Explanation about the how multi-version support
for VirtualBox libvirt driver is implemented.
Since VirtualBox adds multiple new features for each release, it is but
natural that the C API which VirtualBox exposes is volatile across
versions and thus needs a good mechanism to handle multiple versions
during runtime. The solution was something like this:
Firstly the file structure is as below:
vbox_CAPI_v2_2.h
vbox_XPCOMCGlue.h
vbox_XPCOMCGlue.c
These files are C API/glue code files directly taken from the
VirtualBox OSE source and is needed for C API to work as expected.
vbox_driver.h
vbox_driver.c
These files have the main logic for registering the virtualbox driver
with libvirt.
vbox_V2_2.c
The file which has version dependent changes and includes the template
file for given below for all of its functionality.
vbox_tmpl.c
The file contains all version specified codes. It implements the
vboxUniformedAPI for each vbox version.
vbox_common.c
The file implement the common driver, with the uniformed api which
defined in vbox_uniformed_api.h and implemented in vbox_tmpl.c
Now there would be a vbox_V*.c file (for eg: vbox_V2_2.c for V2.2) for
each major virtualbox version which would do some preprocessor magic
and include the template file (vbox_tmpl.c) in it for the functionality
it offers.
