This patch is an evolution of the previous patch for implementing DHCP host mappings. The virNetworkListDHCPHostMappings calls has been changed to take three arrays of strings: int virNetworkListDHCPHostMappings (virNetworkPtr network, char **const hwaddrs, char **const ipaddrs, char **const hostnames, int maxmappings); Also I've fixed a number of bugs throughout, particularly in the way that the hosts file was being parsed. This patch is for discussion only. There is a segfault on the client side of (perhaps ironically) the virNetworkListDHCPHostMappings call. Been looking for about an hour but I can't see it yet ... All the other calls appear to work OK. Rich. -- Richard Jones, Emerging Technologies, Red Hat http://et.redhat.com/~rjones virt-p2v converts physical machines to virtual machines.
