Red Hat Bugzilla – Bug 1286515
A queue does not generate interrupts inside guest when booting guest with mq + vhost-user
Last modified: 2017-03-09 18:57:37 EST
With the latest code, i test it with 4 queues between guest to guest,
every queue get interrupts only when i set both queues of the guest to 4 queues,
1 queue send to 4 queues will miss the interrupt as the title.
FuXiangChun, Can you test it again please with the latest 7.3 and ovs-dpsk?
I believe we should Close it as Current-Release.
It should only work for the case where the number of queues is identical on both ends.

Can QE share a test bed with me? i'm using a kernel compiled from 4.1.0 and latest upstream dpdk/ovs code by myself, i'll try it.
Have a draft test for both rhel as xfu listed and the same version with mine test bed on xfu's machine, can't get all interrupts generated on every queue,
will check it out again.
