Hi, looking at the 2004-xen-ols-pdf papers's xen 2.0 Architecture fig vs. the 1.2 fig, what is the differences between the device drivers? It seems like the drivers for 1.2 is ported to function in the paravirtual environment, but what is the deal with the 2.0 Front-end and Vanilla device drivers?

Fig 2.0 also has three red arrows, one from the 2.4 kernel to the HW layer and two from the domain 0. What does
this mean in contrast to fig. 1.2 ?

cheers,
Rune J.Andresen
