processor priority for domains?

processor priority for domains?

[Ricardo Staudt]

I've been playing with Xen for a while now and I found nothing related 
to this topic yet:

Is there a way to set the processing priority to a certain Domain over 
the others? Maybe setting a percentage of max processor usage per domain?

I realize you can set the amount of ram memory per domain, but I found 
nothing related to the processor.

If not in Xen, is there a way to set this limitation on each running 
Linux OS? (a Linux configuration file? kernel?)

Thanks in advance!

You can set parameters on the schedulers.  There's a function 
xc_domain_setcpuweight() that provides an interface to this.  
Beforewarned, it only works properly when using the BVT schedulerly.
