====== creating CentOS based VM Template ======

Mainly you will need to create Centos VM manually and then do the following steps to the template before converting it to Template

  - create new CentOS vm and while installing it make sure you do the following steps(actually default centos install will be having those 2 properties)
     * make the boot partition is separate from other partitions (you can choose any file system for it)
     * remaining partitions should be lvm based storage be on lvm based storage<code>
    so that after you are done installing the following when you do lvdisplay
lvdisplay
  --- Logical volume ---
  LV Path                /dev/VolGroup/lv_root
  LV Name                lv_root
  VG Name                VolGroup
  LV UUID                aaVIJ1-EmVY-vjCG-Y6bH-1FaC-nUYk-IPrF6V
  LV Write Access        read/write
  LV Creation host, time localhost.localdomain, 2014-05-13 22:28:44 -0400
  LV Status              available
  # open                 1
  LV Size                6.71 GiB
  Current LE             1718
  Segments               1
  Allocation             inherit
  Read ahead sectors     auto
  - currently set to     256
  Block device           253:0
   
  --- Logical volume ---
  LV Path                /dev/VolGroup/lv_swap

</code>and df output is <code>
df -h

  * **now we need to make scripts run automatically on system startup ,** 
get the script file: xenicastart.sh from your xenica package (or you can get it from [[http://wiki.servarica.com/centos7/xenicastart.sh|here]]) , and put inside /etc/
so that you will have the file locations as follows
<code>/etc/xenicastart.sh</code>
  - assign the executable mode to the file by the command<code>
chmod +x /etc/xenicastart.sh</code>
  - To make the script run at the start of the VM:
  -    Open the file /etc/rc.local in edit mode
  -    put the line <code>source /etc/xenicastart.sh</code> inside /etc/rc.local
  -    run this script as /etc/rc.local on the command line to make sure it executes our script
  - make sure xentools installed
  - install in the vm parted package <code>yum install parted</code>
  - convert to template
