Last thing I saw is "#/bin/bash" instead of "#!/bin/bash". Fix and try.
The rest of suggestions:
Add plenty of unique "echo" lines so you can see where it brakes.
Also try $(`virsh list | grep -v -e Id -e --- -e Domain-0 | awk '{print
$1}'`)
and try sending that same part to variable first and echo the variable
so you can see output.
#!/bin/bash
list=$(virsh list | grep -v -e Id -e --- -e Domain-0 | awk '{print $1}')
echo "the list is=$list"; sleep 2
for i in "$list";
do
echo "Running shutdown for item $i"; sleep 2
/usr/bin/virsh shutdown $i
echo " shutdown for item $i is complete"; sleep 2
done
and try version with:
list=$(`virsh list | grep -v -e Id -e --- -e Domain-0 | awk '{print $1}'`)
