Collax V-Cube+ is a HA cluster management suite based on a 64bit Linux system and KVM to provide server virtualization. It offers solutions for single virtualization hosts, as well as high availability management on two or more nodes, allowing embedded HA storage using DRBD and iSCSI. By using live snapshots, automatic live migration, and incremental backups, the availability of virtual machines is increased tremendously in case of hardware and software maintenance or even hardware failures. Virtual network switches and the protocols GVRP, LLDP, and RSTP help to set up a virtual DMZ.
Q-Tubes is a Web-based QEMU/KVM machine manager in Python built around the Pyramid Web framework. Its goal is to allow management of QEMU/KVM networks across single host instances, and ultimately across server farms. It supports minimal VM instances with disk support and basic network configuration (no user-space network yet), and basic VDE switch configurations. It provides a WSGI interface for deployment behind WSGI-aware servers, or provides its own basic server (python-waitress) for simple instances. The application is under steady development and has a moderate number of (Python) dependencies. Installation in a virtualenv is strongly recommended. It requires QEMU/KVM, VDE, and Python 2.7 or later.
kvm-simple-init can perform the following actions on a KVM machine: start, stop, kill, and restart. It focuses on simplicity, and is fully implemented in just a few hundred lines of shell script. It is intended for people who do not want to run libvirt just for running a few VMs, or people who prefer to manage flat configuration files using their preferred configuration management system. It does not provide complicated configuration file format or parameters. Only two pieces of information are needed: a QEMU monitor port for the machine and the full KVM command line needed to start the machine (gives full configuration freedom). kvm-simple-init can be used directly as a system init script for starting all KVM machines on a host machine. Just drop it in /etc/init.d, and enable it with the tools provided by your UNIX distribution. kvm-simple-init was inspired by the init script of FreeBSD jails.
