  virtio-serial-bus: Unexpected port id

Status in QEMU:

Bug description:
  With qemu-kvm-0.15.0-rc1 virtio-serial-bus reports an error, and windows 
vdagent can not start.  qemu-0.15.0-rc1 behaves as expected, ie vdagent runs in 
the guest, mouse passes seamlessly between spicec and host and copy/paste works 
between guest and host.
  qemu-kvm has been configured with
  ./configure --target-list=x86_64-softmmu --disable-curses  --disable-curl 
--audio-drv-list=alsa --audio-card-list=sb16,ac97,hda --enable-vnc-thread 
--disable-bluez --enable-vhost-net --enable-spice
  and is started with
  qemu-system-x86_64 -cpu host -enable-kvm -pidfile /home/rick/qemu/hds/wxp.pid 
-drive file=/home/rick/qemu/hds/wxp.raw,if=virtio,aio=native -m 1536 -name 
WinXP -net nic,model -net user -localtime -usb -vga qxl -device 
virtio-serial-pci,id=virtio-serial0,max_ports=16,bus=pci.0,addr=0x5 -chardev 
spicevmc,name=vdagent,id=vdagent -device 
 -spice port=1234,disable-ticketing -monitor stdio

  I've also tried start qemu like
  qemu-system-x86_64 -cpu host -enable-kvm -pidfile /home/rick/qemu/hds/wxp.pid 
-drive file=/home/rick/qemu/hds/wxp.raw,if=virtio -m 768 -name WinXP -net 
nic,model=virtio -net user -localtime -usb -vga qxl -device virtio-serial 
-chardev spicevmc,name=vdagent,id=vdagent -device 
virtserialport,chardev=vdagent,name=com.redhat.spice.0 -spice 
port=1234,disable-ticketing -monitor stdio
  and observed the same results.

  the host runs vanilla kernel.  the guest uses the most recent
  virtio-serial, vga-qxl and vdagent from spice-space.org
