[D] VNC console on edge host [cloudstack]

GitHub user cdfgallo created a discussion: VNC console on edge host

Hi all,

I'm trying to figure out how to manage VNC connections to egde host's VMs.
I see that the connection is using vencrypt but I'm getting errors with every client I try to use and I didn't found out how to disable encryption. What client do you use and how you configure it?

Thank you!

If the vm is running, you can get the vnc password on kvm host
```
virsh dumpxml --security-info <instance name> |grep vnc
```

you can try the following
- set vnc_tls to 0 in /etc/libvirt/qemu.conf
- restart libvirt/lbivirtd
- stop/start the vm instances

Hi @weizhouapache,
after a few I was able to bypass the encryption but I'm now stuck as I'm not understanding how to retrieve the VNC password for a VM. I see that are encrypted in the database but I can't find a way to decrypt them following the docs (https://docs.cloudstack.apache.org/en/latest/installguide/encryption.html) and looks like the VNC default password implemented on libvirt configuration is not used.
Thank you!
