I can't think of any reason why the callers of libxenstore should need to care about how which communication channel gets used so there's no reason for the library to defer that choice to the caller. So perhaps we should go one step further push this behaviour down into libxenstore itself? i.e. add "xs_open(int ro)" and make xs_{daemon,domain}_open{,_readonly} compatibility aliases to that function. Unfortunately, there is practical difference between the socket and the page interface. Which is the reason why every xs connection in xapi are sockets; IIRC polling for events on the page interface didn't really work; I think there was at least 1 other practical differences, but it seems to have eluded me. -- Vincent _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
