General Upgrade Notes
=====================


Depreciation of realhostip.com 
------------------------------
   
The realhostip.com dynamic DNS resolution service is being retired on
September 30th, 2014. In advance of that, CloudStack 4.4 and later no longer uses 
realhostip.com DNS domains or SSL certificates to encrypt Console Proxy or 
file copy communications.

For latest update about realhostip.com follow `Apache CloudStack Blog <https://blogs.apache.org/cloudstack/>`_.



Settings Changes
----------------

Console Proxy URL
^^^^^^^^^^^^^^^^^

Please use ***.realhostip.com** (note the asterisk) as
``consoleproxy.url.domain`` value in global configs if you are using HTTPS for
console proxy. Please note that you need to restart the management server when you change
the global config value.

If you started with 4.3, you are likely running the console in HTTP mode
and the value of the above global config should be blank.

If switching between HTTP / HTTPS, the console proxy VM has to be
destroyed and recreated (available via UI)


Cluster Settings
^^^^^^^^^^^^^^^^

After upgrading to 4.2 and later, Settings ``mem.overporvisioning.factor`` and 
``cpu.overporvisioning.factor`` are now at the cluster level and be set to 1 
which is the default.

If Global Settings ``mem.overporvisioning.factor`` and 
``cpu.overporvisioning.factor`` have been changed prior the upgrade to 4.2 and 
later, the upgrade process will be reset them to 1. Values can be changed by 
editing clusters settings.

All clusters created after the upgrade will get created with the Global Settings 
values for ``mem.overporvisioning.factor`` and ``cpu.overporvisioning.factor``.
