Thanks for the response. I should have said in the original post that the -mem-path and -mem-prealloc flags do not do what I need them to do. Using the -mem-path flag passes the hugepage to the guest but does not make the hugepage still available to the host. I want to be able to allocate hugepages on the host and then map those into the guest where both the host and guest can access the same memory/hugepage. So making a change on the host will make the same change on the guest. Or, as in my application's need, I run the host application which allocates and initiates memory structures, and I want those structures to be used by the application running in the guest.
