virtio-scsi may have lots of LUN, but virtio-blk only has one disk
which needn't lots of hardware queues.
If you want to do queue steering based on the guest VCPU number, the
number of queues must be = to the number of VCPUs shouldn't it?
I tried using a divisor of the number of VCPUs, but couldn't get the
block layer to deliver interrupts to the right VCPU.
