VirtIO specific error types

Variants

InvalidQueue

Invalid queue configuration

QueueNotReady

Queue not ready for operation (not configured yet)

InvalidDescriptor

Invalid descriptor

InvalidAccessWidth

Invalid access width for MMIO operation

DeviceNotReady

Device not ready

InvalidDeviceIndex

Invalid device index

BackendError

Backend operation failed

MemoryError

Memory access error

InvalidConfig

Invalid configuration

FeatureNegotiationFailed

Feature negotiation failed

InvalidRequest

Invalid request

NotSupported

Operation not supported

InvalidBufferSize

Invalid buffer size

InvalidSector

Invalid sector

InvalidRegister

Invalid register

InvalidAddress

Invalid address or address translation failed

RingMisaligned

One or more virtqueue rings are misaligned (desc 16B, avail 2B, used 4B)

RingOverlap

The virtqueue ring regions overlap each other

InvalidRingLayout

The virtqueue ring layout is invalid (zero address, region overflow, or a ring region lies outside the guest address space)

QueueFaulted

The queue is faulted after a runtime ring/descriptor failure and must be reset before further use. Unlike QueueNotReady, which is a normal pre-configuration state, a faulted queue has served requests and hit a runtime failure; its guest-serving data paths (pop/complete, chain walks and data access) reject with this error and write no guest memory until reset, while the configuration setters remain usable.

NotFound

Resource not found

WouldBlock

The operation is valid but cannot complete until asynchronous backend work makes progress.

InvalidInput

Invalid input
