A few comments: You should put #include <config.h> at the very top of all your C files (before any other headers/defines), to avoid warnings. There was one place where you'd used virFreeStoragePool, which should be virStoragePoolFree. Functions such as 'virDomainDestroy' have changed their semantics in that they now free the virDomainPtr object. I understand why you do this (the domain no longer exists, so the object cannot be used), but it is a big change from the p.o.v. of those of us using proper garbage collection, and moreover it's an ABI change. Existing correct code which did 'virDomainDestroy (dom); virDomainFree (dom);' could now segfault.
