Here is the bit from my book about using Ionice:


more recent but poorly written notes here:

The problem is that all these changes go away upon reboot of the guest;  
So far, I only do this when there is a problem, and I watch it, so that
aspect is good.  I can tell the user to deal with it and reboot
when they are done to remove the limit.

One of these days I'll write a script to do this from the xm config 
file or otherwise have the limiting happen on boot, but I haven't gotten
that far.
