[PATCH] OSX VBoxGuest / VBoxService

[Toitoine]

Hello,

I've started to compile guest addition for OSX target.
For the moment, I've targeted the VBoxGuest driver only (Host-Guest Communication Manager).

For progress go to latest post.

Thanks for your interest in such effort !

VirtualBox supports Mac OS X guests since "Version 3.2.0 (2010-05-18)", from a year ago, and having Guest Additions would be great !

Good Luck !

You should discuss it with FreeBSD Guest Additions developers. (They did some coding independently from Oracle)

Hello,

I've got a working VBoxGuest driver, VBoxService is communicating with it and can be installed as a launchd service.

Complied with 10.7 sdk, tested on 10.6 VM.

[Technologov]

good start !

Now - the real stuff needs to be done:
-Mouse integration
-Video: Dynamic Resolution Resizing
-Time sync.
-Shared Folders

(community did much of that for Haiku and FreeBSD guest OSes)

[Toitoine]

I don't agree with you

Time sync is within VBoxService, so it already works !
VBoxGuest is the foundation for other drivers, so real stuff has already begin...

FreeBSD is not Darwin, the only useful code in common was in VBoxGuestCommonR3 lib used for VBoxService and VBoxControl. On the driver part, the work has to be done from scratch.

[Technologov]

Thanks for putting effort in this project !

It definitely looks interesting.
Today, biggest problem of OS X _guests_ is that they are simply too slow on VirtualBox (due to lack of 2D and 3D acceleration), but your effort will hopefully make OS X guests _useful_. (instead of just _runnable_)

For example:
Currently running OS X on VBox -
Scrolling a web page in Safari takes ages... (several seconds to scroll one page down). Same for minimizing application window, which becomes a multi-second endeavor, which takes 0.2 seconds on a real Mac.
Due to "Core Image" and other fancy stuff

Hi, could you post the actual code/patches somewhere? (Currently in this thread I only see a very small patch to one Makefile - which definitely doesn't look like enough to get anything actual working)

[Toitoine]

Hi,

I don't understand why you only see a makefile in the diff
This is the list of modified files/directories:

Compiled on 10.6 and 10.7 with respective SDK.
To apply the patch (in the source root) patch -p0 -i patch3.diff

To have a working time sync with VBoxService use the option --timesync-set-threshold 100

Oh sorry about that I should have looked closer. Wasn't on my normal machine and it looks like the machine in question had a broken .diff viewer that only showed one file for some reason. Looks much more reasonable now
Have you considered maybe setting up a gitorious copy of the repo or something like that for the purposes of this work? It might make it a bit easier for others to contribute and/or test it out.

No I've not think about this. For the moment I don't know if there are people interested for that. I've no knowledge on how to synchronize two VCS bases together.
As you can see, there are plenty few modifications in existing code and makefiles as VBoxGuest is in the common part of Additions. Other (unimplemented) drivers (framebuffer, sharefolder...) should be much more independent and located in a separated darwin subfolder. Best would be to have VBoxGuest patch incorporated by Oracle in the OSE svn...

With my apologies because as an end-user I won't be of any help for you here, this is just to say there are people very interested by your work on this topic!

Thank you for publishing your next steps, and all the best!

I appriciate your work aswell!!

Please keep on working on this topic!

Time sync is working great starting with 4.2.0 (thanks to the correct TSC frequency passed to the guest: https://www.virtualbox.org/ticket/10766).

I've prepared a pkg installer for binary distribution but putting binary on this forum it forbidden by the Oracle policy
