For a brief summary of Xapi terminology, see:

https://xapi-project.github.io/xen-api/overview.html#object-model-overview

Xapi contains functionality to backup and restore metadata about Virtual

Machines and Storage Repositories (SRs).

The metadata itself is stored in a Virtual Disk Image (VDI) inside an

SR. This is used for two purposes; a general backup of metadata

(e.g. to recover from a host failure if the filer is still good), and

Portable SRs (e.g. using an external hard drive to move VMs to another

host).

Metadata is only restored as an explicit administrator action, but

occurs in cases where the host has no information about the SR, and must

locate the metadata VDI in order to retrieve the metadata.

The metadata VDI is located by searching (in UUID alphanumeric order)

each VDI, mounting it, and seeing if there is a suitable metadata file

present. The first matching VDI is deemed to be the metadata VDI, and

is restored from.

In the general case, the content of VDIs ar
