+++ This bug was initially created as a clone of Bug #978665 +++
The default ports for accessing RHEVM in version 3.0 was 8080/8443, which has been changed to 80/443 in version 3.1 and higher. When upgrading an environment from 3.0 to 3.1, the default ports have to be manually set in the httpd and ovirt-engine conf files, and the firewall rules have to be updated to accept ports 80/443.
Upgrading to Red Hat Enterprise Virtualization Manager 3.1 
Present in Install and Admin Guide.
Does not apply to future upgrade topics.
(Note: To check with PM if we will continue to support upgrade from 3.0->3.1 in v3.3 of the guides. If not, close this bug.)
