Sorry about the delay.

Code:
echo "password" | sudo -S -su weblogic

-S makes sudo "read the password from stdin", and this is what it means; it takes input from its standard input, to which you can redirect the output of something else, like echo printing out the actual password.
Again, make sure your script is only readable by the concerned users, because anyone who can cat it will see the password.

NAME
fence_virsh - Fence agent for virsh DESCRIPTION
fence_virsh is an I/O Fencing agent which can be used with the virtual machines managed by libvirt. It logs via ssh to a dom0 and there run virsh command, which does all work. By default, virsh needs root account to do properly work. So you must allow ssh login in your sshd_config. fence_virsh accepts options on the command line as well as from stdin. Fenced sends parameters through stdin when it execs the agent. fence_virsh can be run by itself with command line options. This is useful for testing and for turning outlets on or off from scripts.
