Hi guys,
We got a BUG report from our testers yesterday, the testing scenario was
migrating a VM (Windows guest, *4 vcpus*, 4GB, vhost-user net: *7 queues*).
We found the cause reason, and we'll report the BUG or send a fix patch
to upstream if necessary( we haven't test the upstream yet, sorry... ).
We want to know why the vhost_net_start() must start *total queues* ( in our
VM there're 7 queues ) but not *the queues that current used* ( in our VM, guest
only uses the first 4 queues because it's limited by the number of vcpus) ?
Looking forward to your help, thx :)
