    vnc does not work in cluster

    Hi, I have three nodes in a cluster and when I try to VNC in the other two nodes's VMs, it doesn't work. Only the host node works. From my understanding, it's something to do with ssh? Can someone give a few pointers on how and what to set to have this working properly? Thanks
