Hm.  In TianoCore settings, I've *disabled* "try secure boot".  As I 
said, I'm not convinced yet that's working correctly.  It'd clearly NOT 
write to a read-only mounted installer image, leaving a write to NvVars 
in RAM.  I don't know if/how that's handled in a Xen guest ... digging 
around about that now.
I've tried to engage with the OpenSUSE Xen folks re: launching Debian 
guest launch.  So far, not a peep ...
