<p>Yes, the support to from SCSI has been removed in recent versions of qemu.</p>
<p>You can try to attach the disk to sdb directly, then. (You may need to generate a template file with DISK=[ IMAGE=..., TARGET=sdb] if you are using the CLI), and let see if that solve the issue.</p>

Hi,<br>
<br>
thanks for reply, but if I change image to DEV_PREFIX=sd and
template to TARGET=sd, the VM doesn't boot (see an attached picture)
:-(<br>

<div>Automatic device mapping, KVM and hot-plugging is a bit
tricky. As you see from your log the VM behaves as a physical
host, hotplugging is only supported for the SCSI bus.</div>
<div><br>
</div>
<div>Now, OpenNebula automatically compute target per bus. If your
VM template uses hd it will take hda for the first OS. A
hot-plugging operation (target=sd) may collide with the first
OS disk...</div>
<div><br>
</div>
<div>Could you try to use DEV_PREFIX=sd for both the OS image and
the attaching volume (target=sd + DEV_PREFIX=sd in the Image
template or in the DISK attribute in the VM template).</div>

I have one running VM with W2008R2 Server and second VM

I see that disk in sunstone interface

I'm able to do it with existing image too.<br>
