I finally figured out how to make it work. I had first built VBox OSE without hardening, but I was getting an error "kernel driver not accessible". Then I trid to build with hardening, but it didn't allow me to use my own files and I didn't want to modify such an integral part of VBox. I rebuilt it without hardening again. This time I tweaked some permissions with /dev/vboxdrv and I reinstalled the package virtualbox-ose-dkms. My host service is now loading successfully.<br>
<br>Thanks to Andreas for telling me how to load my service from within ConsoleImpl2.cpp.<br><br><div class="gmail_quote">On Thu, Jun 17, 2010 at 8:07 PM, Anirudh Bagde <span dir="ltr"><<a href="mailto:anidev.aelico@gmail.com">anidev.aelico@gmail.com</a>></span> wrote:<br>

Thanks for your information. Does this mean I have to modify and rebuild part of VirtualBox OSE?<br><br>I didn't actually build it myself. I used aptitude to download and install the package virtualbox-ose. So what should I do from here?<br>
<br>Thanks again.<div><div></div><div><br><br><div class="gmail_quote">On Tue, Jun 15, 2010 at 3:11 AM, Andreas - Sun Microsystems <span dir="ltr"><<a href="mailto:pentagonik@sun.com" target="_blank">pentagonik@sun.com</a>></span> wrote:<br>

Hi,<br>
<br>
you need to have Main load your service; take a look into src/VBox/Main/ConsoleImpl2.cpp, around<br>
<br>
.<br>
.<br>
.<br>
#ifdef VBOX_WITH_GUEST_PROPS<br>
/*<br>
* Guest property service<br>
*/<br>
<br>
rc = configGuestProperties(pConsole);<br>
#endif /* VBOX_WITH_GUEST_PROPS defined */<br>
.<br>
.<br>
<br>
<br>
or<br>
<br>
.<br>
.<br>
.<br>
Console::configGuestProperties(void *pvConsole)<br>
.<br>
.<br>
.<br>
<br>
That's how we load the service for handling the guest properties.<br>
<br>
Hope this helps,<br>
-Andreas.<br>
<br>

My host is Ubuntu Lucid with VirtualBox OSE and my guest is Windows XP<br>
SP3 with VirtualBox (not ose).<br>
<br>
I want to create a set of programs that will make the VirtualBox<br>
seamless mode work better. To do this, I had to learn how to use the<br>
HGCM. I wrote a small test program for the guest side using C++ and<br>
building it with Visual Studio C++ 2010 Express on Windows. It used<br>
DeviceIoControl to connect and disconnect to the VBoxSharedClipboard<br>
service. It seemed to work, i.e. info.result == VINF_SUCCESS. However,<br>
info.u32ClientID == 0.<br>
<br>
I then decided to write the host service. I compiled a very small<br>
library VBoxBetterSeamless.so that would just notify me if the<br>
VBoxHGCMSvcLoad method was getting called. I verified that the method<br>
was properly exported using readelf. I then put it in<br>
/usr/lib/virtualbox/. VirtualBox OSE doesn't seem to call<br>
VBoxHGCMSvcLoad when the XP VM starts, and I really don't know how to<br>
make the service automatically load every time the VM starts. Google has<br>
not been much help.<br>
<br>
What do I need to do to cause my service to load when the XP VM starts?<br>
<br>
Thanks in advance.<br>
