    Getting errors when running test/systemvm/test_update_config.py.
    
            from envassert import file, process, package, user, group, port, cron, detect,
ip
        ImportError: cannot import name ip
    
    Got other errors when setting up devcloud by following https://cwiki.apache.org/confluence/display/CLOUDSTACK/devcloud-kvm
but I managed to work around it.
    
        Exception Occurred Under createLogs :['Traceback (most recent call last):\n', '  File
"/usr/local/lib/python2.7/site-packages/Marvin-4.6.0_SNAPSHOT-py2.7.egg/marvin/marvinLog.py",
line 157, in createLogs\n    (\'LogFolderPath\' in log_cfg.__dict__.keys()) and\n', "Attri
        buteError: 'list' object has no attribute '__dict__'\n"]

> CsDhcp.process() appends new entries to /etc/dhcphosts.txt causing duplicates like:
> {code}
> 06:49:14:00:00:4d,10.7.32.107,node1,infinite
> 06:42:b0:00:00:3a,10.7.32.107,node2,infinite
> {code}
> This makes dnsmasq fail with "no address available".
> CsDhcp.process() should repopulate the file to remove old entries with the same IP address.
