virtio: Remove duplicate macro definition for max. virtqueues, bump up the max
VIRTIO_PCI_QUEUE_MAX is redefined in hw/virtio.c. Let's just keep it inhw/virtio.h.
Also, bump up the value of the maximum allowed virtqueues to 64. This isin preparation to allow multiple ports per virtio-console device....
virtio-console: qdev conversion, new virtio-serial-bus
This commit converts the virtio-console device to create a newvirtio-serial bus that can host console and generic serial ports. Thefile hosting this code is now called virtio-serial-bus.c.
The virtio console is now a very simple qdev device that sits on the...
virtio-serial-bus: Maintain guest and host port open/close state
Via control channel messages, the guest can tell us whether a port gotopened or closed. Similarly, we can also indicate to the guest of hostport open/close events.

virtio-serial-bus: Add a port 'name' property for port discovery in guests
The port 'id' or number is internal state between the guest kernel andour bus implementation. This is invocation-dependent and isn't part ofthe guest-host ABI.
To correcly enumerate and map ports between the host and the guest, the...

virtio-serial: Add a 'virtserialport' device for generic serial port support
This commit adds a simple chardev-based serial port. Any data the guestsends is forwarded to the chardev and vice-versa.
Sample uses for such a device can be obtaining info from the guest like...
virtio-serial: Use MSI vectors for port virtqueues
This commit enables the use of MSI interrupts for virtqueuenotifications for ports. We use nr_ports + 1 (for control channel) msientries for the ports, as only the in_vq operations need an interrupt on...
Clean-up a little bit the RW related bits of BDRV_O_FLAGS. BDRV_O_RDONLY gone (and so is BDRV_O_ACCESS). Default value for bdrv_flags (0/zero) is READ-ONLY. Need to explicitly request READ-WRITE.
Instead of using the field 'readonly' of the BlockDriverState struct for passing the request,...
pc: add driver version compat properties
This patch adds compat property entries for ide-disk.ver andscsi-disk.ver to pc-0.10 and pc-0.11. With this patch appliedthe scsi and ide disks report "0.10" and "0.11" as version whenyou start qemu with "-M pc-0.10" or "-M pc-0.11"....
