[libvirt-users] 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
