Virtualbox Configuration Manager

[burhan]

I am trying to use the cfgm.cpp functions like CFGMR3QueryBytes( ) to access data from the configuration xml file but it just crashes the VM before even starting. The log says CFGMR3QueryBytes( ) is undefined symbol. I have included the necessary header files. I also looked at DevPCNet.cpp which is using the same functions in its pcnetConstruct( ) function successfully.

Here is the last few lines of the log

libvirtdevice.so is the binary of my virtual device which I am writing on my own and adding it to Virtualbox. Everything was working fine and the file would load just fine before I tried to use the configuration manager functions.

Moved to VirtualBox API

This really belongs on the dev mailing list. Make sure to explain in detail what you are trying to achieve and then how you are trying to achieve it and how things fail. Include a full log file, not just part of it.

[burhan]

What do you mean by dev mailing list? And how do I include the whole log file ? Copy and paste it ?

[noteirak]

I mean this and you use e-mails, so you just attach your file to it.
