[Xen-devel] Memory Sharing
Hi,er
I am playing with memory sharing functions (nominate & share), for my
research project. In my project, i get the GFNs of starting & ending
pages of kernel code segment using xc_translate_foreign_address and
then using a loop i nominate the memory pages of kernel code segment &
share them.
Both nominate & share() functions returns 0, on most sharing requests
(almost 99%).
My problem is that after sharing the memory, all of the other domUs
except the domU which is used for getting the handles (shandles) for
sharing memory pages are frozen, if i start one VM after another and
try to share code pages after VMs have logged in. If i try to run the
same procedure on already started set of guest domains, the VMs will
be restarted (except the shandle domU).
So what could be the reason for this?
I'm using Xen -4.1.1-rc3-pre.
Thanks,
Harshan
