hi
 I read checkpoint code
 when checkpoint or migration ends,guestos continues processing by 
returning back from hypercall of suspend, that is ,take_machine_down() 
call the post_suspend() to continue ,is it right?
 while in post_suspend(),pfn_to_mfn_frame_list_list[] is converted by 
virt_to_mfn(),why do this convert? i could not find where it has been 
converted,and why should it be converted back?
 and in the xc_domain_restore()in the dom0,pagetable has been 
uncanonicalized, which is coupled with canonicalization in 
xc_domain_save(),is it ? ,and what is the reasons for 
pfn_to_mfn_frame_list_list[] virt_to_mfn in post_suspend()?
 could you help me

thanks
