Xen versions and features support matrix

This table summarises the support status of Xen releases, and of individual features within each release.

Important notes

The matrix is extracted automatically from the formal support status documents in each Xen release. The full formal support status document is linked to from the column heading for each version.

The individual entries are summaries; where a specific entry has more information in the full document a link, denoted [*], is provided. The statuses Supported, Experimental, and so on, are likewise defined in the full document.

Sometimes the same feature, or a similar feature, is named differently in the documentation for different releases. In such cases the table will show it as two separate features, with a discontinuity in support, even though support may have been continuous.

The support status of versions earlier than listed here is documented on the wiki.
