Comment 4 for bug 1577809

i've reproduced the same error. my steps were:

new centos 7 install on my virt host

sudo yum -y update
git clone https://git.openstack.org/openstack/tripleo-quickstart
cd tripleo-quickstart/
sudo bash quickstart.sh --install-deps
bash quickstart.sh --config config/general_config/devmode.yml --release master-tripleo localhost

This fails with:
TASK [setup/overcloud : Define volume pool] ************************************
task path: /home/jslagle/tripleo-quickstart/roles/libvirt/setup/overcloud/tasks/main.yml:27

I assume using localhost for $VIRTHOST should be ok?
