libvirt users - May 2018 - Re: changing pci addr of SCSI storage controller: Red Hat, Inc Virtio block device (rev 01)

Greetings,

when execute lspci inside my vm linux guest, I see this:
:/# lspci | grep -i scsi
03:00.0 SCSI storage controller: Red Hat, Inc Virtio block device (rev 01)

I don't see any such address in my xml file, is it possible to move that
controller to another pci addr?

Thanks,

Dagg.

Can you look again?
Libvirt should not be adding virtio-scsi devices to the VM without
putting them in the XML as well. If you did not have it in the XML when
you defined the domain and it got auto-added because there was a SCSI
disk with no controller, the controller should still show up in the
output of virsh dumpxml / virsh edit:
    <controller type='scsi' index='0'
model='virtio-scsi'>
      <address type='pci' domain='0x0000' bus='0x03'
slot='0x00' function='0x0'/>
    </controller>

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