Re: [Xen-ia64-devel] Time for hybrid virtualization?

[tgingold@xxxxxxx]

Hi,

here are my random thoughts:

* First, I am all for supporting dom0 VTi (as well as dom0 PV).  This should
  be an intermediate step.  Intel did that in the past, although I am not
  sure it was fully virtualized (what about GFW ?)

* Building a dom0 vti means porting backend, balloon and all other drivers to
  Vti.

* What about performance on Montecito ?  If Montecito Vti is ~55% of Montvale,
  I'd prefer to keep PV.

* Do we want to abandon PV domains ?  Siemens people may still use them.  I am
  not sure there is a large gain in abandoning linux dom0 PV but keeping
  linux domU PV.

Tristan.
