VMmanager
VMmanager is a commercial Linux-based Server virtualization software control panel or type II OpenVZ / KVM hypervisor. The panel is developed by ISPsystem hosting software developing company.
VMmanager takes control of virtual environments: it helps creating and provisioning VPS, as well as building clusters of virtual machines across different physical servers, all managed from a single panel.
VMmanager is alternative to such virtualisation tools as SolusVM, Proxmox, Virtualizor, VMware vSphere.
Version history
VMmanager was first released in 2004.

High-availability cluster
VMmanager Cloud allows to deploy high-availability clusters and uses QEMU-KVM virtualization. It uses Corosync to detect availability of The Cluster. If one of the servers is down, VMmanager distributes its virtual machines between the remaining nodes.
In the simplified form this mechanism works as follows:
- The system identifies the cluster node with the lowest number of virtual machines.
- It checks whether there is enough RAM to locate the machine.
- If there is enough memory on a node for the pertinent machine, VMmanager CREATES a new virtual machine on this node.
- If there is not enough memory, the system checks the other nodes with more virtual machines.
VMmanager Cloud supports file system storage, LVM, Network LVM, iSCSI and Ceph (in particular RBD (RADOS Block Device), one of Ceph implementations).
