So, I've tried the latest oneiric cloud images from today and two days
ago and I still get the "PTY allocation request failed on channel 0"
connecting via ssh.

With euca-get-console-output <instance id> I still get (from nova-api.log):
(nova.api): TRACE: RemoteError: Error local variable 'fpath' referenced before assignment
(nova.api): TRACE: [u'Traceback (most recent call last):\n', u'  File "/usr/lib/pymodules/python2.7/nova/rpc.py", line 232, in _process_data\n    rval = node_func(context=ctxt, **node_args)\n', u'  File "/usr/lib/pymodules/python2.7/nova/exception.py", line 97, in wrapped\n    return f(*args, **kw)\n', u'  File "/usr/lib/pymodules/python2.7/nova/compute/manager.py", line 1023, in get_console_output\n    output = self.driver.get_console_output(instance_ref)\n', u'  File "/usr/lib/pymodules/python2.7/nova/exception.py", line 124, in wrapped\n    raise Error(str(e))\n', u"Error: local variable 'fpath' referenced before assignment\n"]

However, on the compute node I can see the correctly booted system with
'virsh -c lxc:/// console <instance-id>'
