Old version looks like this in info qtree (last four lines):
dev: virtconsole, id ""
dev-prop: is_console = 1
dev-prop: nr = 0
dev-prop: chardev = <null>
dev-prop: name = <null>
dev-prop-int: id: 0
dev-prop-int: guest_connected: 1
dev-prop-int: host_connected: 0
dev-prop-int: throttled: 0
Indentation is off, and "dev-prop-int" suggests these are properties
you can configure with -device, which isn't the case. The other
buses' print_dev() callbacks don't do that. For instance, PCI's
output looks like this:
class Ethernet controller, addr 00:03.0, pci id 1af4:1000 (sub 1af4:0001)
bar 0: i/o at 0xffffffffffffffff [0x1e]
bar 1: mem at 0xffffffffffffffff [0xffe]
bar 6: mem at 0xffffffffffffffff [0xfffe]
Change virtser_bus_dev_print() to that style. Result:
dev: virtconsole, id ""
dev-prop: is_console = 1
dev-prop: nr = 0
dev-prop: chardev = <null>
dev-prop: name = <null>
port 0, guest on, host off, throttle off

Allow client connections for VNC and socket based character
devices to be passed in over the monitor using SCM_RIGHTS.
One intended usage scenario is to start QEMU with VNC on a
UNIX domain socket. An unprivileged user which cannot access
the UNIX domain socket, can then connect to QEMU's VNC server
by passing an open FD to libvirt, which passes it onto QEMU.
{ "execute": "get_fd", "arguments": { "fdname": "myclient" } }
{ "return": {} }
{ "execute": "add_client", "arguments": { "protocol": "vnc",
"fdname": "myclient",
"skipauth": true } }
{ "return": {} }
In this case 'protocol' can be 'vnc' or 'spice', or the name
of a character device (eg from -chardev id=XXXX)
The 'skipauth' parameter can be used to skip any configured
VNC authentication scheme, which is useful if the mgmt layer
talking to the monitor has already authenticated the client
in another way.
* console.h: Define 'vnc_display_add_client' method
* monitor.c: Implement 'client_add' command
* qemu-char.c, qemu-char.h: Add 'qemu_char_add_client' method
* qerror.c, qerror.h: Add QERR_ADD_CLIENT_FAILED

A future patch will introduce a situation where different
clients may have different authentication schemes set.
When a new client arrives, copy the 'auth' and 'subauth'
fields from VncDisplay into the client's VncState, and
use the latter in all authentication functions.
* ui/vnc.h: Add 'auth' and 'subauth' to VncState

Daniel P. Berrange sent a libvirt's patch to support
reboots with the QEMU driver. He implements it in
json model like this:
1. add -no-shutdown in the qemu's option:
qemu -no-shutdown xxxx
2. shutdown the vm by monitor command system_powerdown
3. wait for shutdown event
4. reset the vm by monitor command system_reset
no_shutdown will be reset to 0 if the vm is powered down.
We only can reboot the vm once.
If no_shutdown is not reset to 0, we can reboot the vm
many times.

Serial and parallel devices created with -device are not reported in
the PIIX4 configuration space, and are hence not picked up by the DSDT.
This upsets Windows, which hides them altogether from the guest.
To avoid this, check at the end of machine initialization whether the
corresponding I/O ports have been registered. The new function in
ioport.c does this; this also requires a tweak to isa_unassign_ioport.
I left the comment in piix4_pm_initfn since the registers I moved do
seem to match the 82371AB datasheet. There are some quirks though.
We are setting this bit:
"Device 8 EIO Enable (EIO_EN_DEV8)—R/W. 1=Enable PCI access to the
device 8 enabled I/O ranges to be claimed by PIIX4 and forwarded
to the ISA/EIO bus. 0=Disable. The LPT_MON_EN must be set to enable
the decode."
but not LPT_MON_EN (bit 18 at 50h):
LPT Port Enable (LPT_MON_EN)—R/W. 1=Enable accesses to parallel
port address range (LPT_DEC_SEL) to generate a device 8 (parallel
port) decode event. 0=Disable.
We're also setting the LPT_DEC_SEL field (that's the 0x60 written to
63h) to 11, which means reserved, rather than to 01 (378h-37Fh).
Likewise we're not setting SA_MON_EN, SB_MON_EN (respectively bit 14
and bit 16 at address 50h) for the serial ports. However, we're setting
COMA_DEC_SEL and COMB_DEC_SEL correctly, unlike the corresponding register
for the parallel port.
All these fields are left as they are, since they are probably only
meant to be used in the DSDT.

This patch adds support for a usb-redir device, which takes a chardev
as a communication channel to an actual usbdevice using the usbredir protocol.
Compiling the usb-redir device requires usbredir-0.3 to be installed for
the usbredir protocol parser, usbredir-0.3 also contains a server for
redirecting usb traffic from an actual usb device. You can get the 0.3
release of usbredir here:
http://people.fedoraproject.org/~jwrdegoede/usbredir-0.3.tar.bz2
(getting a more formal site for it is a WIP)
Example usage:

2) Start qemu with usb2 support + a chardev talking to usbredirserver +
a usb-redir device using this chardev:
