Hi Roger & Jan,
I got my test env back, and back the patch to stable-4.12, run same
test, I still seen original issue, guest kernel printed error:
kernel:do_IRQ: 20.114 No irq handler for vector (irq -1)
After that, pass through infiniband VF stopped to work.
My patch as below, please check:

those vectors could get wrongly injected at a later point when the MSI
fields are already updated.
