router@utils_server:~$ virsh -c qemu:///system dumpxml router | grep -A4 scsi
router@utils_server:~$ virsh -c qemu:///system dumpxml router | grep -A4 -i scsi
router@utils_server:~$ virsh -c qemu:///system dumpxml router | grep -A4 -i virtio
      <target dev='vda' bus='virtio'/>
      <alias name='virtio-disk0'/>
      <address type='pci' domain='0x0000' bus='0x05' slot='0x00' function='0x0'/>
    </disk>
    <controller type='usb' index='0' model='ich9-ehci1'>
      <alias name='usb'/>
--
      <model type='virtio'/>
      <alias name='net0'/>
      <address type='pci' domain='0x0000' bus='0x08' slot='0x00' function='0x0'/>
    </interface>
    <serial type='pty'>

    <memballoon model='virtio'>
      <alias name='balloon0'/>
      <address type='pci' domain='0x0000' bus='0x07' slot='0x00' function='0x0'/>
    </memballoon>
  </devices>

there is no scsi in the xml, if I define one, will it show up as an additional or will change the existing one?
