libvirt users - May 2010 - Hot-add interface crashes libvirt

Hi Everyone,
   After upgrading FC12 and now FC13 whenever I try to attach a network device
using attach-device it promptly crashes libvirtd.  Is there an option that
changed in the network interface xml spec I missed?
   I really need this feature or at least the ability to connect and disconnect
interfaces if that's possible?

I've tried defining my network card in several ways:

First the one that worked previously:

<interface type="network">
   <mac address="52:54:00:5c:fe:a8"/>
   <source network="fedora"/>
</interface> 

Second copying what appeared in the xml after using the add hardware through the
VMM:


<interface type='network'>
   <mac address='52:54:00:5c:fe:a8'/>
   <source network='fedora'/>
   <address type='pci' domain='0x0000' bus='0x00'
slot='0x06' function='0x0'/>
</interface> 

Both ways fail now. Please help.
Thanks,
Steve

This should work with virsh attach-device $VMNAME $XMLFILE. I can't seem
to reproduce this issue on F12 though. Can you capture the libvirtd crash?

- debuginfo-install libvirt
- service libvirtd stop
- gdb libvirtd, at the prompt type 'run'
- In another terminal, reproduce the crash
- In gdb, type 'thread apply all bt'

Post that output here, along with all your libvirt and qemu versions,
and what steps you took to reproduce.

Manually specifying the <address> piece shouldn't be required, libvirt
will autogenerate it for you.
