fix for ubuntu with xen network bridge with aliases.

[persuader]

the script coulnd get all the ip addresses of the server interfaces when running xen dom0.
ifconfig does not show aliases for the bridge interface xenbr0 so server blocks his own ip-s.

i changed the line

SERVER_IP_LIST=ifconfig | grep "inet " | awk '{print $2}' | sed "s/addr://g" | xargs | sed -e 's/ /|/g'

to
SERVER_IP_LIST=( hostname -I ; echo 127.0.0.1 ) | cat | sed ':a;N;$!ba;s/\n/ /g' | sed 's/[[:space:]]\{1,\}/|/g' | sed s'/.$//'

Now everything works as expected.

Keep up the good work.
