I wonder if that is too aggressive and is causing issues with operations where the guest is stopped and started, though for resize/migrate/shelve/unshelve the guest is destroyed on one host and re-spawned on another, so I would think that having a graceful shutdown for the guest wouldn't matter in those cases, unless it has to do with leaving the guest "dirty" somehow before transferring the root disk / creating a snapshot (in the case of shelve). Maybe we should bump that back up to 10 seconds?

I finally spent some time on investigating this issue. I was able to reproduce it locally and I found that the problem is in openvswitch firewall. All is described in [1]. I just pushed patch which should fix this. It’s in [2].
