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?
Yes, changing the filterref of the interface of a running domain has
been supported since v1.0.1, but you've found a genuine bug! I've
reproduced it on my system with the last sources from git, produced a
patch to fix it, and posted it to the upstream list:
http://www.redhat.com/archives/libvir-list/2014-May/msg00005.html
Once this is ACKed and pushed, I'll pull it into the maintenance
branches back to 1.0.1.
Thanks for reporting this problem!
