[Xen-devel] Max gpfn for PV guests

["Aravindh Puthiyaparambil (aravindp)" <aravindp@xxxxxxxxx>]

I am trying to find out the max pgfn for a 256MB PV guest. If I call xc_domain_getinfolist() and look at xc_domaininfo->max_pages, I get 0x10100. If I call xc_domain_getinfo() and look at xc_dominfo->nr_pages, I get 0x10000. Within the hypervisor if I call domain_get_maximum_gpfn(), I get 0xffff. So it looks like xc_domain_getinfo() is returning the correct value. Why is xc_domain_getinfolist() returning a different value? Which value should I be looking at for the max gpfn?

 

Thanks,

Aravindh
