Note the names are not really important. libxen-hcall Library for exporting hypercalls. libxen-idc Library for interdomain-communication primatives (providing the Sys-V IPC mechanisms seems like a reasonable start). libxen-store Interface for interacting with the domain store. Persisting daemons and these sorts of things link against this. libxen Management tool interface. Provide high-level functions that authors of management tools would expect. In most cases, this would be all that would be needed to link against. Developers can link against lower level libraries if necessary. All libraries should use autotool, pkg-config, proper versioning info, etc. All interfaces should be documented (this is a requirement of EAL besides being good practice). We could begin work today on libxen-hcall and libxen-idc while we work out what the store is going to like and how the OF structure is going to work. Thoughts?
