Creating a linux image on the server homework


Hello all,

I have been editing this script my teacher provided me. I have been getting errors after I ran the script to an image on the server.

here is the script:
#!/bin/bash
GUESTIMAGESTORAGE=/home/wahab/Desktop/linux
GUESTIMAGEFORMAT=qcow2
ISOSTORAGE=/home/wahab/Desktop/iso
ISOFILENAME=SL-63-x86_64-2012-08-02-Install-DVD.iso
NETWORKBRIDGE=guest_os_bridge
KICKSTARTFILEPATH=/home/wahab/Desktop/kickstart
GUESTRAM=1024
GUESTDISKSIZE=4

GUESTNAME64=sl63x86_64_wgul
KICKSTARTFILENAME64=sl63x86_64_ks_base.cfg
KICKSTARTFILELOCATION64=$KICKSTARTFILEPATH/$KICKSTARTFILENAME64
echo "$KICKSTARTFILELOCATION64"
# Create images directory

hi there
first you might want to use the "code" tags when posting
PHP Code:

using chmod with "777" on system files is likely to cause the operating system to not boot

or if folders in your home like "Desktop"
you might not even be able to login as that user

most OS's check if the "system files" have the correct permissions and if NOT then NOT BOOT
this is a safety precaution

and SELinux REALLY checks things ,and if the SE context is not correct it will not run

also this

linux is not Windows
the "Desktop" folder is a special case folder
keeping programs there can cause problems , like they might not work

"sl63x86_64"
so this is ScientificLinux 6.3 you have
SELinux can also cause problems if you use the "Desktop" folder

-- linux is not windows --
so please do not try to fill up the "desktop " with 1,000+ "installers"

there should be a folder in your home folder called "public"
that is in the system $PATH for your normal user

thank you very much for your help. I have moved the data from Desktop to Public folder. I am still getting this error.

being "homework"

you might want to re go over the section in your textbook
paragraph by paragraph to look for what you missed on moving a VM image from one VM to another
