[Bug 1310340] Re: live migration fails when use long hostname of a nova compute target host

[Adam Spiers]

Hi Melanie, just wondering why this change was abandoned?  Unless I
misunderstood, it seemed that the only objections to Patch Set 4 were
regarding implementation details, not against the approach.  Your way of
guarding against accidentally using the wrong non-unique hypervisor host
seems good to me, but maybe I'm missing something?  Thanks!

  nova live-migration ubuntu14.04  compute2.site.local
  ERROR (BadRequest): Compute service of  compute2.site.local is unavailable at this time. (HTTP 400) (Request-ID: req-f344c0bf-aaa3-47e6-a24c-8f37e89858e4)

  but 
  nova live-migration ubuntu14.04  compute2
  runs without error 

  
  Also if you try to do migration through horizon it always fails because horizon use long hostname fo target host.
