  • Thread-topic: several Qs about domain live migration

Is analysis_phase just for debug purpose, since 'runs' is just zero
when invoked?

Where is the possible place to mark pfn_type to as some special 
type for hvm domain, like invalid pfn?
if ( hvm )
        pfn_type[batch] = n;
else
        pfn_type[batch] = pfn_to_mfn(n);

I didn't find code to check mmio holes. Then how does restore
side differentiate normal ram from those holes, for a hvm with
>4G memory?

Thanks,
Kevin
