Xen devel - Nov 2008 - Issues in call to get_domain_by_id()

Hi all,

I am new to xen. I need to write a program which sits in dom0 and reads the domU
page tables. I basically need a list of virtual pages which are are mapped onto
a domU at any instant. Please let me know the best approach to do this?

Currently I am using control interface (libxc) to get list of pfns by calling
xc_get_pfn_list. The stupid that I am having now is that if i try to call any
function (eg: get_domain_by_id) defined in sched.h or xen.h, I get following
error at compile time
undefined reference to get_domain_by_id'' 

I am currently linking -lxenxtrl -lxenguest -lz -lpthread libraries from gcc. Is
there any other library that I need to link at compile time to call? Please help
me out here. Any help would be appreciated.

Thanks,
Bhavani

You can''t get at Xen-internal functions from outside Xen.
