[sandbox PATCH 05/10] Add disk support to machine builder

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Use the new disk configuration in the container builder to provide disks in
qemu sandboxes. The disks are virtio devices, but those shouldn't be
known by the user.
