Hello,
Similar to the other thread about possible regression with rbd, there might be
a regression with nbd.
This time we are launching an instance from an image (not volume) and try to
live migrate it:
nova live-migration <test_instance>
The nova-compute service complains with:
2017-03-31 15:32:56.179 7806 INFO nova.virt.libvirt.driver

I will try and bisect it myself, but I thought I would paste this here first,
just so you know there is this issue too.
