I have a simple setup. One machine is a node. I installed 3.6 sixth beta release node iso on a machine. IP adress is setup. Then I try to deploy hosted engine over ssh. I input a local http url of the centos 7 iso and hit Deploy. The tui stops and I get: login as: admin admin(a)192.168.100.70's password: Last login: Tue Sep 22 15:25:43 2015 An error appeared in the UI: AttributeError("'TransactionProgressDialog' object has no attribute 'event'",) Press ENTER to logout ... or enter 's' to drop to shell The iso file does exist and is working.
