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

[marvel]

Yes, I met this problem, horizon give me nodes like "node1.expr", while
the database has only "node1", causing live migration failure, a little
fix is listed below:

 50     def populate_host_choices(self, request, initial):
 51         hosts = initial.get('hosts')
 52         current_host = initial.get('current_host')
 53         +host_list = [(host.service['host'],
 54         +              host.service['host'])
 55         +             for host in hosts
 56         +             if host.service['host'] != current_host]
 57         -host_list = [(host.hypervisor_hostname,
 58         -              host.hypervisor_hostname)
 59         -             for host in hosts
 60         -             if host.service['host'] != current_host]
 61         if host_list:
 62             host_list.insert(0, ("", _("Select a new host")))
