  • User Networking: Enable removal of redirections ...
    c1261d8d 
    Using the new host_net_redir command you can easily create redirections
on the fly while your VM is running.

While that's great, it's missing the removal of redirections, in case you
want to have a port closed again at a later point in time.

This patch adds support for removal of redirections.

  • Allow monitor interaction when using migrate -exec ...
    8a43b1ea 
    All,
     I've recently been playing around with migration via exec.  Unfortunately,
when starting the incoming qemu process with "-incoming exec:cmd", it suffers
the same problem that -incoming tcp used to suffer; namely, that you can't
interact with the monitor until after the migration has happened.  This causes
problems for libvirt usage of -incoming exec, since libvirt expects to be able
to access the monitor ahead of time.  This fairly simple patch allows you to
access the monitor both before and after the migration has completed using exec.

(note: developed/tested with qemu-kvm, but applies perfectly fine to qemu)

  • fully split aio_pool from BlockDriver ...
    c16b5a2c 
    Now that we have a separate aio pool structure we can remove those
aio pool details from BlockDriver.

Every driver supporting AIO now needs to declare a static AIOPool
with the aiocb size and the cancellation method.  This cleans up the
current code considerably and will make it cleaner and more obvious
to support two different aio implementations behind a single
BlockDriver.

  • qcow: add qcow_aio_setup helper ...
    ad53089b 
    [this one is required for [PATCH] fully split aio_pool from BlockDriver,
 sorry for not sending it out earlier]

Add a qcow_aio_setup helper to qcow to shared common code between
the aio_readv and aio_writev methods.  Based on the function with
the same name in qcow2.

  • raw-posix: fix hdev_create ...
    4099df58 
    We do need hdev_create unconditionally on all platforms so that qemu-img
create support for host device works on all platforms.

Also relax the check to allow character devices in addition to block
devices.  On many Unix platforms block devices have buffered block
nodes and unbuffered character device nodes, and on FreeBSD the block
nodes don't even exist anymore.  Also on Linux we do support the
/dev/sgN scsi passthrough devices through the host device driver,
and probably the old-style /dev/raw/rawN raw devices although I haven't
tested that.

  • fix raw_pread_aligned return value ...
    94c6d6d8 
    raw_pread_aligned currently returns the raw return value from
lseek/read, which is always -1 in case of an error.  But the
callers higher up the stack expect it to return the negated
errno just like raw_pwrite_aligned.

  • VNC: Fix memory allocation (wrong structure size). ...
    afd32160 
    Pointer vs addresses a VncDisplay structure,
so it is sufficient to allocate sizeof(VncDisplay)
or sizeof(*vs) bytes instead of the much larger
sizeof(VncState).

Maybe the misleading name should be fixed, too:
the code contains many places where vs is used,
sometimes it is a VncState *, sometimes it is a
VncDisplay *. vd would be a better name.

    44ff42de 
    This is a preparation patch with no functional changes. It moves the allocation
of new refcounts block to a new function and makes update_cluster_refcount (for
one cluster) call update_refcount (for multiple clusters) instead the other way
round.

    cab3c825 
    When a reset is requested, the current e1000 emulation never clears the
reset bit which may cause a driver to hang. This patch masks the reset
bit out when setting the control registert, so the reset is immediately
completed.

  • Fix output of uninitialized strings ...
    8cf07dcb 
    Commit ffad4116 removed the "scratch buffer"
from check_params, but didn't care for the error messages which actually
included this string to tell the user which option was wrong. Now this string
is uninitialized, so this patch removes it from the message.

This means that the user is only told the whole parameter string and has to
pick the wrong option by himself as the callers of check_params can't know this
value any more. An alternative approach would be to revert that commit and do
whatever is needed to fix the original problem without changing check_params.
