In the past there have been hard to recreate issues where XIVE changes
cause qemu crashes due to multi-socket interrupts such as in [1].
Add a functional test explicitly to test whether remote interrupts
work.
The test can also work as additional boot test for multi-socket boot,
initrd boot test, as well as a check for e1000e to be working in
powernv,
you should consider moving to a more modern nic model: igb, which
has sr-iov support too.
yes, can do. with igb i see multiple irqs, so test will have to take sum
of all rx irqs, and compare:

I feel e1000e suffices for this test, should i stay with e1000e or use
igb here ?
or use a single cpu per socket config. Which seems better for the test.
The test uses single cpu per socket, since i have `-smp
4,sockets=4,threads=1`. Was this what you meant ?
Thanks,
