Thank you! It does solve the problem!

I'm still trying to do that as for sometimes the VM just get stuck where I can't see any message. I'm currently testing different configurations and my conclusion is: VM could get stuck with only networkDevices, storageDevices and serialPorts added, and other devices have no influence on it. It seems only affect VZEFIBootLoader, VZLinuxBootLoader seems not affected. There are plenty of space on the host, and stuck could still happen if I pre-allocate all disk space using dd.

I have put the screenshot on the reply.
