I notice port 5900 is not opened in iptables on the compute-nodes. should it be opened to accept vnc request?
We need more information of environment to correctly handle your problem but about your question it seems not necessary to open port 5900. Please refer yourself to: http://docs.openstack.org/kilo/config-reference/content/list-of-compute-config-options.html (vnc section) and https://access.redhat.com/documentation/en/red-hat-enterprise-linux-openstack-platform/version-7/red-hat-enterprise-linux-openstack-platform-7-installation-reference/chapter-8-install-the-compute-service
