The libvirt-sandbox package provides an API layer on top of libvirt-gobject which facilitates the cration of application sandboxes using virtualization technology. An application sandbox is a virtual machine or container that runs a single application binary, directly from the host OS filesystem. In other words there is no separate guest operating system install to build or manage.

At this point in time libvirt-sandbox can create sandboxes using either LXC or KVM, and should in theory be extendable to any libvirt driver.
