balloon: improve error msg when adding second device
A VM supports only one balloon device, but due to several changes
in infrastructure the error message got messed up when trying
to add a second device. Fix it.
Before this fix
Command-line:
qemu-qmp: -device virtio-balloon-pci,id=balloon0: Another balloon device already registered
qemu-qmp: -device virtio-balloon-pci,id=balloon0: Adding balloon handler failed
qemu-qmp: -device virtio-balloon-pci,id=balloon0: Device 'virtio-balloon-pci' could not be initialized
HMP:
Another balloon device already registered
Adding balloon handler failed
Device 'virtio-balloon-pci' could not be initialized
QMP:
{ "execute": "device_add", "arguments": { "driver": "virtio-balloon-pci", "id": "balloon0" } }
{
"error": {
"class": "GenericError",
"desc": "Adding balloon handler failed"
}
}
After this fix
Command-line:
qemu-qmp: -device virtio-balloon-pci,id=balloon0: Only one balloon device is supported
qemu-qmp: -device virtio-balloon-pci,id=balloon0: Device 'virtio-balloon-pci' could not be initialized
HMP:
(qemu) device_add virtio-balloon-pci,id=balloon0
Only one balloon device is supported
Device 'virtio-balloon-pci' could not be initialized
(qemu)
QMP:
{ "execute": "device_add",
"arguments": { "driver": "virtio-balloon-pci", "id": "balloon0" } }
{
"error": {
"class": "GenericError",
"desc": "Only one balloon device is supported"
}
}
