Hi qemu team： Recently, during the development based on virtio net/vhost net, it was found that when virtio enabled multiple queues, there was always another queue whose interrupts were not triggered, and no useful logs were found. The interrupt statistics in Guest are as follows:
CPU0 CPU1 CPU2 CPU3 CPU4 CPU5
CPU6 CPU7 CPU8 CPU9 CPU10 CPU11 CPU12
CPU13 CPU14 CPU15 CPU16 CPU17 CPU18 CPU19
CPU20 CPU21 CPU22 CPU23 CPU24 CPU25 CPU26
CPU27 CPU28 CPU29 CPU30 CPU31
