Re: [Qemu-devel] Mapping Hugepage to Guest

[Haines, Brent R]

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.
