So, here's what we can do:

 1) I can resend the series with this change in it (i.e., number of 
   domains weighting 3 times more than free memory);

 2) I can resend the series like in 1) _but_ while also converting the 
   domain counting in vcpu counting (I checked that and it's trivial);

 3) I can resend the series like in 1) and also send a separate patch 
   turning the domain counting in vcpu counting, and we can apply that 
   after it get some testing;

Which one you like better?

Regards,
Dario
