      qdev: add blocksize property type · 02fda01c
      由 Stefan Hajnoczi 提交于 
      Storage interfaces like virtio-blk can be configured with block size
information so that the guest can take advantage of efficient I/O
request sizes.

According to the SCSI Block Commands (SBC) standard a device's block
size is "almost always greater than one byte and may be a multiple of
512 bytes".  QEMU currently has a 512 byte minimum block size because
the block layer functions work at that granularity.  Furthermore, the
block size should be a power of 2 because QEMU calculates bitmasks from
the value.

Introduce a "blocksize" property type so devices can enforce these
constraints on block size values.  If the constraints are relaxed in the
future then this property can be updated.

Introduce the new PropertyValueNotPowerOf2 QError so QMP clients know
exactly why a block size value was rejected.

      qom: use object_resolve_path_type for links · 11e35bfd
      由 Paolo Bonzini 提交于 
      This allows to restrict partial matches to objects of the expected
type.  It will let people use bare names to reference drives
even though their name might be the same as a device's (e.g.
-drive id=hd0,if=none,... -device ...,drive=hd0,id=hd0).

As a useful byproduct, this fixes a problem with links of interface
type.  When a link property's type is an interface, the code expects
the implementation object (not the parent object) to be stored in the
variable.  The parent object does not contain the right vtable.

      Monitor/QMP: Don't allow cont on bad VM state · 6667b23f
      由 Luiz Capitulino 提交于 
      We have two states where issuing cont before system_reset can
cause problems: RSTATE_SHUTDOWN (when -no-shutdown is used) and
RSTATE_PANICKED (which only happens with kvm).

This commit fixes that by doing the following when state is
RSTATE_SHUTDOWN or RSTATE_PANICKED:

 1. returning an error to the user/client if cont is issued
 2. automatically transition to RSTATE_PAUSED during system_reset

      Introduce a 'client_add' monitor command accepting an open FD · 13661089
      由 Daniel P. Berrange 提交于 
      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.

      guest agent: add guest agent RPCs/commands · e3d4d252
      由 Michael Roth 提交于 
      This adds the initial set of QMP/QAPI commands provided by the guest
agent:

guest-sync
guest-ping
guest-info
guest-shutdown
guest-file-open
guest-file-read
guest-file-write
guest-file-seek
guest-file-flush
guest-file-close
guest-fsfreeze-freeze
guest-fsfreeze-thaw
guest-fsfreeze-status

The input/output specification for these commands are documented in the
schema.

Example usage:

  host:
    qemu -device virtio-serial \
         -chardev socket,path=/tmp/vs0.sock,server,nowait,id=qga0 \
         -device virtserialport,chardev=qga0,name=org.qemu.quest_agent.0
         ...

    echo "{'execute':'guest-info'}" | socat stdio unix-connect:/tmp/qga0.sock

  guest:
    qemu-ga -m virtio-serial -p /dev/virtio-ports/org.qemu.guest_agent.0 \
