I wonder how valid his message is. We actually write this MSR with
all ones during boot.
However, considering involved functions like
nb_mce_bank_enabled_on_node() or node_to_amd_nb() taking
node IDs as inputs, and considering that PV guests (including
Dom0) don't have a topology matching that of the host, I doubt
very much that this driver is even remotely prepared to run
under Xen. It working on Xen 4.1.x would then be by pure
accident.
