I am trying to run a Ubuntu Linux VM from the custom VHD I prepared. I provision the VM but seems there is some issue with the Vm agent and cloud-init.

• Host name/ DNS is not set on boot
• Cloud-init log shows "No instance datasource found! Likely bad things
  to come!"
• Portal shows Linux VM agent is not reachable but actually it is
  running.

Cloud-init log
