I installed virt-viewer (which I didn't know about), however the display is 
black (i only see a cursor)

I did attach the USB device with it and debug shows this:

I am having issues with attaching display with spice, but I saw no errors on 
attach of USB device, I just am not able test this.

XML:

  <qemu:commandline>
    <qemu:arg value='-set'/>
    <qemu:arg value='device.redir0.debug=4'/>
  </qemu:commandline>

QEMU Line:

redir,chardev=charredir0,id=redir0 -device virtio-balloon-
pci,id=balloon0,bus=pci.0,addr=0x6 -set device.redir0.debug=4
