Abstract

IO performance in virtualized environment has always been a challenge owing to “in-direct” access to the hardware. This has been addressed using “pass-thru” techniques to directly access the hardware; however this does not allow migration of tasks. This presentation introduces a virtual interface technique that is used to route IO via this interface before the migration is initiated. This brings the IO performance in virtualized environment very close to the native driver performance along with support for all key features of virtualization. The presentation goes on to explain how this is achieved using a 10Gbe adapter in a Xen environment.
