But........I am still utterly baffled by guest networking.

What I *want* to do is have a Windows XP guest that runs on the same network
as my laptop, the host; in other words, the guest should be able to access
all the network that the laptop can see. But I can't for the life of me find
out how to do this.

I'm fairly sure this is not possible. Guests created with virt-manager (ie. libvirt) will want to talk to the bridge created by libvirtd. ie. They'll be started up with the following qemu -net options:

/usr/bin/qemu-kvm [...]
  -net nic,macaddr=00:16:3e:86:61:81,vlan=0
  -net tap,fd=12,script=,vlan=0

Networking is handled through a bridge (usually called virbr0) and IP addresses are assigned from a "private range", by default 192.168.122.X. The assignment of addresses and NAT to the "outside world" is done by a dnsmasq process.

All of this means that the Windows guest won't be on the same network as the host, ie. broadcasts etc won't work.
