What were you trying to do that didn't work?

We are trying to support windows11 on aarch64, One problem we are facing is libvirt cannot emulate USB CD-ROM drive, which prevents installing Windows and virtio drivers， we can only use qemu-command line to achieve it:

-device usb-storage,drive=inst  
-drive file=virtio-win.iso,media=cdrom,if=none,id=iso  
-device usb-storage,drive=iso -drive file=win11.qcow2,if=virtio  

  <qemu:commandline>
    <qemu:arg value='-device'/>
    <qemu:arg value='usb-storage,drive=inst'/>
    
    <qemu:arg value='-drive'/>
    <qemu:arg value='file=virtio-win.iso,media=cdrom,if=none,id=iso'/>
    
    <qemu:arg value='-device'/>
    <qemu:arg value='usb-storage,drive=iso'/>
    
    <qemu:arg value='-drive'/>
    <qemu:arg value='file=win11.qcow2,if=virtio'/>
  </qemu:commandline> 

What is the impact of this issue to you?

Please provide the package NVR for which the bug is seen:

libvirt-11.3.0-1.el10.aarch64
kernel-6.12.0-89.el10.aarch64
qemu-kvm-10.0.0-4.el10.aarch64

Backgrounds: 

• Virtio-win QE have done some tests on Windows 11 with downstream qemu-kvm ARM64, there are some general problems see refer
