Subject: [PATCH] qemuDomainValidateStorageSource: Reject unsupported slices
|
|
MIME-Version: 1.0

Content-Type: text/plain; charset=UTF-8

We support explicit storage slices only when using blockdev. Storage
|
|
slices expressed via the backing store string are left to qemu to
|
|
open correctly.
|
|
|
|
Reject storage slices configured via the XML for non-blockdev usage.
