Folks,
Please find the result of upstream testing. This time we got a kernel panic
error while compiling mainline kernel (3.5.rc7). Hence we could verify only
mainline qemu-kvm.

In order to inject a level interrupt from an external source using an
irqfd, we need to allocate a new irq_source_id. This allows us to
assert and (later) de-assert an interrupt line independently from
users of KVM_IRQ_LINE and avoid lost interrupts.
We also add what may appear like a bit of

When a linux guest live migrates to a new host and subsequently
