Re: [Xen-devel] vmcs_revision_id: do we care?

[Daniel Li <dli@xxxxxxxxxxxxxxx>]

Based on what I've heard, both IBM and Intel have been telling people 
this configuration is valid.  From what I was able to dig out, Intel in 
their System Programming Guide: Virtual Machine Monitor Programming 
Considerations, published Nov. 2007, suggested when loading a VMCS onto 
a processor with a different vmcs_revision_id, instead of using VMPTRLD, 
one should use VMREAD to read out each field then use VMWRITE to write 
them back. Is that more or less  the kind of work we are facing here? Or 
is there more?
Thanks,
Dan
