Hi,

I need to call xc_core_arch_map_p2m to get the pages for dom0. This is my code

 domctl.cmd=XEN_DOMCTL_getpageframeinfo;
 domctl.domain=0;

xc_domain_getinfo(xc_handle,0,1,&info);
live_shinfo = xc_map_foreign_range(xc_handle, info.domid,PAGE_SIZE,PROT_READ, 
info.shared_info_frame);
sts = xc_core_arch_map_p2m(xc_handle, &info, live_shinfo, &pfn, &p2m_size);

I get the following error for dom0.
xc_map_foreign_range: ioctl failed: Bad address

The same code runs for domU's. How do i get list of pfns for dom0?
Please help me out here.

Thanks,
Bhavani
