Stefan Hajnoczi 4907644841 Hi,
"Host Memory Backends" and "Memory devices" queue ("mem"):
 - Support and document VM templating with R/O files using a new "rom"
   parameter for memory-backend-file
 - Some cleanups and fixes around NVDIMMs and R/O file handling for guest
   RAM
 - Optimize ioeventfd updates by skipping address spaces that are not
