[Xen-users] paravirt_ops DomU, does it mean performance?

["Emre Erenoglu" <erenoglu@xxxxxxxxx>]

Hi,

I was wondering if using a paravirt_ops enabled kernel (say 2.6.23) as a Paravirtual DomU would mean higher performance out of the box, or if we still need to compile some xen specific device drivers for network and block devices.

Similarly, if HVM domains can run at the same performance as PV domains just by using PV drivers for network and block, why are we bothering ourselves with PV?  Why don't we -always- use HVM DomU's with PV drivers?

Thanks for views on this,

Br,
