What logging options can I specify for VBoxSVC.exe with VirtualBox release builds?
I'm experiencing consistent program initialization failures with VirtualBox 5.x and the new 6.0 builds (OpenSourceEdition) on Windows 7 64bit, and after a whole week of trying it seems the only way to figure out the culprit is to do some logging for the main component, VBoxSVC.exe, and I had to look elsewhere as the official docs gave very little information on that.
I receive a COM error E_NOINTERFACE upon involing the main GUI. After some analysis I can conclude that either VBoxSVC.exe failed to instantiate IVirtualBox and kept silent about that, or inter-process COM communication went wrong (but all other COM applications on my system works fine).
And below goes my questions in detail:
- Is “logging of COM components” (as seen in official docs) of VBoxSVC.exe possible in release builds? (I am not in the position of building a Debug version anyway.)
- Which logging groups, flags and switches (if any) are recommended for my purpose? To be precise: logging for (1) tracing the entire
IVirtualBoxinstatiation process in the VBoxSVC class factory and (2) monitoring allQueryInterfacecalls on the ProxyStub marshalling interface on both C/S. - How do VBox / IPRT logging differ? What is Sander / Bird logging? How is Log-level defined and used in VBox? Didn't find docs for them.
BTW, there shan’t be any hardware issue -- I have several machines of same hardware, VirtualBox runs flawlessly on the rest of them.
