Possibility to pass a raw device? #103

Closed olivierlambert closed 4 years ago

olivierlambert commented 4 years ago

Is it possible to pass/attach a raw device (eg a whole disk? or any block device) directly to a VM?

If yes, what would be the best way to do so?

Use blkback. Implementation of datapaths is an exercise for the implementer. Some of the example code in this archived repository might be informative. https://github.com/xapi-project/xapi-storage-plugins/tree/master/datapath.

This repository just contains the API definitions.

Thanks, I'll take a look there 👍

https://github.com/xapi-project/xapi-storage/pull/105 added an up to date example datapath implementation that should be a good starting point for this
