Make VirtualBox compatibility a top priority

[LaneLester]

Point taken. I did a bug search and found a workaround to the Firefox problem: Bug 5574 – Firefox: in v3.6.8 can't type in the URL field unless you switch focus

So after I start Firefox, if I click on the desktop and then click back to Firefox, I can type in the URL and other fields. So at least I can move forward with some useful things.

The bug is marked as Trivial, but I would think full Firefox functionality is more important than that.

Some time ago I was able to use Guest Additions (GA) with trunk builds without much problems, but then they misteriously stopped to work.
Here you are what happens:
1) Sometimes a dialog box appears during installation of GA, saying that the memory could not be "write".
2) Sometimes installation works, but during the reboot a BSOD always appears. No way to overcome this. It happens also with 0.3.12 boot CD.

There is another problem that happens here, but during the second stage of installation.
When ReactOS setup is registering components, when it reaches mshtml.dll then a dialog box should appear, asking if you want to install gecko plugin.
Instead, when I reach that point, everything freezes, showing a light blue empty screen without any dialog box.
If I select to run it in DEBUG mode (in other words, with text prints to serial port), tipically that dialog box appears and I can complete the second stage of installation, but do not ask me why.
Apparently It seems that slowing down something a bit with debug messages, it helps.

[LaneLester]

I guess the differences in systems is producing some different results.

With the VBox version of ReactOS, the GA executables were in drive D: in My Computer, and I successfully installed GA from there. In the .iso version I've installed in VBox, the D: drive is empty.

The Gecko download went OK for me.

Hi All!

Anyone used ReactOS 0.3.13 with VirtualBox 4.0.4 & VirtualBox Guest Additions lately? I have been trying this for quite sometime now and still get the same bluescreen. Even tried it with the latest SVN builds. I am putting the screen shot of the BSOD here. I would be glad if I can be of any help to fix this.

Hi, check this link: http://www.reactos.org/wiki/Debugging

We need the Serial Debug Output to be able to really help ya.

Strange... We tried the same with 0.3.13 and VBox 4.0.4 on CLT2011 and it worked flawless... except the locked resolution.

[Sof_T]

I used to get bluescreens all the time with Additions. For a while now this has stopped happening for me, I've since upgraded to the latest vBox and still not experiencing this anymore. It used to happen after installation and then opening up a new window.

[Haos]

I am using guest addons all the time and dont have any issues, possibly its because i have VT-x enabled. Could you please confirm if your cpu supports it and if you enable it?

[v_2samg]

Sorry for the delayed response. But here are are couple of things that might be interesting.

@ Haos: It does not have VT-x, but it sure does have AMD-V. I believe VirtualBox supports both.

@ EmuandCo: Ok. Here is the debug info I got off the COM1 port. Had to redirect VBOX COM1 to a raw file.

Try decrasing video ram to a value below 64MB.

Amazing. That helped. I set the video memory to 32 MB and now it works fine. Why didn't I think of that?!!! But here is the thing... If i increase the video memory anywhere close to 60 MB or above, then the results are unpredictable. ReacOS may boot but freeze or go to a black screen. Setting the video memory anywhere >= 63 MB tiggers the blue screen that I posted earlier.

63 MB should work fine, at least with VT-x enabled.

+1.

I coming from VirtualBox community over here, and I hope that ReactOS will have closer cooperation with VirtualBox community.

I tried React OS 0.3.12 on VBox 4.0.4 on Windows 7 x64. (using VT-x)

What doesn't work:
1. Guest Additions Installer GUI is distorted (rendered incorrectly)
2. Shared Folder: ReactOS has necessary functionality for this?
What lacking? Network redirectors in ReactOS Explorer?
3. Seamless mode: Doesn't renders correctly. What is lacking ?
Answer: Dynamic resolution resizing. It is the basic building block for seamless mode.
3.a. Dynamic resolution resizing doesn't work either. ReactOS can support this ?
4. 3D Acceleration: OpenGL
4.a. TuxRacer doesn't even run giving me some error "The Memory could not be read"...
This is a pure ReactOS bug, and it happens even if no GuestAdditions installed.
4.b. Celestia - nothing rendered if 3D is enabled in VBox, giving error message if 3D is disabled in VBox saying that "VBoxOGL" cannot be loaded. In real Windows, this automatically fallbacks to software renderer.
4.c. Really Slick Screensaver:
Some don't work, even if no additions are installed: SkyRocket
With additions this locks up ReactOS, so I don't continue testing.

What works?
0. Guest Additions installer
1. Mouse integration

If you, dear ReactOS community, can fix the issues mentioned above, I will start testing ReactOS more seriously for every major VirtualBox version, and your ReactOS will be included into my OS coverage.

For now, you can see my work on VirtualBox, and enjoy test results with other OSes here.

Hi and welcome! I'm hoping that too.

I tried React OS 0.3.12 on VBox 4.0.4 on Windows 7 x64. (using VT-x)

That's an old version, we have had several fixes after that (0.3.13, or even better: trunk (daily) revisions).

As for your points, I'll answer those I know something about:

1. Guest Additions Installer GUI is distorted (rendered incorrectly)

Every now and then there are graphic glitches, in general not only vbox related, they could be fixed by now, don't know for sure.

2. Shared Folder: ReactOS has necessary functionality for this?
What lacking? Network redirectors in ReactOS Explorer?

The only network support available in ReactOS is TCP/IP, the rest is lacking. It will take some time for this to happen.

3.a. Dynamic resolution resizing doesn't work either. ReactOS can support this ?

This has been implemented after the revision you tested. It's working now.

4.a. TuxRacer doesn't even run giving me some error "The Memory could not be read"...
This is a pure ReactOS bug, and it happens even if no GuestAdditions installed.

Indeed, this game was working, now it is not. It's a known issue (a regression), it's filed here.

4.b. Celestia - nothing rendered if 3D is enabled in VBox, giving error message if 3D is disabled in VBox saying that "VBoxOGL" cannot be loaded. In real Windows, this automatically fallbacks to software renderer.
4.c. Really Slick Screensaver:
Some don't work, even if no additions are installed: SkyRocket

Don't know about this, perhaps one of our guys in win32k can enlighten us.

If you, dear ReactOS community, can fix the issues mentioned above, I will start testing ReactOS more seriously for every major VirtualBox version, and your ReactOS will be included into my OS coverage.

Thanks for testing ReactOS, I expect a lot of those issues to be fixed more or less "soon".

Is there "edit" button on this forum ? I *really* need it.

What doesn't work: (continued...)
5. Copy-paste (Host<->Guest):
Paste work, copy doesn't. I.e. you can paste data from host to ReactOS guest, but not vice-versa.
If one direction is working, making the other direction should be easy for a developer.
Can someone look into it?
6. Multi-Monitor: Not recognized. Is it even supported by ReactOS ?
