Virt-rescue is particularly suited to rescuing a virtual machine that has failed to start. If a VM doesn’t boot, you can simply launch a rescue shell on the VM or disk image using virt-rescue and try to fix it using the standard Linux commands.
You can use virt-rescue on any disk image file or device, not just a virtual machine. For example, it can be used on USB drives, SD cards and hard disks. It doesn’t require root permission unless you need root to open the disk image. Virt-rescue is part of libguestfs which provides a lot of command line utilities to access and modify virtual machine disk images.
