So, cleaning up the final python2 bits, I got around back to looking at 
this again.  I've made minor updates to python-libvirt and virt-manager, 
which gets something which runs.

But it just sits there, apparently trying to connect to a local QEMU 
hypervisor I don't have, but that's what the previous, python2 version 
does as well...

I'm guessing that perhaps the only sensible way to run this on Cygwin is 
with the '--connect' option to a remote hypervisior.  Or maybe it's 
totally broken.
