Nope, the monitor is redirected so that libvirt can send commands
to it directly.

However, support for usb device attach/detach was just added to
libvirt, so you won't need to directly talk to the monitor to do
this. You should be able to do something like the following for
a usb disk:

cat << __eof__ > disk.xml
    <disk type='file' device='disk'>
      <source file='/path/to/diskfile'/>
      <target bus='usb'/>
    </disk>
__eof__
virsh attach-device some-active-domain disk.xml

I haven't tested this so no guarantees, and you'll need current
upstream libvirt. Hopefully this will be in virt-manager soon
though so it will be nice and easy :)
