In OLS 2005, we described the work that we have been doing in VMware with respect a common interface for paravirtualization of Linux. We shared the general vision in Rik's virtualization BoF. This note is an update on our further work on the Virtual Machine Interface, VMI. The patches provided have been tested on 2.6.16-rc6. We are currently recollecting performance information for the new
