Terms
| Term | Definition |
|---|---|
| Appliance | A virtual machine containing the management software and its operating system. Its address is separate from the hypervisor host address. |
| Backup | A copy kept separately for recovery. Verify it by restoring it; a snapshot on the original storage is not an independent backup. |
| Host | The machine running the hypervisor and hosting virtual machines. |
| Pool | A group of hypervisor hosts managed together. Shared-storage and migration requirements depend on the intended setup. |
| Snapshot | A point-in-time state of a VM or virtual disk. It depends on the original storage and does not replace an independent backup. |
| Storage repository (SR) | A storage location managed by the hypervisor for virtual disks or installation media. |
| Virtual machine (VM) | A guest system with virtual CPU, memory, disks and network interfaces. |
| XO Lite | The management interface served by the host. It is distinct from Xen Orchestra running in the XOA-HL appliance. |
