Title:
As I said this is hard to test explicitly.
The issue is between instantiating and destroying nwfilters.
So to stress the area of the code I created a test:
1. run a guest (bionic in my case, but it doesn't matter)
2. prep hotpluggable interfaces with deep nwfilter rules

Hello Pooja, or anyone else affected,
Accepted libvirt into xenial-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/libvirt/1.3.1-1ubuntu10.21 in a few
hours, and then in the -proposed repository.
Please help us by testing this new package. See

mentioned in the SRU Template it is inherently racy and so far never
triggered for me. So this isn't a full verification, but more a sanity
check.

Fix checked by regressions tests against ppa, ready for SRU considerarion.

As initially reported it "intermittently" fails.
That will make the SRU template a bit thin on test steps.
Never the less the fix is correct and makes sense.

Thanks Christian!
Right, we were building libvirt from upstream 1.3.5 source code for
ubuntu14 earlier, however that same build procedure didn't seem to work
for ubuntu16. Hence the need for backporting it to xenial/trusty, so
that we can use the libvirt packages available from ubuntu repo
directl
Thanks for the report Pooja,
this is fixed in v1.3.5
By that this in anything newer than Xenial via being upstream.
I need to take a look at backporting the suggested change to Xenial, but
that will probably not happen this week as I'm traveling.
