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
Hello,
Just redefine specified filter at the runtime, ebtables rules should get
updated accordingly. I`ve used to do the same in my product more than a
year ago and can confirm that it worked fine.
