I have been trying to create a Linux VM but immediately ran into problems with dynamix.vm.manager trying to remote into the VM using VNC.

It seems some files are missing vm manager:

/usr/local/emhttp/plugins/dynamix.vm.manager/novnc/defaults.json

/usr/local/emhttp/plugins/dynamix.vm.manager/novnc/mandatory.jso

Log output:

How should I go about fixing?

Fixed it.

Per https://github.com/novnc/noVNC/blob/master/defaults.json these files are empty so I just used:

cd /usr/local/emhttp/plugins/dynamix.vm.manager/novnc/

touch defaults.json

touch mandatory.json

and it works.
