[Engine-devel] Updating ovirt engine from 3.0 to the 3.1.0 version

[Shu Ming]

Hi,
   I built a set of ovirt engine RPM packages from near the latest ovirt 
engine source code.  However, when I try to access the engine server 
with URL "http://ovirt-engine-112:80", the browser displayed a blank 
page without http error returned.  Any clue about what is going on here? 
Why didn't the engine administrator home page be shown?


And the packages were also installed successfully in my target system, 
checked this by "rpm -q -a|grep engine".
  I) upgraded the packages to the 3.1

[root at ovirt-engine-112 ~]# rpm -q -a |grep engine
ovirt-engine-restapi-3.1.0_0001-1.8.fc16.x86_64
ovirt-engine-dbscripts-3.1.0_0001-1.8.fc16.x86_64
ovirt-engine-log-collector-3.0.0_0001-1.6.fc16.x86_64
ovirt-engine-genericapi-3.1.0_0001-1.8.fc16.x86_64
ovirt-engine-backend-3.1.0_0001-1.8.fc16.x86_64
ovirt-engine-setup-3.1.0_0001-1.8.fc16.x86_64
ovirt-engine-jbossas-1.2-2.fc16.x86_64
ovirt-engine-jboss-deps-3.1.0_0001-1.8.fc16.x86_64
ovirt-engine-config-3.1.0_0001-1.8.fc16.x86_64
ovirt-engine-3.1.0_0001-1.8.fc16.x86_64
ovirt-engine-webadmin-portal-3.1.0_0001-1.8.fc16.x86_64
ovirt-engine-userportal-3.1.0_0001-1.8.fc16.x86_64
ovirt-engine-tools-common-3.1.0_0001-1.8.fc16.x86_64
ovirt-engine-image-uploader-3.1.0_0001-1.8.fc16.x86_64
ovirt-engine-notification-service-3.1.0_0001-1.8.fc16.x86_64
ovirt-engine-iso-uploader-3.1.0_0001-1.8.fc16.x86_64
gtk2-engines-2.20.2-2.fc15.x86_64

Step II)
    Then I used "engine-setup" to setup the engine.  It seems that 
everything is ok, see the log below.

-------------
[root at ovirt-engine-112 ~]# engine-setup
Welcome to oVirt Engine setup utility
HTTP Port  [80] :
HTTPS Port  [443] :
Host fully qualified domain name, note that this name should be fully 
resolvable  [ovirt-engine-112] :
ERROR: domain is not a valid domain name
User input failed validation, do you still wish to use it? (yes|no): yes
Password for Administrator (admin at internal) :
Warning: Weak Password.
Confirm password :
Organization Name for the Certificate: cstl

Should the installer configure NFS share on this server to be used as an 
ISO Domain? ['yes'| 'no']  [yes] :

Firewall ports need to be opened.
You can let the installer configure iptables automatically overriding 
the current configuration. The old configuration will be backed up.
Alternately you can configure the firewall later using an example 
iptables file found under /usr/share/ovirt-engine/conf/iptables.example
Configure iptables ? ['yes'| 'no']: yes

oVirt Engine will be installed using the following configuration:
