[libvirt-users] virsh update-device: need to clear network filters

Hi, Can anyone please help with the following: I have a running instance with interface <interface type='bridge'> <mac address='fa:16:3e:ba:a4:67'/> <source bridge='br100/> <target dev='vnet0'/> <model type='virtio'/> <filterref filter='nova-instance-instance-00000001-fa163ebaa467'/> <alias name='net0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> what I need is to clear network interface on the instance. I tried virsh update-device with following xml: <interface type='bridge'> <mac address='fa:16:3e:ba:a4:67'/> <source bridge='br100/> <model type='virtio'/> </interface> but this results in the following error: $ sudo virsh update-device 13 xml.xml --persistent --live --config error: Failed to update device from xml.xml error: End of file while reading data: Input/output error error: Failed to reconnect to the hypervisor and libvirt is restarted. Is it possible to clear nw filter at all? Thanks, Oleg
