[Xen-devel] [PATCH v3 05/19] libxl: add vmemrange to libxl__domain_build_state

[Wei Liu <wei.liu2@xxxxxxxxxx>]

A vnode consists of one or more vmemranges (virtual memory range).  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.
