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
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/ubuntu-root
                       20G   14G  4.8G  74% /
tmpfs                 751M     0  751M   0% /lib/init/rw
udev                  737M   76K  737M   1% /dev
tmpfs                 751M     0  751M   0% /dev/shm
/dev/xvda1            228M   16M  201M   8% /boot

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
