Open Stack

Dear all,
I just finished to install Devstack as is, without any editing to the
localrc file.

If I try to create an instance (admin or demo user ) using the cirros_0.3.1
image, I receive the following error:

*Error: *Failed to launch instance "Istance_Name": Please try again later
[Error: Remote error: ProcessExecutionError Unexpected error while running
command.
Command:
sudo nova-rootwrap /etc/nova/rootwrap.conf env
CONFIG_FILE=["/etc/nova/nova.conf"]
NETWORK_ID=1 dnsmasq --strict-order --bind-interfaces --conf-file=
--pid-file=/opt/stac
].

So, I have tried to run the command:
sudo nova-rootwrap /etc/nova/rootwrap.conf env
CONFIG_FILE=["/etc/nova/nova.conf"]
NETWORK_ID=1 dnsmasq --strict-order --bind-interfaces --conf-file=
--pid-file=/opt/stac

directly in the terminal, receiveing the followinf error:

*dnsmasq failed to create listening socket for 127.0.0.1 address already in
use*

How can I resolv this problem?

Thank you!
