Hi
I try to understand the eventchannel part,
and I am confused by the differences of the physical IRQ line ,virtual
IRQ line and virtual IPI line

for a vm , what do the physical IRQ line and virtual IRQ line mean for?
Every vm has one or some vcpu ,then virtual IRQ line may be related with
one of these vcpu , then what is the physical IRQ line for?
I am really confused with it



could someone give me help
Thanks in advance
