[vbox-dev] Enable memory ballooning

[Jinchun Kim]

Hi, All.

I found that there is a source code which is responsible to inflate or
deflate memory balloon in each VM.
For example, VBoxGuest.cpp has *vboxGuestBalloonInflate **and** **
vboxGuestBalloonDeflate** to control the ballon size.*
*However, when I run a VM and check the log file, it seems like ballooning
is not enabled at all.*
*The VBox.log says*
*
*
*00:00:36.674125 /GMM/VM/cBalloonedPages                131072 pages*
*........*
*00:00:36.674148 /GMM/VM/cReqActuallyBalloonedPages        0 pages**
*
*00:00:36.674154 /GMM/VM/cReqBalloonedPages                   0 pages**
*
........
*00:00:36.674209 /GMM/VM/fBallooningEnabled     false*
*
*
*Of course, I have installed Guest addition and run vbox on 64-bit host
machine.*
I already asked this question in virtualbox forum but didn't get a clear
answer...
Does anyone have an idea how to enable memory ballooning in vbox?


Thanks.
