yes, i using callbacks for errors, for now just copypasted example callback to
print errors
static void libvirt_error_handler(void *userdata, virErrorPtr err)
{
fprintf(stderr, "Failure of libvirt library call:\n");
fprintf(stderr, " Code: %d\n", err->code);
fprintf(stderr, " Domain: %d\n", err->domain);
