[Users] hosted-engine deployment doesn't accept legal email address (ovirt-3.4.0-prerelease)

Hi, I am happily testing the hosted engine feature, sorry I was late on the test day but I dare to provide some feedback. To be more clear I prefer to report one item per email. This is related to a really minor issue I think it doesn't deserve a Bugzilla but I'm ready to do it if requested. So, during # hosted-engine --deploy in the step named "--== HOSTED ENGINE CONFIGURATION ==--" we are asked to provide a couple of email addresses but addresses with an hypen before the @ sign (ex. my-name(a)mydomain.com ) aren't allowed and throwns the following: [ ERROR ] Invalid input, please try again As a workaround I used another address but, looking at /usr/share/ovirt-hosted-engine-setup/plugins/ovirt-hosted-engine-setup/ha/ha_notifications.py (ovirt-hosted-engine-setup-1.1.0-0.5.beta2.el6.noarch) I've found that _RE_EMAIL_ADDRESS is using a simplified pattern (hope that gmail doesn't mangles text too much): [a-zA-Z0-9_.+]+ @ [a-z0-9.-]+ even avoiding the intricacy of the whole possibilities (see "Local part" in http://en.wikipedia.org/wiki/Email_address ) I think the following (not tested) could be more appropriate: [a-zA-Z0-9] [a-zA-Z0-9_.+-]+ [a-zA-Z0-9] @ [a-z0-9.-]+ don't know if it really works as I've never programmed in python but I hope you get the idea. Best regards, Giorgio.
