6f0437e8de kvm: Avoid COW if KVM MMU is asynchronous
Avi Kivity wrote:

Done in v2:

---------->

If the KVM MMU is asynchronous (kernel does not support MMU_NOTIFIER),
we have to avoid COW for the guest memory. Otherwise we risk serious
breakage when guest pages change there physical locations due to COW
after fork. Seen when forking smbd during runtime via -smb.

89ee676ead vnc: fix server surface pixel format.
Format must be identical to the guest surface, we can't work with
the 32 bpp used by the default surface allocator.

Without this patch vnc doesn't get the conversions right when sending
pixel data to the client.  The bug triggers if
  (a) the client doesn't support WMVi, and
  (b) the guest screen depth is != 32 bpp.

1063b8b15f virtio-blk: add SGI_IO passthru support
[had the qemu list address wrong the first time, reply to this message,
 not the previous if you were on Cc]

Add support for SG_IO passthru (packet commands) to the virtio-blk
backend.  Conceptually based on an older patch from Hannes Reinecke
but largely rewritten to match the code structure and layering in
virtio-blk.

Note that currently we issue the hose SG_IO synchronously.  We could
easily switch to async I/O, but that would required either bloating
the VirtIOBlockReq by the size of struct sg_io_hdr or an additional
memory allocation for each SG_IO request.
