VNC only from master in federation setup

Hello,

I have configured two OpenNebula 5.6 instances in federated setup. Currently I’m able to open VNC console of any of the VM in the slave zone only if I first log-in in to the master and therefore switch to the slave. If I’m logged-in directly to the slave, the VNC buttons are unavailable in Sunstone UI.

Is there a way this behaviour to be changed?

Best regards,
NT

I’m also impacted by this issue.
