Unexpected port id 2909357808 for device virtio-serial0.0
Description of problem:
when the VM runs for a period of time.qemu log always print the error：“Unexpected port id 2909357808 for device virtio-serial0.0”.And the spice connet display black screen.Restart the vm,it recovery. my channel is 16,Normally it will always output port less than 16,but when error it report a lage port. why it get a lage port "2909357808",Is there a data overflow?
Steps to reproduce:
1.The VM runs for a period of time

2.report the error: "Unexpected port id 2909357808 for device virtio-serial0.0".

3.restart to recovery.
Additional information:
qemu log:

when vm is ok:
