My description is not clear again :(
I mean the same vhost thead:
vhost thread #0 transmits packets of flow A on processor M
...
vhost thread #0 move to another process N and start to transmit packets
of flow A
Thanks for clarifying. Yes, binding vhosts to CPU's
makes the incoming packet go to the same vhost each
time. BTW, are you doing any binding and/or irqbalance
when you run your tests? I am not running either at
this time, but thought both might be useful.
I'm using ixgbe for testing also, for host, its driver seems provide irq
affinity hint, so no binding or irqbalance is needed. For guest,
irqbalance is used in guest. I've tried bind irq in guest, and it can
improve the rx performance.
