kvm-vm-eraser

kvm-vm-eraser is a command-line tool designed to safely erase KVM (Kernel-based Virtual Machine) virtual machines and their associated disk images.

Features

• Checks if the specified VM is running before attempting to erase it
• Undefines the VM using virsh undefine
• Deletes the associated disk image
• Requires sudo privileges for safety and to ensure proper cleanup
• Handles VMs with multiple attached disks, attempting to delete all of them
• Continues the erasure process even if some disk deletions fail, providing warnings for any failed deletions

Notes

• This tool requires sudo privileges to run. It will prompt for your password if necessary.
• The tool will check if the VM is running before attempting to erase it. If the VM is running, it will display an error message and exit.
• Be extremely cautious when using this tool. It will permanently delete the VM and its associated disk image.
• Always ensure you have backups of important data before erasing a VM.
• The tool assumes that the VM name is unique and that there's only one disk associated with the VM.
