Hi everyone,



I'm getting a master's= degree on virtualization and I'm trying to trace the interference of hyper= visor scheduler on quality of service of network intensive domains.

I'm pretty sure xentrace is the way to extract most of my performance m= etrics.
However, I'm struggling on finding some good documentation about= xentrace usage.


Basically, what I want to know is if I can extr= act this kind of information from xentrace and how can I do this.

> vCPU usage
> I/O count per domain (number of network I/O reque= sts received by a target domU over dom0. Can be memory page flip between do= m0 and domU)
> priority states for a given vCPU per period of time (n= umber of over, under, boost state experienced by a vCPU).



Is it possible to get this information? How can I do this?


Any= additional information can help me.


I appreciate your attention=
