Hi Dimitri,

>From a dashboard perspective, the "Confirm resize" button is only
displayed when the instance status gets to the final "VERIFY_RESIZE"
stage. Out of curiosity, does the confirm resize command works on the
stuck instances from the CLI? ("nova resize-confirm <server_id>")

I'm not familiar enough with Nova to be able to provide additional
information on why the instances might be getting stuck, unfortunately,
hopefully someone else can offer more insightful advice.
