Sorry I didn't attach that immediately. The error shows clearly in
the log. As do some others. Though I'm not sure what's missing that
causes that python error.

vdscli raised when hosted-engine-setup called getVdsCapabilities()

The issue is probably here where VDSM try to respond with a None value for the host UUID
'vmTypes': ['kvm'], 'selinux': {'mode': '1'}, 'liveSnapshot':
'true', 'kdumpStatus': 0, 'networks': {}, 'bridges': {}, 'uuid':
None, 'onlineCpus':

Indeed you had:
Thread-64::DEBUG::2015-08-31
12:33:15,127::utils::661::root::(execCmd) /usr/bin/sudo -n
/usr/sbin/dmidecode -s system-uuid (cwd None)
Thread-64::DEBUG::2015-08-31

12:33:15,154::utils::812::root::(getHostUUID) Could not find host UUID.
Thread-64::DEBUG::2015-08-31

Can you please try executing?
/usr/sbin/dmidecode -s system-uuid
