[CentOS] Load-Balancing Virtualized Guests

Hi everyone:

According to "Automated failover and recovery of virtualized guests in
Advanced Platform", one can easily migrate virtualized guests around
different hosts. However, is it currently possible for CentOS 5 with
Virtualization&Clustering Suite to migrate guests dynamically
according to loads on different hosts?

Thanks,
