# Author: Murray Saul
# Date: January 17, 2015
#
# Purpose: To allow a Linux sysadmin to identify status of
# VMs on system and stop them...
# Check to see if logged in as root to be able to create file
# in /root/ directory...
if [ $USER != "root" ]
then
echo "You must be logged in as root to run the command."
echo "Either login as root or issue command \"sudo ./report1.bash\""
exit 1

# Create dummy virsh list file (virsh list --all) for testing purposes
# to incoporate the zenity command to list status of VMs and
# use checkbox to check or uncheck based on their status in order
# to launch VM that are only "shut-off"
