Pre-existing - but should we do the VIR_STRDUP into a temporary before
freeing the original, and only replace on success, so that at least on
an OOM situation we still leave the older string in vm->def rather than
losing both strings? On the other hand, OOM recovery is best effort,
and someone should already be prepared for weird things to have happened
to their guest. Certainly not something to change in this patch.
ACK.
