Sure, I was replying to this only: "Configuration of each source fits into 64 bits, so if we tried to use KVM_SET_IRQCHIP for configuring a source controller we'd be limited to 64 interrupts per source controller" (I figure 64 is the size of the KVM_SET_IRQCHIP union / 64 bits per entry). Probably you do need a variant of KVM_CREATE_IRQCHIP to create the IOAPICs/source controllers (Paul's proposal at http://permalink.gmane.org/gmane.comp.emulators.kvm.powerpc.devel/5674 for example), assign chip ids to them, set the number of input lines, etc. but the configuration should work well with the existing ioctls, with no limit on the number of sources.
