Comment 27 for bug 1688508

After some debugging I found why it isn't correctly iterating anymore.

Note Local Branch: fix-lp1688508-guestscoping

Submitted to upstream as: https://www.redhat.com/archives/libvir-list/2018-March/msg01068.html

P.S. It wasn't even our fix that broke it, we just made it get further and then break on this under certain conditions (more guests than parallel) - it always had the chance to break that way.

Once accepted upstream we can add it in Bionic and from there reconsider a better SRU.
