For instance if your host has 4GB of memory, you can assign each VM 3GB. b) Run memory intensive workload (memhog), that touches ~75% of memory in one VM. You should see target != 0. You can try above experiment in different config, for eg. assigning less memory where you plan to run intensive workload, so as to see ballooning taking place.. > - Is there something obvious I'm missing? > > thanks, > > John > Shailesh Jain ------------------------------------------------------------------------------ Come build with us!
