[ovirt-users] change Memory Ballooning setting

[Nelson Lameiras]

Hello oVirt gurus, 

When activating/deactivating memory balloning on VM, this will change /usr/libexec/qemu-kvm command line on host on vm startup (you can see it using "ps aux"). 
So I understand a vm reboot is needed to take this change into account. 

But when activating/deactivating memory balloning on Cluster (plus MoM Sync on host) I do not really understand what happens "under the hood" 

- Is there a mechanism on host which controls "memory balloning" globally? 
- Is it able to change it's behaviour "on the fly" with "MoM Sync" ? 

If you have any information, it would be greatly appreciated 

cordialement, regards,
