[PATCH 04/10] conf: Pre-fill default ports when parsing network disk sources

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Fill them in right away rather than having to figure out at runtime
whether they are necessary or not.

virStorageSourceNetworkDefaultPort does not need to be exported any
more.
