Thanks Keir, I was headed in that general direction, but I was hoping to 
get lucky.

I setup the serial cable and did a number of backtraces.  I'm hoping that 
the backtrace for the host is correlated with the client backtrace, but 
I'm suspicious.  Some of the backtraces I got list my client (e.g., on 
CPU1) but don't list a CPU1 host state.  In all cases my clint is doing 
what I expect (attempting to execute an fnsave instruction).

I slurped the relevant host stacktraces from the console debug log, and I 
don't see a pattern (again hoping to get lucky).  I'll put away my private 
OS shovel, and see if I can start fashioning a Xen shovel.  If you see 
something obvious below that looks suspicious, let me know, otherwise I'll 
see what my Xen shovel digs up.  Thanks again for your help.

Host CPU traces from the CPU's associated with my OS client.
