Subject: [PATCH] qemu: use QEMU_CAPS_STORAGE_WERROR for disk-error attributes

When moving the formatting of this attributes from -drive
|
|
|
b971b8 |
to -device, the QEMU_CAPS_USB_STORAGE_WERROR capability
|
|
|
b971b8 |
was used, because usb-storage was the last device to gain
|
|
|
b971b8 |
this capability.
|
|
|
b971b8 |
|
|
|
b971b8 |
However this lead to the assumption that QEMU binaries
|
|
|
b971b8 |
without the usb-storage device do not support this,
|
|
|
b971b8 |
leading to breakage on s390x with blockdev.
