Oooh, that is a looong explanation. If you want to peek at it, see 
http://publibz.boulder.ibm.com/epubs/pdf/a2278324.pdf . Chapter 6 
covers Interruptions. I'd recommend to start with reading external 
interruptions, because that is the one we'll be primarily be using 
with kvm. External interruptions are used for things like timers, 
hypercalls, and IPIs. The "Program Interruption Coditions" are also 
worth reading, they cover things similar to general protection fault 
on x86. Chapter 11 covers a different type of Interruptions, such as 
error detection of hardware failures and hot-standby component 
failover. Chapter 16 is also of interrest, it covers I/O interruptions.

Whenever you see me in person (next kvm forum maybe?), you are invited 
to a lot of beer: I'll bring pen and paper and try to give you an 
overview while we get drunk :-).

so long,
Carsten
