NiftyName is a system for creating and managing virtual machine pools and all related components such as storage, private and public networks. It is intended to be used as a free alternative to Amazon EC2 and Microsoft Azure. All components have been designed for multi-site active redundancy, though this is not supported yet. Its architecture is based on documented XML-RPC (SSL) Web services, so you can make your own derivative tools for it. Console and GTK+ client applications are provided. VMs are based on KVM. It supports IPv6, private VLANs, multiple interfaces, user/client management, permissions, and roles.
UnifiedSessionsManager is a unified and simplified interface for the use and management of local and remote sessions on physical and virtual machines. It provides management of distributed and stacked virtual machines, management of desktops and workspaces on multiple monitors, seamless access to all types of sessions, and support of encrypted connections using SSH.
Karesansui is a virtualization management console with a Web-based user interface that supports Linux servers. It allows virtual machine creation, start up, suspension, snapshot, and CPU/RAM allocation, all from a Web browser. The Xen hypervisor is supported. A RESTful architecture is implemented with HTTP-based APIs.
slkvm is an application to provide some system tools to work with clustering and virtualization. It focuses on depending on as few external tools as possible but to also support as many virtualization technologies as possible. It works in a cluster environment where heartbeat runs virtual machines of nodes that have failed. It builds an "unheaded" cluster to avoid having a clear point of failure. It is able to build a two node cluster with everything redundant. It avoids compiling a new kernel or newer version of applications, so you can benefit from Debian security updates.
OpenNode is a server virtualization solution that provides an easy-to-use (CentOS/RHEL based) bare-metal ISO installer that supports both OpenVZ container-based and KVM full virtualization technology on the same host. The OpenNode ISO installer will set up a minimal CentOS server system with the following features: a RHEL kernel (provided by OpenVZ project) modified to support both openvz and kvm virtualization, libvirt management interface support for openvz and kvm hypervisors, func (https://fedorahosted.org/func/) client support for central management purposes, and VM template downloads provided by the opennode TUI utility.
KaOS is a lightweight, multi-purpose embedded Linux platform designed for virtualization and cloud computing applications. KaOS is based on Linux KVM and is a true enterprise grade hypervisor platform. KaOS makes it easy to deploy KVM based virtualization solutions. KaOS is a lightweight platform, less than 10MB in size. The SDK provides everything necessary to rebuild the platform and comes with scripts to assist with building a KaOS-enabled Linux kernel. KaOS has a menu-driven CLI called AppQueue and a management process that replaces init and other functions called kattach.
Proxmox is a Debian-based bundle of OpenVZ, KVM, and a Web based management GUI. It supports high-performance container-based virtualization of Linux workloads, as well as lower performance KVM hardware assisted virtualization. It supports any hardware that the Linux kernel supports, and will permit live migration of running OSIs with shared storage configurations (DRBD, CIFS, NFS, etc.). It comes bundled with many virtual appliance templates (Drupla, Moodle, FreePBX, etc.) and generic OSI appliances (Fedora, Debian, Ubuntu), as well as a faculty for building arbitrary Linux based appliances. It can be used for virtual desktop infrastructure (VDI) and virtual server infrastructure (VSI). It supports almost any x86/x64 OS in a KVM container and any Linux-based OS in OpenVZ.
