I cannot ping / ssh to any of my instances. I can associate IPs to the instances but they do not appear when ssh/ping is invoked. Im running RHEL6.4 please help. Here's my machine:

Also these series of commands do not work:

[root@xxxxxx ~(keystone_admin)]# killall dnsmasq

[root@xxxxxx ~(keystone_admin)]# service openstack-nova-network restart

[root@xxxxxx ~(keystone_admin)]# ping xx.xx.xx.xxx

PING xx.xx.xx.xxx (xx.xx.xx.xxx) 56(84) bytes of data.

From xx.xx.xx.xxx icmp_seq=2 Destination Host Unreachable

From xx.xx.xx.xxx icmp_seq=3 Destination Host Unreachable

And when I run "nova ssh Test-2" it returns:

ERROR: No public addresses found for 'Test-2'.

Even though in the Dashboard it says:

IP Addresses

Public xx.xx.xx.xx.xxx, xx.xx.xx.xx.xxx

Private xx.xx.xx.xx.xxx
