device emulation
  • Para-virtualized I/O device driver design for virtualization
  • Virtual machine monitors' support for I/O
  • Security and trust considerations for virtualized I/O, including hardware support
  • Energy-efficient I/O virtualization
  • Virtualized I/O in the cloud: API virtualization, challenges of large-scale I/O (performance, availability)
  • Virtualization mechanisms for datacenter networking
  • I/O monitoring and black box methods or system support for such functions

Submission Guidelines

Please submit an extended abstract in PDF format through the workshop submission Web form. The extended abstract should be no more than 4 double-column pages using 10-point type on 12-point leading ("single-spaced"). Figures and references are not included in this 4-page limit. The committee also encourages the submission of short papers to update WIOV '11 attendees on new efforts or approaches. Please label such submissions accordingly.

All accepted papers will be available online to registered attendees before the workshop. If your paper should not be published prior to the event, please notify The papers will be available online to everyone beginning on the day of the workshop, June 14, 2011.

Simultaneous submission of the same work to multiple venues, submission of previously published work, or plagiarism constitutes dishonesty or fraud. USENIX, like other scientific and technical conferences and journals, prohibits these practices and may take action against authors who have committed them. See the USENIX Conference Submissions Policy for details. Questions? Contact your program co-chairs,, or the USENIX office,

Papers accompanied by nondisclosure agreement forms will not be considered. Accepted submissions will be treated as confidential prior to publication on the USENIX WIOV '11 Web site; rejected submissions will be permanently treated as confidential.
