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.
The patch is now pushed upstream to master and to all existing -maint branches that have the bug. There is also a bug filed against the Fedora 20 build of libvirt to track it there: https://bugzilla.redhat.com/show_bug.cgi?id=1093301 commit 0eac9d1e90fc3388030c6109aeb1f4860f108054
