Probably a FAQ.

I have implemented a prototype:

QEMU event for an in-guest issue (tools installation / crash etc), via fwcfg / vmcore (similar). (QEMU_PROCESS_EVENT_DBGTOOLS_CHANGED).
Qemu Process / QemuMonitor handling for same event.
Mapped this through to VIR_DOMAIN_EVENT_ID_DBG_TOOLS,
Corresponding changes to top level event handling.

We would find this *very useful* in cases where vm migration, debugging and the like require co-operation with guest user-mode.

Are you folks happy to countenance some simple, but top-level, event handling changes triggered by guest software, or is this considered a no no? Should I be burying the details somewhere in EVENT_TUNABLE instead?

Patchsets also available ...
