Hi all,
I'm new to this forum and kinda have a noob question on memory ballooning. Now i know that memory ballooning is one of ESX RAM reclaiming techniques and it balloons a guest OS RAM and swaps it to the guest OS swap file the host created, is that right?
Say I have a VM with 2GB of RAM allocated, ballooning occurs and balloons to 1GB. I guess my question is, this 1GB thats ballooned, is this reserved for the VM (1GB the host can't touch) or this 1GB moved off the VM? Im just trying to understand how ballooning works and comparing that with the information under the "Resource Allocation" tab of a VM in Vsphere client.
Hope this makes sense.
