Sure. Perhaps there is something we need to change from older versions (perhaps cronjobs?), but specifically the message queue tasks don't seem to work with openstack. When the szrmessaging task runs:
/usr/local/scalr/current/cron/cron.php --SzrMessaging
We have the following errors:
2013-04-27 19:55:19,345 - ERROR [tran517c2cd9bde87:Logger@628] - 'Cannot handle message \'Hello\' (message_id: 883b1ebe-dfe5-4561-aa55-573b1dedaf82) from server \'172.20.0.143\' (server_id: a7e47af1-85c0-4b76-8663-9d71e3aa1a7b).

We tracked it down, and all of the variables are attempting to be pulled from server_properties, while they appear to have been moved to a hashed table called client_environment_properties. Perhaps there are changes needed to scripts used in 4.1?
