    *
      kernel /boot/xen-3.2-1-i386.gz

Add at the end of line: dom0_mem=262144 For this to take affect, reboot.

configure Xen-tools (/etc/xen-tools/xen-tools.conf) with some useful defaults:

   1.
      command: cd /etc/xen-tools/
   2.
      vi xen-tools.conf

==== data and storage the right way ====

   1.
      from vmserver01 → command: xm shutdown vm09
   2.
      xm list to verificate
   3.
      command: cd /xen/domains/vm09
   4.
      command: dd if=/dev/zero of=disk1.img bs=1M count=1024
   5.
      repeat previous step 5 times BUT replacing disk with an incremented count up to 5
   6.
      mkfs.ext3 -v disk1.img (formats disk)
   7.
      proceed (for previous step)
   8.
      cd /xen/conf
   9.
      vi vm09.cfg
  10.
      copy/paste the line with 'file:/xen/domains/vm09/disk.img,xvda2,w', 5 times and put int the count of numbers after disk as well as after xvda
  11.
      xm create -c /xen/conf/vm09.cfg (- -force if overwriting an existing vm)
  12.
      aptitude search mdadm
  13.
      aptitude install mdadm (if discovered via the search from the previous step, this one can be skipped)

==== autodrawing for fashon and awesomenessification ====

because i am a great i know this is how you bring up x-paint and resizes and moves everything to its proper place

#!/bin/bash

#screen awareness
maxX=`xwininfo -root | grep Width | cut -d" " -f4`
maxY=`xwininfo -root | grep Height | cut -d" " -f4`

pkill xpaint
sleep 2

let x=$maxX-135 #124 is the width of the xpaint tool panel

xpaint -size "$x"x"$maxY" &
sleep 3

winId=`xwit -print -all | grep -i xpaint | cut -d":" -f1`
toolBoxSize=`xwininfo -id $winId | grep Width | cut -d" " -f4` #This will get the width of the toolbox for xpaint
let canvasSize=$maxX-$toolBoxSize                                                        #This will find the max width of the canvas
sleep 3

xwit -id $winId -move 0 0
sleep 4

#open new canvas
