Your patch is correct.

But I'd suggest to replace the 'return NULL' with a 'goto cleanup'
here instead of adding a virConfFree, as this is more in line with the
surrounding code.

Either way ACK.

Yeah, 'def' has a initial value 'NULL', so 'goto cleanup' is perfected
instead of adding a virConfFree.

Matthias, thanks for your good suggestion, I will commit v2 patch for this.
