Description

I have Foreman 1.13.2 running on CentOS 7.3 which I normally access via Google Chrome 55 on OSX 10.12.2.

Everything seems to be OK apart from the VNC Console functionality to VMware ESXi 6.5 host. When trying to connect I get "Failed to connect to server" error.

It worked fine with ESXi 6.0u2. I'm not sure what changed but it no longer works with the newest version of ESXi.

I have Foreman's CA cert added to Keychain.

VNC rule is enabled in ESXi's firewall:

[root@esxi01:~] cat /etc/vmware/firewall/vnc.xml
<ConfigRoot>
<service id='0032'>
 <id>VNC</id>
 <rule id = '0000'>
  <direction>inbound</direction>
  <protocol>tcp</protocol>
  <porttype>dst</porttype>
  <port>
   <begin>5901</begin>
   <end>5964</end>
  </port>
 </rule>
 <enabled>true</enabled>
</service>
</ConfigRoot>

[root@esxi01:~] esxcli network firewall ruleset list | grep VNC
VNC                          true

Not sure if it helps, but here's the log from the Developer Console in Chrome:

I can't see any errors in the production.log.

Here's the snippet from the log straight after pressing the Console button:

Do you still want me to enable debug logging?

Hello
I can confirm we have the same issue with our new ESXi 6.5 environments.

Actually Foreman manages to set the vnc settings to the VMs:
RemoteDisplay.vnc.port: 59xx
RemoteDisplay.vnc.enabled: true
RemoteDisplay.vnc.password: xxxxx

But then we realise that the setting is not taken into account, but it works if we reboot the VM.
After a reboot we are able to setup a VNC connection to the previous opened port

So I don't know if vmware has some kind of signal to 'reload' the console settings that we could use, or if updating these settings live is not done anymore by vmware.

Can confirm on Foreman 1.14.1 and esx 6.5.0.

I guess, the correct "fix" for this would be do ditch the VNC console altogether. VMWare has a webmks framework to get similar functionality as in their vSphere client. ManageIQ has already adapter this. [1]

I'll try to come up with a implementation for Foreman.
