OracleVM Manager template 2.2.0 trying change the host name

Question

Hi,
I have installed the OracleVM Manager 2.2.0 template
into an OraclVM Server 2.2.1.
Reading the OracleVM Manager 2.2.0 install
instructions "Readme_for_Media_Pack_B59146-01.txt" and doing
the installation in the interview area, I am asked
to provide the fully qualified domain name as the
name of the OracleVM Manager.
Therefore, I provided something like this.
ovmmanager.mydomain.mytopdomain
Later, when I was in the OracleMV Manager,
I noticed the following.
Correct information was written in my /etc/hosts file.
192.168.1.160 ovmmanager.mydomain.mytopdomain ovmmanager
The case seems however, that unusual information
was written to the /etc/sysconfig/network file.
HOSTNAME=ovmmanager.mydomain.mytopdomain
When I type "uname -a", the results are shown.
ovmmanager.mydomain.mytopdomain
I say, "unusual", because most people prefer a single
name "ovmmanger" to be the host name.
I have tried to permanently change the host name of the computer by
changing the contents of the /etc/sysconfig/network file to the following.
HOSTNAME=ovmmanager
Next, at the command line I would type the following.
hostname ovmmanger
When I type "uname -a", the results are shown.
ovmmanager
However, every time I do an 'xm shutdown' to the
OracleVM Manger (the ovmmanger), and then later do an
'xm create vm.cfg' to start the ovmmanger,
when I type a "uname -a", the results are shown.
ovmmanager.mydomain.mytopdomain
When I look at the contents of the /etc/sysconfig/network file
the contents are back to the original contents.
HOSTNAME=ovmmanager.mydomain.mytopdomain
instead of my preferred contents
HOSTNAME=ovmmanager
My first question is the following.
By design, does the OracleVM Manager 2.2.0 template
supposed to have a host name to be a
fully qualified domain name?
ovmmanger.mydomain.mytopdomain.
My second question is the following.
If the situation is satisfactory to have just
ovmmanger
as my host name, then how do I prevent the host name renaming
process to reoccur every time I do an 'xm create vm.cfg' to start
the OracleMV Manager?
Thank you

First Question: No, it does not have to be a full qualified hostname. As long as the hostname is resolved in your network short qualified is fine.
Second Question: You don't have to do anything. In OVM Template design the configuration tool is just called the first time your template is started. All succeeding startups will not go through the configuration again. (There is however an option to reenable/reset the VM that the configuration is called again).
