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:<br>
<br>

<br>
Once this is ACKed and pushed, I'll pull it into the maintenance
branches back to 1.0.1.<br>

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:<br>
