  qemu                                            1:2.1+dfsg-11                amd64  debian testing
$ sudo /usr/sbin/libvirtd  --version
/usr/sbin/libvirtd (libvirt) 1.2.9
$ /usr/local/bin/virt-viewer --version
virt-viewer version 2.00

I did not run qemu or qemu-kvm, just virsh edit win7, virsh start win7.
Removing these lines lets this run the windows guest again:

<channel type='spiceport'>
       <source channel='org.spice-space.webdav.0'/>
       <target type='virtio' name='org.spice-space.webdav.0'/>
       <address type='virtio-serial' controller='0' bus='0' port='1'/>
     </channel>


Hmmm..... since adding the six lines surrounded by <devices>
and
</devices> tags,

the xml domain file has morphed to having the above 5 lines...

the address line is inserted by virsh edit every time...

I experimented some and found that changing the autogenerated line let it start win7:
       <address type='virtio-serial' controller='0' bus='0' port='1'/>
became
       <address type='virtio-serial' controller='0' bus='0' port='0'/>

So, next I will test if webdav is enabling file transfers.

Thanks,
