The Proxmox VE HA Manager (pve-ha-manager), the new resource manager for the high availability cluster is one of the main new features. The pve-ha-manager, developed by the Proxmox team, replaces the former rgmanager. The HA manager monitors all virtual machines and containers on the cluster and automatically gets into action if one of them fails. It works out of the box, and additionally watchdog-based fencing simplifies deployments dramatically. The whole HA settings are configured via GUI. This beta version also comes with a brand-new Proxmox HA Simulator allowing users to learn and test all the functionality of the Proxmox VE HA solution prior to going into production. Proxmox VE 4.0 will be the first version to include Linux containers (LXC).
