[vbox-dev] How to test memory ballloon ?

Hello Hans,

please have a look at the manual, section 4.9.1 "Memory ballooning" and
commands like

VBoxManage controlvm "VM name" guestmemoryballoon <n>

VBoxManage modifyvm "VM name" --guestmemoryballoon <n>

There is also a frontend called VBoxBalloonCtrl in our tree which can be
used to control those values. This also could act as an example about
how to use ballooning / the API.

Hope this helps,

Kind regards / Mit freundlichen Grüßen
