(vcpus_in_sie == 0) > Mimu, we just spoke about -- thus a reminder for us, and a FYI for the rest. vcpus_in_sie != 0 does not necessarily mean that FW can deliver GISA interrupts to the guest (and thus we don't have to dispatch a suitable vcpu): if all cpus in SIE mask IO interrupts it does not really matter that they are in SIE. I.e. we should still get alerted and try to dispatch an eligible vcpu. Regards, Halil
