qm-guest-passwd:tldr:36fa1

This command is used to set a password for a specified user in a virtual machine (VM) using the qm command. Here is a breakdown of the command and its arguments:

• qm: qm is a command-line tool used to manage Proxmox Virtual Environment (PVE) virtual machines and containers.
• guest: This subcommand of qm is used to manage guest-related settings in a virtual machine.
• passwd: This subcommand is used to set or change the password of a user in a virtual machine.
• ${vm_id}: This is a placeholder for the ID of the virtual machine where the password for the user is being set. You need to replace ${vm_id} with the actual ID of the target VM.
• ${username}: Similar to ${vm_id}, this is a placeholder for the username of the user whose password is being set. Replace it with the actual username.
• --crypted 1: This option indicates that the password provided will be in encrypted form. The value 1 suggests it is already encrypted. If the password is not encrypted, you may need to use the --iscrypt 0 option to indicate that the provided password needs to be encrypted before being set.

Overall, this command is used to set the password of a specified user in a virtual machine, considering that the password is already encrypted.
