[Qemu-devel] [PATCH RFT 0/5] QOM realize for virtio

["Andreas Färber" <afaerber@suse.de>]

Hello,

This series converts virtio devices to QOM realize/unrealize.
It is intended as base for fixing virtio-net initialization order issues,
as reported by Jesse. Only partially tested though.

Note that while VirtioDevice was setting a DeviceClass::exit callback
for cleaning up the bus name, this was overwritten by most derived classes.
That is fixed as part of this conversion.

Similarly, virtio_scsi_common_{init,exit} can be moved to VirtIOSCSICommon now.
This has the side-effect that the two SCSI subclasses now perform some
initializations after the common SCSI implementation has invoked
virtio_bus_plug_device().

As a follow-up, VirtIOSerialPort is also converted to QOM realize/unrealize.
As a side-effect, virtio-console realization is changed from in-order to pre-order.

Incidentally I stumbled over a minor cleanup issue with virtserialport.
