====== creating Ubuntu based VM Template ======
Mainly you will need to create Ubuntu VM manually and then do the following steps to the template before converting it to Template
- create new Ubuntu vm and while installing it make sure you do the following steps
* 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
so that after you are done installing the following when you do lvdisplay
lvdisplay
--- Logical volume ---
LV Name /dev/ubuntu/root
VG Name ubuntu
LV UUID FRarW6-pk6o-BibE-dkIy-3c8O-U1l9-en27mC
LV Write Access read/write
LV Status available
# open 1
LV Size 19.39 GiB
Current LE 4964
Segments 2
Allocation inherit
Read ahead sectors auto
- currently set to 256
Block device 254:0
--- Logical volume ---
LV Name /dev/ubuntu/swap_1
VG Name ubuntu
LV UUID s4PNXH-vtLx-U09C-Ggzn-2wg6-vbFC-qReidn
LV Write Access read/write
LV Status available
# open 1
LV Size 376.00 MiB
Current LE 94
Segments 1
Allocation inherit
Read ahead sectors auto
- currently set to 256
Block device 254:1
and df output is
df -h

/dev/mapper/ubuntu-root

udev 737M 76K 737M 1% /dev

__Note:__ the sizes are not important
* **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 [[HERE]]) and put inside /etc/
so that you will have the file locations as follows
/etc/xenicastart.sh
assign the executable mode to the file by the command
chmod +x /etc/xenicastart.sh
Open the file /etc/rc.local in edit mode and put the line
/etc/xenicastart.sh
inside /etc/rc.local
* now make sure xentools installed
* install in the vm parted package
apt-get install parted
* do fdisk -ul and write down the number you get in this section
fdisk -ul
dev/xvda1 * 2048 499711 248832 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/xvda2 501758 16775167 8136705 5 Extended
in my case it was 16775167 (the end of /dev/xvda2 partition)
* now open the script at /etc/xenicastart.sh and edit the line
(echo n; echo p; echo 3; echo 16775168; echo ; echo t; echo 3; echo 8e; echo w) | fdisk -u /dev/xvda
to the number you got in step 5 +1
* convert to template
