Cloud-Init Support is broken in VE 7.0-10

After successful upgrading the server from the latest version 6.x to version 7.0-10 Cloud-Init stopped working. VMs with Cloud-Init cannot boot anymore.

I tried to setup a new VM following by the instructions on but the result the same.

Can anyone suggest to me how to find the cause or how to fix it?

Do the VMs still start, but they don't boot the guest OS?

Please provide the output of pveversion -v, qm config <VMID>, the task log of the VM start.

Here is my versions:
