HA-Lizard - High Availability for Citrix XenServer Virtualization Platform

HA-Lizard is the hyperconverged defacto standard for high availability and redundancy in two node XenServer clusters using internal storage. No requirement for external storage or NAS. HA-lizard provides complete automation and hyper-convergence for managing Xen server pools which utilize the XAPI management interface and toolstack (as in Xen Cloud Platform and XenServer).

HA-Lizard - Core Features Auto-start of any failed VMs Auto-start of any VMs on after reboot Detection of failed hosts and automated recovery of any affected VMs Detect and clean up orphaned resources after a failed host is removed Removal of any failed hosts from pool with takeover of services Split brain prevention using heuristics from external network points and quorum HA support for pools with two hosts Structured interface for simple “bolt-on” of fencing scripts Dual operating modes for applying HA to appliances or individual VMs Ability to exclude selected appliances and VMs from HA logic Centralized configuration for entire pool stored in XAPI database Command-line tool for managing global configuration parameters Parameter override available per host for custom configurations Extensive Logging capabilities to system log file Email alerting on configurable triggers Dynamic cluster management logic auto-selects roles and determines recovery policy No changes to existing pool configuration required. All logic is external Full hyper-convergence of Citrix Xenserver, High Availability and Server components

HA-Lizard is available in both Manual and Automated installation to match your requirements. HA-Lizard also provides software for deploying iSCSI High Availability in a 2-Node XAPI based Xen virtualization environments.
