Cannot connect to Openstack Instance via horizon, but SSH works?
Solution 1
I think your URL reference should be your public IP.
novncproxy_base_url=http://:6080/vnc_auto.html
xvpvncproxy_base_url=http://:6081/console
Try that.
Solution 2
Try this on the compute node you want to access from NoVNC
iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 5900:5950 -j ACCEPT
iptables -D INPUT -j REJECT --reject-with icmp-host-prohibited
If this is the right solution save it
iptables-save
Hope you can find the solution. Regards Gerardo
Solution 3
Put --vncserver_listen=0.0.0.0
instated of --vncserver_listen=172.16.0.1
in your configuration. Restart relevant services then try to access the instance via VNC.
It should work.

I've got an OpenStack deployment running inside a VM for testing purposes. My setup is as follows: Host Ubuntu x64 with Virtualbox -> Guest Ubuntu x64 with OpenStack -> Ubuntu X64 Server Test Instances through Openstack.
I realize it is of no practical use, but as said, it is for testing purposes only. I successfully launched an instance, binding it to 11.1.0.3 and 172.16.1.1 (host is 172.16.0.1) and I can successfully ssh into it from either the host or the guest VM with
ssh -i key.pem [email protected]
(or172.16.1.1
). Unfortunately, the NoVNC via Horizon does not work (Starting VNC handshake -> Failed to connect).The relevant lines from my nova.conf are the following:
--novnc_enabled=true --novncproxy_base_url=http://172.16.0.1:6080/vnc_auto.html --vncserver_proxyclient_address=172.16.0.1 --vncserver_listen=172.16.0.1
So I'm not sure what's going wrong. The keypair that matches the .pem file I ssh with is of course coupled with the instance, and the instance is Active and Running.
Any help would be greatly appreciated.
Edit:
nova get-vnc-console [id] novnc
correctly supplies me with a link to vnc into the vm, but it also fails to connect.Edit 2: To clarify: I have an active, running instance that successfully launched through the OpenStack dashboard. I can ping the instance, I can ssh into it (using
'ssh -i key.pem ip
), but I cannot access it through VNC (specifically novnc on the dashboard). Trying to access the VM through the URL nova supplies through get-vnc-console does not work either. What I wish to do is access this instance via VNC.-

user16818402 about 11 yearsSorry if it was a little unclear: I added clarification as to what I meant. I wish to access the instance via VNC, but cannot as of right now.

user16818402 about 11 yearsCould you elaborate on that slightly? In my nova.conf above, I have:
--novncproxy_base_url=http://172.16.0.1:6080/vnc_auto.html
, with 172.16.0.1 being the VM's (= the system running Openstack services) public IP address as far as it is concerned. Am I missing something?
