I would like to give one of my KVM guests a lower priority when it comes to CPU resources than my other KVM guests.
(yeah, you probably guessed it. It's my BOINCing KVM guest...)
I use virt-manager 0.7.0-4 to manage my KVM guests, but it doesn't seem to have any option for this kind of resource management.
Currently I manually renice the kvm-process of the BOINCing KVM-guest process after starting it, but I would prefer a smoother/nicer solution...
