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.
