One example of multiple vmemranges is that there is a hole in one vnode. Currently we haven't exported vmemrange interface to libxl user. Vmemranges are generated during domain build, so we have relevant structures in domain build state. Later if we discover we need to export the interface, those structures can be moved to libxl_domain_build_info as well. These new fields (along with other fields in that struct) are set to 0 at start of day so we don't need to explicitly initialise them. A following patch which introduces an independent checking function will need to access these fields. I don't feel very comfortable squashing this change into that one so I didn't use a single commit.
