virt-tools (coming soon) Virt-tools is a suite of tools for managing virtual machines, including virt-uname, virt-ifconfig, virt-ps, virt-uptime, virt-dmesg, and more. At the moment you have to compile from source from the virt-tools code repository.
virt-p2v virt-p2v running Virt-p2v can migrate physical machines to virtual guests (P2V), virtual guests to virtual guests (V2V) and virtual guests back to physical machines (V2P). Amongst other features it lets you resize partitions, install paravirt drivers and change how the virtual hardware is configured after migration.
virt-what Virt-what is a shell script to detect if we are running in a virtual machine. It can detect a number of different forms of virtualization.
