There is no need for adding this signal. We already have appropriate signals for the relevant libvirt events ("stopped::saved" in this case). Besides you are not emitting this signal.

You need to duplicate (g_strdup) the 'custom_xml' and 'filename' strings when you put them in the data and then free them here.

Its hard to be sure with this gmail's web interface but I think last 2 arguments aren't aligned. Please do read the HACKING file and read through your code/patches to see if it follows the conventions.

Beware that this file (unlike the rest of the code) uses tabs rather than spaces for indenting. BTW, commit log summary could just be: Add bindings for virDomainSave*(). -- Regards, Zeeshan Ali (Khattak) FSF member#5124
