SVL (System Call Virtualisation Layer) is a C++ library that can be used to detect, abort, and rewrite system calls. The possible uses include, but are not limited to, studying the system call trace of a program; sandboxing a program to tighten security; or selectively rerouting system calls, such as file operations, to different paths or even different sytems to create distributed architectures. SVL allows you to change the low level constructs for system call invocation by allowing you access to both the registers and the target program's memory. As well as having the low level access, SVL has high level classes for dealing with the major syscall operation types.
Cantivo Linux is a distribution and platform for desktop/server virtualization using the KVM hypervisor and SPICE protocol, managed from an intuitive Web interface. After your virtual desktops are setup, you can use a powerful multi-platform client to enjoy unsurpassed multimedia capabilities, streaming from your virtual desktops to anywhere in your network, and optionally let your users authenticate using RFID or NFC tokens.
confinedrv creates a new device node /sdx under /dev/mapper which mirrors the given base drive with certain partitions faded out and other partitions limited to read-only or read-write access. It is commonly used to safely boot an existing OS installation with Qemu or any other virtualization software from the same hard disk as the host operating system has been booted from.
