I'm trying to understand why I'm seeing much ballooning on a VM: frequently ESX reclaims up to 7 GB from a VM configured with 12 GB and it is a burdensome process.
I think I have no much overcommit rate on the host and not much memory pressure but I'm not sure.
Some help to indagate?
Move some VM off the host, to have approx 20GB granted. And then start to move machines one by one to the host while watching memory stats.
