Rusty Russell df60aeef4f lguest: use eventfds for device notification
Currently, when a Guest wants to perform I/O it calls LHCALL_NOTIFY with
an address: the main Launcher process returns with this address, and figures
out what device to run.

A far nicer model is to let processes bind an eventfd to an address: if we
find one, we simply signal the eventfd.

This is a very simple module which allows you to run
multiple instances of the same Linux kernel, using the
"lguest" command found in the Documentation/lguest directory.
Note that "lguest" is pronounced to rhyme with "fell quest",
not "rustyvisor". See Documentation/lguest/lguest.txt.
