Right.  The real problem here is that virt-manager is still using 
python2, which long past EOL, and is planned to be removed.

The current plan, per [1] is for virt-manager to become uninstallable 
after this, and see if anyone complains.

If virt-manager is important to you, perhaps you could help us bring it 
up to date?

I guess I will have to adopt the virt-manager package... please put it on my plate :(

Well, that wasn't quite the response I was expecting, but thanks very 
much for helping!

I have added 'virt-manager' to your packages.

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.
