[Xen-users] How can PV be slower than PVHVM?

[Steffen Einsle <einsle@xxxxxxxxxx>]

Hi there,

after reading the PV vs PVHVM performance comparison at

https://xen-orchestra.com/blog/pv-vs-pvhvm-on-next-xenserver/

but I still cannot accept how a fully emulated system can even come 
close to the performance of a PV-only system. Every translation layer 
must add some overhead - right? So a true PV system without translation 
layer should (imho) be at the top of the performance list?
Or does the mentioned comparison apply only to debian on xen-orchestra?

My system is a barebone gentoo xen 4.10 Dom0 and multiple gentoo PV 
DomUs in PV mode - and now I'm confused...
