The obvious answer is to specify only a username and password. I have a suspicion that you tried it, and it didn't work for you? In that case, perhaps you can add more details to your questions:

- what template/image did you use
- where did you get it
- what did you configure
- what was the result
- what if any additional troubleshooting did you do

I tried specifying only user/pass. But I can not login.

I need to login with ssh private key.

If you set everything up properly, then when you run:
qm terminal [VMID]
You will be able to login with your username and password.

After you are logged in, you can then examine the running VM and you will find:

cat /etc/ssh/sshd_config.d/60-cloudimg-settings.conf
PasswordAuthentication no

This is common to all modern cloud images produced by the vendors. If you want to change this, you will need to create a custom CloudInit, or modify the image, or create your own.
