VWs stands for "Virtual WorkStation".
It's main repository, bts and wiki is on my site. See also manual page
It is a python script which provides command-line interface to QEMU virtual machines, which simplifies such tasks as creation, device redirection doing snapshots and reverting to them.
It's main features
- No daemons. No extra processes like libvirtd
- No complicated API like libvirt.
- No XML configs. All configuration of vm is stored in the shell script which invokes QEMU with appropriate arguments.
- Transparency. If vws doesn't know how to make something, it doesn't prevent you from interacting with QEMU monitor direcrly or editing start script by hand.
- Runs as ordinary user. QEMU processes run a invoking user. qemu-bridge-helper is used to setup network
- Virtual machines can be freely copied from one physical machines to another using ordinary file operations. VM directory with virtual disks and start script is self-contained.
