"An Overview of Resource Virtualization Techniques for Grid Computing"

This talk will overview techniques that support machine virtualization
and discuss the application of these techniques to Grid computing. 
Resource virtualization has drawn much renewed attention in recent years
with the advent of successful commercial and open-source virtual machines
for commodity hardware, such as those developed by VMware and XenSource.
The central concept of resource virtualization is the introduction of an
indirection layer below the execution environment seen by applications
and operating systems. Such indirection layer provides a basis for
achieving flexible, secure sharing of resources. The application of
virtualization to facilitate sharing is particularly appealing in "Grid"
computing environments, where resources are heterogeneous and distributed
across multiple network administration domains. This talk will also discuss
cross-cutting issues with respect to networking: virtualized distributed
systems for Grid computing require high-speed networking for the
instantiation and migration of VMs, and it is desirable to support
bi-directional TCP/IP connectivity among VMs hosted by multiple domains
and subject to independently managed firewalls.
