Hi every one:
 
I am a new guy here, and I have a idea for xen automaticaly live migration. I have two computers installed domain0 and some xen virtual machines, now it can do live migration manually, and I want to develop a tool to do migration automatically based on the cpu occupancy. This tool includes one major daemon, one module for collect the information of two computers,another module for creating a rule for determine whether the migration is taken place, and a configuration file.
 
The problem is what the rule is reasonable. I have a raw idea:when the cpu occupance of  computer A is more than 50% or 60%, and the other one B is 20% less than A, the migration occurs and takes one or more virtul machine from A to B, to get a balance cpu occupance between these two computers.
 
welcom any discussion or suggestion!
 
Thanks!
