Virt-get-kernel extracts a kernel/initrd from a disk image. Virt-inspector examines a virtual machine and tries to determine the version of the OS, the kernel version, what drivers are installed, whether the virtual machine is fully virtualized (FV) or para-virtualized (PV), what applications are installed and more. Virt-log is a command line tool to display the log files from a virtual machine. Virt-ls is a command line tool to list out files in a virtual machine. Virt-make-fs is a command line tool to build a filesystem out of a collection of files or a tarball.

Virt-sparsify makes virtual machine disk images sparse (thin-provisioned). Virt-sysprep lets you reset or unconfigure virtual machines in preparation for cloning them. Virt-tail follows (tails) a log file within a guest, like ’tail -f’. Virt-tar-in and virt-tar-out are archive, backup and upload tools for virtual machines.
