I want to try one more thing: leaving the Fedora guest on NAT and changing the Windows guest to macvtap (since I don't need to connect into it).
Interesting. I changed the Windows guest to macvtap and didn't touch the Fedora guest. Starting with both guests shut down, the Windows guest comes up (though it doesn't have a local IPv4 address from the host's viewpoint, as expected). However the Fedora guest - still on NAT - doesn't have an IPv4 address either and is completely disconnected.
dnsmasq (libvirts's version) is running normally. Both guests have IPv6 addresses and respond to ping6's.
I'm getting a growing feeling that something is really screwed up with my installation of libvirt. I hesitate to wimp out and reinstall it, but I'm running out of ideas.
