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, Andreas Kind regards / Mit freundlichen Grüßen ****************************************************************** Andreas Löffler | VirtualBox Engineering Principal Software Engineer | Oracle Virtualization ORACLE Deutschland B.V. & Co.
