Im having this strange issue when I open the console from a cloud-init vm on a node other than the one im actually on it glitches noVNC.

So Im pointing my browser to node A then when I open a cloud-init vm on node B the console keeps restarting. Works fine when I open a cloud-init vm on node A. If I point my browser to node B I get the same behavior vice-versa.
 
check if you can ssh from one node to the other without password, this is necessary for the cross node consoles to work
also pleas post the output of pveversion -v

Yes ssh to the other cluster nodes work as it should.

is there anything in the console task log or syslog that indicates any error?
 
hi, yes i can now reproduce it, it seems to be bug with the combination of remote node -> novnc -> serial display
can you open a bug report here : https://bugzilla.proxmox.com/
so that we can track the progress
