Hi,
for development purposes you should disable hardening. Use
--disable-hardening for that. If you want ship the resulting OSE package
you have to enable hardening again and therefor you have to add your new
file to SUPR3HardenedVerify.cpp.

I managed to build from scratch VirtualBox OSE. It wasn't building
before because some dev packages needed to be installed. I modified
ConsoleImpl2.cpp to load my library and rebuilt VBoxC.so. However, in
the log file, I get:
00:00:00.834 supR3HardenedLdrLoadIt: Verification of
"/usr/src/virtualbox-ose-3.2.0-src/out/linux.x86/release/bin/VBoxBetterSeamless.so"
failed, rc=VERR_NOT_FOUND
I looked in the source files and I saw that my file apparently wasn't in
a verification table (g_aSupInstallFiles) in file
SUPR3HardenedVerify.cpp. Must my build of VBox OSE not be hardened
before I can do this, or should I modify SUPR3HardenedVerify.cpp to
include my library?

Thanks for your information. Does this mean I have to modify and
rebuild part of VirtualBox OSE?
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?
Thanks again.

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

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