Re: [Xen-devel] code read problems
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
