Did you set the affinity manually in your experiments, or perhaps there
is a difference between scsi and networking... (interrupt mitigation?)

You need to run irqbalancer in guest to make it actually work. Do you?

Yes, of course, now on to debugging that one.  I just wanted to ask

It was indeed an irqbalance bug, it is fixed now upstream.
