Hi all,

I am trying to implement Page Fusion for x64 Linux guests. I understand that this will require changes to the Guest Additions. Specifically, in the VBoxServicePageSharing.cpp code. I have made some changes here and I am trying to call VbglR3RegisterSharedModule function with information about Linux guest modules.

1. I am unable to put a trace in the R3 code, the code for the VMM / hypervisor. I am unable to see the LogFlow() messages. Can you help me enable it ?

2. Is the code that implements page-fusing / sharing in the VMM specific to windows ?

Thanks in advance !

1. Did you take a look at logging information here: https://www.virtualbox.org/wiki/VBoxLogging (see Ring-0 logging)?

2. From a quick glance, the guest additions part of the code is specific to Windows, on the host side it is platform agnostic (not enabled for 64-bit darwin hosts though). The guest addition side has some compile-time defines that only register the service hooks for Windows (VBoxService.cpp).

Ram.
