kvm-vm-add-sshkey

kvm-vm-add-sshkey is a command-line tool that adds an SSH public key to a KVM (Kernel-based Virtual Machine) virtual machine by writing directly to the guest disk while the VM is stopped.

Features

• Appends an SSH public key to the specified user's .ssh/authorized_keys file inside the guest
• Verifies that the target virtual machine is stopped before proceeding
• Sets appropriate ownership and permissions for SSH files

Notes

• This tool requires permissions to run virsh and virt-customize commands with sudo.
• Ensure that the target virtual machine is stopped before running this tool.
• If an authorized_keys file already exists, the new public key will be appended to it. Existing keys will be preserved.

Usage

Basic usage:

$ kvm-vm-add-sshkey [options] VM_NAME

Example:

$ kvm-vm-add-sshkey -user myuser -key /path/to/my/key.pub my-vm
