vpmem

type Controller ¶

type Controller struct {
	// contains filtered or unexported fields
}

The controller manages all VPMem attached devices and guest mounted directories.

It is required that all callers:

1. Obtain a reservation using Reserve().

2. Use the reservation to Mount() to ensure resource availability.

3. Call Unmount() to release the reservation and all resources.

If Mount() fails, the caller must call Unmount() to release the reservation and all resources.

If Unmount() fails, the caller must call Unmount() again until it succeeds to release the reservation and all resources.
