Description Marina Kalinin 2018-07-02 03:09:32 UTC
RHV should have end to end VNC encryption for accessing its VMs via VNC.

It is possible to enable tls in qemu vnc server[1], but RHV does not use it and does not expose this option to the user via RHV portals.

How this request should be implemented:
- Provide "Enable TLS" option for VM console when VNC is chosen.
- If "Enable TLS" is selected, once VNC connection is established, it should be encrypted end to end, from client to the host.

Re-targeting to 4.3.1 since it is missing a patch, an acked blocker flag, or both

Verified on:

1. Add a new cluster / Change existing cluster to VNC encrypted.
2. Install a host in the cluster, check vnc_tls=1 in the /etc/libvirt/qemu.conf file.
3. Create a VM in the cluster.
4. Edit the VM to VNC console.
5. Start the VM.
6. Invoke a console to the VM.

Using tigerVNC, a connection is established and it is encrypted.
