How to configure a libvirt network in %post (virsh fails due to libvirtd unable to run)

Hi,

I am trying to do something like this in the %post section of the 
kickstart file for my F16 workstation:

# setup libvirt network
cat > /home/patrick/Downloads/vmr.xml <<EOF
<network>
<name>vmr</name>
<forward mode='route'/>
<bridge name='virbr1' />
<ip address='192.168.198.1' netmask='255.255.255.0'>
</ip>
</network>
EOF

# make sure libvirtd is started
service libvirtd restart

# add the network
virsh net-define vmr.xml
virsh net-start vmr
virsh net-autostart vmr

Unfortunately the virsh commands fail because it seems it is not 
possible to start libvirtd and afaict virsh requires libvirtd.

Anyone have any suggestions how to make this work?

Thanks!

Regards,
Patrick
