Install DevStack on Ubuntu 12.04 LTS Precise: hangs when running stack.sh script

The script hangs on the following line:

instances=`sudo virsh list --all | grep $INSTANCE_NAME_PREFIX | sed "s/.*\($INSTANCE_NAME_PREFIX[0-9a-fA-F]*\).*/\1/g"`

Solution

• Open a new terminal window, run the following command:

  sudo killall -9 dmidecode
