WebVirtMgr is a libvirt-based Web interface for managing virtual machines. It allows you to create and configure new domains, and adjust a domain's resource allocation. A VNC viewer over a SSH tunnel presents a full graphical console to the guest domain. KVM is currently the only hypervisor supported.
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.
