The Citrix XenServer CI is failing on most, if not all, changes it's running on today. Here is an example failure [1]. Devstack fails to setup due to a bad package install, so I'm guessing there is a problem in a mirror being used. I don't know if this is 100% failure but it's high enough to disable it from voting on new nova patch sets. If you hit this, simply comment on your patch with 'recheck'.
