Even if the VM is already stopped, we cannot assume that all data has already been successfully flushed to disk. The flush during the previous vm_stop() could have failed.

2013-07-19block-migration: efficiently encode zero blocksPeter Lieven
this patch adds a efficient encoding for zero blocks by adding a new flag indicating a block is completely zero. additionally bdrv_write_zeros() is used at the destination to efficiently write these zeroes. depending on the implementation this avoids that the destination target gets fully provisioned.

2013-07-19dataplane: sync virtio.c and vring.c virtqueue stateStefan Hajnoczi
Load the virtio.c state into vring.c when we start dataplane mode and vice versa when stopping dataplane mode. This patch makes it possible to start and stop dataplane any time while the guest is running. This will eventually allow us to go back to QEMU main loop for bdrv_drain_all() and live migration. In the meantime, this patch makes the dataplane lifecycle more robust but should make no visible difference. It may be useful in the virtio-net dataplane effort.

2013-07-18monitor: maintain at most one G_IO_OUT watchLaszlo Ersek
When monitor_flush() is invoked repeatedly outside the monitor_unblocked() callback, for example from tlb_info() -> ... -> print_pte(), several watches may be added for the same event. This is no problem per se because the extra monitor_unblocked() callbacks are harmless if mon->outbuf is empty, the watches will be removed gradually. However a big number of watches can grow "gpollfds" without limit in glib_pollfds_fill(), triggering a -1/EINVAL condition in g_poll(). Keep at most one such watch, by following the pattern observable in eg. commits c874ea97 and c3d6b96e. The change has no effect when monitor_unblocked() calls monitor_flush() (when the watch can either be removed or renewed 1-for-1), but non-callback contexts won't create an additional watch when the monitor already has one.

2013-07-18char: io_channel_send: don't lose written bytesLaszlo Ersek
The g_io_channel_write_chars() documentation states, bytes_written: The number of bytes written. This can be nonzero even if the return value is not G_IO_STATUS_NORMAL. [...] io_channel_send() could lose such bytes before. Furthermore, the (status == G_IO_STATUS_EOF) condition used to evaluate to constant false whenever it was reached. When that condition actually held, it always led to -1 / EINVAL. This patch (almost) distinguishes G_IO_STATUS_EOF only when no bytes have been written, and then treats it as an error.

access_size_min can be 1 because erroneous accesses must not crash QEMU, they should trigger exceptions in the guest or just return garbage (depending on the CPU). I am not sure I understand the comment: placing a 4-byte field at the last byte of a region makes no sense (unless impl.unaligned is true), and that is why memory.c:access_with_adjusted_size does not bother with minimums larger than the remaining length. access_size_max can be mr->ops->valid.max_access_size because memory.c can and will still break accesses bigger than mr->ops->impl.max_access_size.
