HI,

I am using kvm-kmod with version 2.6.36, but I encountered a fatal problem.
In linux run on KVM,I using request(irq,*,*,*) function to request a
interrupt line. However, When I using a irq bigger than 15, it will
return error.
Now I have simulated a PCI device and decide to using IOAPIC to send
interrupts.So I decide assign 20,21 line for my device . but in guest
os linux I could not request these number for my device.
I know PIC just have 16 interrupt lines. I am not sure if the KVM
really support APIC, and how to request a irq line more than 15?

Waiting for your help on line.
Thanks..

Shawn.
