[Qemu-trivial] [PATCH] qerror: Improve QERR_DEVICE_NOT_ACTIVE message

[Hani Benhabiles]

The error message as currently used is confusing as there are no "balloon" or
"spice" devices.

(qemu) balloon 1024
balloon: Device 'balloon' has not been activated

With this patch:

(qemu) balloon 1024
balloon: No balloon device has been activated
