F15 libvirt net-edit will not use static dhcp addresses for dnsmasq

In Fedora 15 I'm trying to set up statically-assigned DHCP addresses
for virtual machine domains, but libvirt does not pass this on to
dnsmasq.
I tried to edit the network xml definition file using
# virsh -c qemu:///system net-edit vmnet
I changed it from this:
<network>
<name>vmnet</name>
<uuid>d27e8fa9-d358-b505-fc7b-4fb0ec0e7c4f</uuid>
<forward dev='eth0' mode='nat'/>
<bridge name='virbr1' stp='on' delay='0' />
<ip address='192.168.4.1' netmask='255.255.255.0'>
<dhcp>
<range start='192.168.4.128' end='192.168.4.254' />
</dhcp>
</ip>
</network>
by adding a couple <host> elements, into this:
<network>
<name>vmnet</name>
<uuid>d27e8fa9-d358-b505-fc7b-4fb0ec0e7c4f</uuid>
<forward dev='eth0' mode='nat'/>
<bridge name='virbr1' stp='on' delay='0' />
<ip address='192.168.4.1' netmask='255.255.255.0'>
<dhcp>
<range start='192.168.4.128' end='192.168.4.254' />
<host mac='52:54:00:e8:dc:ee' name='aaa.example.com' ip='192.168.4.32' />
<host mac='52:54:00:22:6c:5c' name='bbb.example.com' ip='192.168.4.33' />
</dhcp>
</ip>
</network>
After saving the file I do get the message
"Network vmnet XML configuration edited."
However, if I immediately net-edit it again, the <host> elements are
not there as if I had not changed it.
This also has the effect that the dnsmasq daemon is started without
having any of the command line options of "--dhcp-host" or
"--dhcp-hostsfile". Which means that the virtual domains do not
receive static IP addresses.
Also of note, when using net-edit if I also try to change anything
else, such as the dhcp start ip address, it too will get reverted back
after I save it.
Does anybody know what I may be doing wrong?
The package version is libvirt-0.8.8-4.fc15.x86_64
Thanks.
