To access remotely: Terminal → ssh root@vmserver01.student.lab → pw: bob

 1.
    aptitude install xen-linux-system-2.6.26-2-xen-686 and xen-tools
 2.
    continue: y
 3.
    command: vi/etc/modules (to add loop support module)

max_loop=255

network-script network-bridge setting in xend-config.sxp

 1.
    command: cd /etc/xen
 2.
    command: vi xend-config.sxp (uncomment: (network-script network-bridge) comment: (network-script network-dummy) (# = comment)

ensure vif-script is vif-bridge, same file

 1.
    command: cd /etc/xen
 2.
    command: vi xend-config.sxp (search for vif-script and make sure it is uncommented and accompanied with vif-bridge)

configure the grub boot entry accordingly (allow for the host to have 256MB)

 1.
    command: cd /boot/grub
 2.
    command: vi menu.lst
 3.
    Go to the bottom and remove the second and third entries (in our case).
 4.
    Go to:

title Xen 3.2-1-i386 / Debian GNU/Linux, kernel 2.6.26-2-xen-686

root (hd0,0)

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

module /boot/vmlinuz-2.6.26-2-xen-686 root=/dev/hda1 ro console=tty0

module /boot/initrd.img-2.6.26-2-xen-686

And where it says:

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

Make the adjustments specified at: http://lab46.corning-cc.edu/haas/hpc0/projects/vm_server_install

Create the following directories: /xen, /xen/images, /xen/boot, /xen/conf, /xen/save

 1.
    command: mkdir and the paths specified above

command: reboot

 1.
    network-script network-bridge setting in xend-config.sxp (uncommented in vm server install; make sure there is no space before that line)
 2.
    xen-create-image –hostname=vm07 - -mac=00:16:3E:2E:C0:07 - -role=udev - -dhcp - -force (after xen-create-image there are actually two hyphens(- - force will overwrite an existing vm as well))

log file created: /var/log/xen-tools/vm07.log

 1.
    Enter new password: bob
 2.
    verificate
 3.
    xm create -c /xen/conf/vm07.cfg
 4.
    login: root
 5.
    password: bob

detach: ^] (ctrl closing square bracket)

reattach command: xm console vm07 (hit enter again)

command: xm list (lists virtual machines; run from vmserver01)

command: xm shutdown vm# (run from vmserver01)

 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)
14.
    yes (for previous step)

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 xte 'mousemove 40 40' xte 'mousedown 1' xte 'mousemove 30 70' xte 'mousedown 1' xte 'mouseup 1' sleep 3
