When I configure like this, from a linux guest point of view I get this
Symbios Logic SCSI Controller:
00:08.0 SCSI storage controller: LSI Logic / Symbios Logic 53c895a
But htis is true only if you add the SCSI controller too, not only the disk
definition.
In my case
<controller type='scsi' index='0'>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x08'
function='0x0'/>
</controller>
Note the slot='0x08' that is reflected into the first field of lspci inside
my linux guest.
So between your controllers you have to add the SCSI one
In my case (Fedora 25 with virt-manager-1.4.1-2.fc25.noarch,
qemu-kvm-2.7.1-6.fc25.x86_64, libvirt-2.2.1-2.fc25.x86_64) with "Disk bus"
set as SCSI in virt-manager, the xml defintiion for the guest is
automatically updated with the controller if not existent yet.
And the disk definition sections is like this:
<disk type='file' device='disk'>
<driver name='qemu' type='qcow2'/>
<source file='/var/lib/libvirt/images/slaxsmall.qcow2'/>
<target dev='sda' bus='scsi'/>
<boot order='1'/>
<address type='drive' controller='0' bus='0'
target='0' unit='0'/>
</disk>
So I think you should set dev='sda' and not 'hda' in your xml for it
I am actually very curious to know if that would make a difference. I
don't have a such windows vm images ready to test at present.

I don't kknow if w2016 contains the symbios logic drivers
already
installed, so that a "simple" reboot could imply an automatic
reconfiguration of the guest....
Note also that in Windows when the hw configuration is considered heavily
changed, you could be asked to register again (I don't think that the IDE
--> SCSI should imply it...)
