libguestfs is a set of tools for accessing and modifying virtual machine (VM) disk images. You can use this for viewing and editing files inside guests, scripting changes to VMs, monitoring disk used/free statistics, P2V, V2V, performing partial backups, cloning VMs, and much more. libguestfs can access nearly any type of filesystem including: all known types of Linux filesystem (ext2/3/4, XFS, btrfs, etc.), any Windows filesystem (VFAT and NTFS), any Mac OS X and BSD filesystems, LVM2 volumes, MBR and GPT disk partitions, raw disks, qcow2, CD and DVD ISO images, SD cards, and dozens more. libguestfs doesn't need root permissions.
Xvisor is a type-1 hypervisor that aims to provide a monolithic, light-weight, portable, and flexible virtualization solution for ARMv5, ARMv6, ARMv7a, ARMv7a-ve, ARMv8a, x86_64, and other CPU architectures. It primarily supports full virtualization, and hence supports a wide range of unmodified guest operating systems. Paravirtualization is optional and is supported in an architecture independent manner (such as VirtIO PCI/MMIO devices) to ensure that no changes are required in the guest OS.
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.
UCS is a reliable, pre-configured Linux server operating system featuring: Active Directory-like domain services compatible with Microsoft Active Directory; a mature and easy-to-use Web-based management system for user, rights, and infrastructure management; a scalable underlying concept suited for single server scenarios as well as to run and manage thousands of clients and servers for thousands of users within one single UCS domain; an app center providing single-click installation and integration of many business applications from 3rd parties and Univention; management capabilities to manage Linux- and UNIX-based clients; and command line, scripting interfaces, and APIs for automatization and extension. Its purpose is to provide Microsoft Server-like services on the cloud or on the premises, to run and operate corporate IT environments with Windows- and Linux-based clients, and to extend those environments with proven enterprise software.
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.
NexentaStor is a unified storage solution that installs on standard hardware and provides enterprise class storage at a fraction of the cost of legacy, proprietary storage solutions. NexentaStor is particularly well suited for virtualized environments thanks to the ability of NexentaStor to eliminate duplication of primary data storage, to manage the storage for virtual environments from one interface, and to leverage SSDs to address the random I/O and boot storm issues with virtual environments.
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.
Surealived is a effective LVS (Linux Virtual Server) service tester. It is based on epoll and allows you to detect your hosts' state using HTTP, TCP, DNS, exec, and a universal LUA embedded tester. SSL is also supported. Testers are dynamic modules, and you can extend and write your own modules. You can also dynamicaly change the weight or set real states at run-time. Test states are injected into the kernel IPVS table using the ipvssync application. Configuration is highly extensible, so many testing protocols can be implemented easily.
