Wido den Hollander c565db2cf2 kvm: Set amount of queues for Virtio SCSI driver to vCPU of Instance (#3101)
The additional queues can enhance the performance of the VirtIO SCSI disk
and it is recommended to set this to the amount of vCPUs a Instance is assigned.

  The optional queues attribute specifies the number of queues for the
  controller. For best performance, it's recommended to specify a value matching
  the number of vCPUs. Since 1.0.5 (QEMU and KVM only)
