The root cause was found to be at the compute node (10.52.224.20) which dropped network connection on vnc-server port(s) (i.e. 5900+N) from the controller node. 22: connecting to: 10.52.224.20:5903 22: handler exception: [Errno 113] EHOSTUNREACH A temp work-around is to manually open up vnc ports on compute node(s). -A INPUT -m state --state NEW -m tcp -p tcp --dport 5900:5950 -j ACCEPT Wondering if this could be addressed dynamically, during VM creation ideally. The issue was found with openstack-nova-compute-2013.2-2.el6 running on CentOS kernel 2.6.32-358.123.2.openstack.el6.x86_64.
