Hi,
Can anyone guide me on how to compile Xen with Infiniband support?
(Particularly Mellanox)
I want to perform some RDMA read/write functionality from within the Xen
code (it is for a course project) using the Verbs API.
Thanks,
Gohar

Is it possible to increase the number of pages (or memory size) visible to
the guest OS (domU)? Perhaps at boot-time?
Can this be achieved by increasing the value of nr_pages in the start_info
struct when it is initialized? Where exactly in the code is this happening?
Thanks

Sorry, my apologies. I got it now, thanks!

Inside the page fault handler for shadow page tables (sh_page_fault
function in multi.c) where is the code for swapping in a page from disk?

Where does Xen maintain the page table for each VM? The mapping of page
number to frame numbers, basically.

I'm also working on a similar thing - can you please tell me how you copy
the memory pages from one part of the memory to another?

What is the alternate of doing a malloc in Xen?
I have a data structure (containing a list from the list.h implementation) and
I want to initialize a pointer and allocate space for my struct. But since
malloc doesn’t work in Xen, what should I do?
Thanks

Given two GMFN in shadow paging (HVM) is there a way to swap their
contents? Let's say I have GMFN x and GMFN y, I want to put the contents of
x in y and the contents of y in x.

tanding is that it can be done in the page fault handler of shadow
page tables. I have mentioned the relevant file and function earlier in
this thread.
Thanks a lot!

It is for a project, I'm trying to experiment with a couple of things.
Could you please guide me how this could be achieved? Some relevant chunks
of code, perhaps?
Thanks!

Hi All,
I want to know if, in the case of HVM (shadow page tables), we can change
the machine frame number pointed to by a page table entry?
An overly simplified example would be: let's say I have page number 10 that
is pointing to machine frame number 10, but I would like it to point to
machine f
