      Allow monitor interaction when using migrate -exec · 8a43b1ea
      由 Chris Lalancette 提交于 
      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)

      Hardware convenience library · 1ad2134f
      由 Paul Brook 提交于 
      The only target dependency for most hardware is sizeof(target_phys_addr_t).
Build these files into a convenience library, and use that instead of
building for every target.

Remove and poison various target specific macros to avoid bogus target
dependencies creeping back in.

Big/Little endian is not handled because devices should not know or care
about this to start with.

      Fix some issues with QEMUFile · 871d2f07
      由 aliguori 提交于 
      This patch allows QEMUFile's read and write operations to return 
negative error codes.  This is necessary to detect things like closed 
streams during live migration.

It also removes unused code for QEMUFileFD write path.  Finally, it 
makes sure to avoid attempting to flush an output buffer if the file
is only being used for input.  This was spotted by Uri Lublin.

      Introduce v3 of savevm protocol · 9366f418
      由 aliguori 提交于 
      The current savevm/loadvm protocol has some draw backs.  It does not support
the ability to do progressive saving which means it cannot be used for live
checkpointing or migration.  The sections sizes are 32-bit integers which
means that it will not function when using more than 4GB of memory for a guest.
It attempts to seek within the output file which means it cannot be streamed.
The current protocol also is pretty lax about how it supports forward
compatibility.  If a saved section version is greater than what the restore
code support, the restore code generally treats the saved data as being in
whatever version it supports.  This means that restoring a saved VM on an older
version of QEMU will likely result in silent guest failure.

This patch introduces a new version of the savevm protocol.  It has the
following features:

 * Support for progressive save of sections (for live checkpoint/migration)
 * An asynchronous API for doing save
 * Support for interleaving multiple progressive save sections
   (for future support of memory hot-add/storage migration)
 * Fully streaming format
 * Strong section version checking
