[fedora-virt] F-12 host, can't acquire DHCP lease in guest

[Andrew Overholt]

Hi,

I installed rawhide/F-12 x86_64 (network using NetworkManager) and installed
and started libvirtd.  I then created both F-12 i686 and F-11 i686 guests which
went fine.  However, neither guest is able to acquire a DHCP lease.

Is there some sort of configuration that I didn't do?  I don't recall having to
do anything special with F-11 as a host.  Relevant information below.

I can file a bug if that's preferred.

Thanks,

Andrew

I've reloaded the libvirtd service, restarted it, rebooted the guests, etc.
