Taming Heterogeneous NIC Capabilities for I/O Virtualization

Jose Renato Santos, Yoshio Turner, Jayaram Mudigonda
2008 USENIX Symposium on Operating Systems Design and Implementation  
The recent emergence of network interface cards (NICs) with diverse hardware features for I/O virtualization poses an important challenge for virtual machine environments, particularly in the area of system  ...  In addition, we propose new mechanisms for intra-node guest-to-guest networking that leverage NIC hardware switching support, and we present a unified system architecture for network I/O virtualization  ...  Acknowledgement We would like to thank Ian Pratt, Steven Smith and Keir Fraser for helpful discussions during the design of Xen Netchannel2 which inspired some of the ideas described in this paper.  ...
