      Mingw execve() has a broken signature. Disable this

      don't really need this on Win32 anyway.

      Run tunnelled migration IO in separate thread · 1d916a60
      Daniel P. Berrange 提交于
      By running the doTunnelSendAll code in a separate thread, the
      main thread can do qemuMigrationWaitForCompletion as with
      normal migration. This in turn ensures that job signals work
      correctly and that progress monitoring can be done

      Close all sockets before cancelling QEMU migration · 2bf92bb8
      Daniel P. Berrange 提交于
      Cancelling the QEMU migration may cause QEMU to flush pending
      data on the migration socket. This may in turn block QEMU if
      nothing reads from the other end of the socket. Closing the
      socket before cancelling QEMU migration avoids this possible
      deadlock.

      Ensure we always read a full buffer in tunnelled migration · 74f33246
      Daniel P. Berrange 提交于
      The 'nbytes' variable was not re-initialized to the
      buffer size on each iteration of the tunnelled migration
      loop. While saferead() will ensure a full read, except
      on EOF, it is clearer to use the real buffer size

      Refactor migration completion loop to allow code reuse · 792a5a61
      Daniel P. Berrange 提交于
      The qemuMigrationWaitForCompletion method contains a loop which
      repeatedly queries QEMU to check migration progress, and also
      processes job signals (pause, setspeed, setbandwidth, cancel).
      
      The tunnelled migration loop does not currently support this
      functionality, but should. Refactor the code to allow it to
      be used with tunnelled migration.

      Implement migration v3 protocol in QEMU driver · 2d5caf7a
      Daniel P. Berrange 提交于
      Implement the v3 migration protocol, which has two extra
      steps, 'begin' on the source host and 'confirm' on the
      source host. All other methods also gain both input and
      output cookies to allow bi-directional data passing at
      all stages.
      
      The QEMU peer2peer migration method gains another impl
      to provide the v3 migration. This finally allows migration
      cookies to work with tunnelled migration, which is required
      for Spice seamless migration & the lock manager transfer

      Merge the doNonTunnelMigrate2 and doTunnelMigrate2 methods
      into one doPeer2PeerMigrate2 method, since they are substantially
      the same. With the introduction of v3 migration, this will be
      even more important, to avoid massive code duplication.

      Refactor tunnelled migration methods · 13cb49f8
      Daniel P. Berrange 提交于
      To facilitate the introduction of the v3 migration protocol,
      the doTunnelMigrate method is refactored into two pieces. One
      piece is intended to mirror the flow of virDomainMigrateVersion2,
      while the other is the helper for setting up sockets and processing
      the data.
      
      Previously socket setup would be done before the 'prepare' step,
      so errors could be dealt with immediately, avoiding need to shut
      off the destination QEMU. In the new split, socket setup is done
      after the 'prepare' step. This is not a serious problem, since
      the control flow already requires calling 'finish' to tear down
      the destination QEMU upon several errors.
