Struggling with vnc and virt-install [closed]

As an exercise, I'm working to create a CentOS 7.0 guest image for use on an Openstack cluster.

Because of permissions and NFS mounts and such, I'm unable to use the virt-manager GUI console, but I can use virt-install and virsh to see my hosts.

I'm trying to use the example described here: (

The host starts up, and shows running with virsh list

Here's my virt-install command:

virt-install --virt-type=kvm --name=CentOS-7.0-1406-mojo --ram=1024 \
--cdrom=CentOS-7.0-1406-x86_64-DVD.iso \
--disk CentOS-7.0-1406-mojo.qcow2,format=qcow2 \
--network network=default \
--graphics vnc,listen= --noautoconsole \
--os-type=linux --os-variant=rhel7

So now the example page says: "In the example above, the guest centos-6.4 uses VNC display :1, which corresponds to tcp port 5901. You should be able to connect to a VNC client running on your local machine to display :1 on the remote machine and step through the installation process."

When I start vncviewer on my host machine, I prompts for the VNC Server specification, and the Encryption. I'm not sure what to use. localhost doesn't work. (the IP gateway for the default network) doesn't work. :1 doesn't work.

If I use, it prompts me for a username and a password, which I don't know (there's no authentication on the vnc server). If I specify it gives a warning about being unencrypted, and then vncviewer terminates abruptly.

Can someone add some clarity to how to connect to the guest VNC server?
