Secure KVM VNC Console Access Using the CA Framework by nvazquez · Pull Request #7015 · apache/cloudstack

nvazquez · 2022-12-22T04:28:05Z

Description

This PR allows securing the console access through CloudStack to the virtual machines running on KVM. The secure access is achieved through the generated certificates for the CA Framework in CloudStack, that provides mutual TLS connections between agents. These certificates are used to also secure the connection between the console proxies and the VNC ports for VM console access.

This feature is only supported on the KVM hypervisor

not a big issue, just need to pay a bit more attention

LGTM, tested this in an old env which is upgraded to this feature. The old VM (ssvm, cpvm, VR etc) had unencrypted vnc console; on stop/start they were shown as encrypted. I also tested the provisionCertificate API and read the documentation notes and cross-checked all requirements.

Merging this based on review, testing and smoketests. cc @DaanHoogland

Just for the record, I have tested both access (encrypted and unencrypted) and it is working fine:
