      Expand cache= option and use write-through caching by default · 9f7965c7
      由 aliguori 提交于 
      This patch changes the cache= option to accept none, writeback, or writethough
to control the host page cache behavior.  By default, writethrough caching is
now used which internally is implemented by using O_DSYNC to open the disk
images.  When using -snapshot, writeback is used by default since data integrity
it not at all an issue.

cache=none has the same behavior as cache=off previously.  The later syntax is
still supported by now deprecated.  I also cleaned up the O_DIRECT
implementation to avoid many of the #ifdefs.

      Change the way video graphics adapter is selected · 3893c124
      由 malc 提交于 
      Instead of having (current)three command line switches -std-vga,
-cirrusvga and -vmwarevga, provide one -vga switch which takes
an argument, so that:
qemu -std-vga   becomes qemu -vga std
qemu -cirrusvga becomes qemu -vga cirrus
qemu -vmwarevga becomes qemu -vga vmware

Update documentation accordingly.

      add format= to drive options (CVE-2008-2004) · 1e72d3b7
      由 aurel32 提交于 
      It is possible for a guest with a raw formatted disk image to write a
header to that disk image describing another format (such as qcow2).
Stopping and subsequent restart of the guest will cause qemu to detect
that format, and could allow the guest to read any host file if qemu is
sufficiently privileged (typical in virt environments).

The patch defaults to existing behaviour (probing based on file contents),
so it still requires the mgmt app (e.g. libvirt xml) to pass a new
"format=raw" parameter for raw disk images.

Originally noted by Avi Kivity, patch from Chris Wright.
